Which Airline Is True Blue? Unpacking Loyalty Programs for the Savvy Traveler

I remember a time, not too long ago, when I was utterly bewildered by airline loyalty programs. It felt like every airline had its own cryptic points system, its own tier of elite status with baffling requirements, and its own set of blackout dates that seemed to materialize out of thin air. I’d spend hours poring over spreadsheets, trying to figure out which miles I should be accumulating, and which airline truly offered the best bang for my buck, or rather, for my frequent flyer miles. That feeling of being overwhelmed, of not quite knowing if I was making the most of my travel, is precisely what led me down the rabbit hole to understand what it truly means for an airline to be "true blue" in the eyes of a loyal customer. It's not just about earning miles; it's about the entire experience, the perceived value, and ultimately, the feeling of being genuinely appreciated.

So, which airline is true blue? In essence, a "true blue" airline is one whose loyalty program consistently delivers exceptional value and a superior customer experience that aligns with your individual travel habits and priorities. It’s an airline that makes you feel like your business is genuinely valued, not just tolerated. This doesn't necessarily mean it's the cheapest option or the one with the most direct flights, though those can certainly be contributing factors. Rather, it speaks to a deeper relationship built on trust, transparency, and tangible benefits that genuinely enhance your travel journey.

When we talk about airlines being "true blue," we're delving into the intricate world of airline loyalty programs, often referred to as frequent flyer programs. These programs are the lifeblood of customer retention for major carriers. They are designed to incentivize repeat business by offering rewards, perks, and elevated experiences to their most loyal passengers. But as anyone who has tried to navigate this landscape knows, not all programs are created equal. Some are straightforward and rewarding, while others can feel like a labyrinth designed to confuse and ultimately underdeliver. The quest to find a "true blue" airline is, therefore, a quest for an airline that offers a loyalty program that genuinely works for *you*.

My own journey started with collecting miles indiscriminately, hoping for the best. I’d sign up for every program, collect a few thousand miles here and there, and then be frustrated when I didn’t have enough for a decent redemption. It wasn't until I started to focus my spending with a particular airline and its partners, and really understood the nuances of their program, that I began to see the real value. This shift in perspective is crucial. A "true blue" airline isn't just about the airline itself, but about how its loyalty program aligns with your personal travel patterns. Are you a domestic flyer who prioritizes convenience and seat upgrades? Or are you an international adventurer looking for aspirational redemptions in premium cabins? The answers to these questions will significantly shape which airline is "true blue" for you.

Let's start by dissecting what makes an airline's loyalty program truly stand out. It’s a multifaceted proposition, encompassing not just the accumulation of points or miles, but also the ease of redemption, the quality of elite status benefits, and the overall customer service experience when things inevitably go awry. For an airline to be considered "true blue," it needs to excel in several key areas. These aren't just nice-to-haves; they are the foundational elements that build genuine loyalty.

The Pillars of a "True Blue" Airline Loyalty Program

Earning Potential: More Than Just Miles Per Mile

The most fundamental aspect of any loyalty program is how you earn rewards. A "true blue" airline will offer a clear, competitive, and generous earning structure. This often goes beyond a simple "X miles per dollar spent." We're looking for:

Bonus Earning Opportunities: This includes earning bonus miles on specific routes, during promotional periods, or when flying with partner airlines. For instance, some airlines offer a significant bonus for booking directly through their app or website.
Elite Status Bonuses: As you climb the loyalty tiers, the mileage earning rate should increase substantially. A top-tier elite member might earn double or even triple the base miles on every flight. This is a critical component for frequent travelers who spend a lot of time in the air.
Credit Card Partnerships: While not directly part of the airline's operational program, co-branded credit cards are a massive component of earning. A "true blue" airline will have a strong, value-driven credit card that offers substantial welcome bonuses and ongoing earning rates that align with everyday spending. Think about earning bonus points on groceries, dining, and gas, which are often significant spending categories for many people.
Partner Earning: The ability to earn miles on flights with alliance partners or other affiliated airlines is a huge plus. This broadens your earning potential significantly, especially if your preferred "true blue" airline doesn't fly to all your desired destinations.

I've found that airlines with flexible earning structures, where you can earn through a variety of means beyond just flying, tend to be the most rewarding. For example, if you can earn a substantial number of miles through a credit card, or by booking hotels and rental cars through their travel portal, it feels more integrated into your overall spending habits, making the accumulation process less of a chore and more of a natural consequence of your lifestyle.

Redemption Value: Making Those Miles Count

Earning miles is only half the battle. The real test of a "true blue" airline lies in how easily and valuably you can redeem those hard-earned miles. This is where many programs fall short. A program that is truly "true blue" will offer:

Availability: This is perhaps the biggest sticking point for many travelers. A "true blue" airline will offer a reasonable amount of award seat availability, especially in economy and business class. Some airlines are notorious for making it incredibly difficult to find award seats, even months in advance.
Low Redemption Rates: The number of miles required for a flight should be competitive. We're looking for programs that don't excessively devalue their miles over time.
No Blackout Dates (or very few): The ideal program would have no blackout dates, meaning you can redeem miles for any available seat on any flight. While this is rare, a "true blue" airline will have minimal, if any, blackout periods.
Fuel Surcharge Transparency: Some airlines add significant fuel surcharges to award tickets, which can dramatically increase the out-of-pocket cost. A "true blue" program will be transparent about these fees and, ideally, keep them low or non-existent.
Flexibility: The ability to change or cancel award tickets without exorbitant fees is another hallmark of a good program.

In my experience, a program that offers a "fixed value" redemption for miles can sometimes be predictable, but often lacks the aspirational value of a program with dynamic pricing that, when timed correctly, can offer incredible redemptions. The sweet spot, in my opinion, is a program that offers a good mix of both – predictable economy redemptions and occasional opportunities for amazing premium cabin deals.

Elite Status Perks: Beyond the Fast Track

For those who travel frequently, elite status in an airline loyalty program can be a game-changer. A "true blue" airline recognizes its elite members with benefits that genuinely enhance their travel experience. These should include:

Complimentary Upgrades: This is often the most coveted perk. A "true blue" airline will offer a robust upgrade system, with a high likelihood of receiving complimentary upgrades to higher cabin classes, especially on domestic routes. The priority for these upgrades should also be fair and transparent.
Lounge Access: Access to airline lounges provides a comfortable and productive environment to relax, work, or dine before a flight. This is a significant perk, especially for those who travel often.
Priority Services: This includes priority check-in, priority security screening, priority boarding, and priority baggage handling. These services can save considerable time and reduce stress.
Bonus Baggage Allowance: Extra free checked bags are a lifesaver, particularly for family travelers or those on longer trips.
Dedicated Customer Service: Elite members should have access to a dedicated phone line or support channel for quicker assistance with rebookings, changes, or any issues that arise.

I've found that the *quality* of elite benefits can vary wildly. Some airlines offer upgrades that are rarely granted, while others have lounges that are perpetually overcrowded. A "true blue" airline will offer benefits that are not just listed on a webpage, but are consistently delivered and genuinely appreciated by their elite members.

Customer Service: The Human Element

Even with the best loyalty programs, travel can be unpredictable. Flights get delayed or canceled, connections are missed, and sometimes things just go wrong. This is where customer service becomes paramount. A "true blue" airline will have:

Responsive and Empathetic Staff: When you need assistance, you want to interact with staff who are knowledgeable, friendly, and empowered to resolve your issues efficiently.
Proactive Communication: Airlines that keep passengers informed about delays or disruptions via text, email, or app notifications are demonstrating a commitment to customer care.
Fair Rebooking Policies: In the event of significant disruptions, a "true blue" airline will have fair and flexible rebooking policies that prioritize getting you to your destination with minimal hassle.
Effective Complaint Resolution: If you do have a complaint, a "true blue" airline will have a clear and effective process for addressing it, and will offer reasonable compensation or solutions.

This is an area where my personal experiences have really shaped my opinion. I’ve had incredible experiences with airline staff who went above and beyond to help me during stressful travel situations, and I’ve also encountered agents who seemed indifferent. Those airlines with consistently positive customer service interactions are the ones that truly earn my loyalty, regardless of the intricacies of their points system.

Identifying the "True Blue" Contenders: A Deep Dive into Major Airlines

Now, let’s get down to brass tacks. Which major airlines, particularly in the United States, are generally considered to be "true blue" by a significant portion of their loyal customer base? It’s important to remember that individual experiences can vary, and what makes an airline "true blue" for one person might not hold true for another. However, based on program structure, redemption ease, elite benefits, and general customer sentiment, some airlines consistently rise to the top.

American Airlines (AAdvantage Program)

American Airlines’ AAdvantage program has long been a favorite among many travelers, and for good reason. Its program is known for its:

Strong Earning Potential: Through its partnership with Chase, earning AAdvantage miles through co-branded credit cards can be very lucrative.
Partnerships: AAdvantage is part of the Oneworld alliance, giving members access to a vast network of international partners like British Airways, Cathay Pacific, and Qantas. This significantly enhances redemption opportunities.
Elite Status Benefits: American Airlines offers valuable elite status benefits, including upgrade certificates, lounge access, and priority services. Their Executive Platinum tier is highly regarded.
Redemption Sweet Spots: While redemption rates can be dynamic, there are still opportunities for excellent value, particularly for international business and first-class redemptions on partners.

My take: AAdvantage is a solid all-rounder. The redemption rates can be high on American’s own flights, but the partner redemptions can offer incredible value if you’re willing to do some digging. The elite benefits are robust, and the Oneworld alliance is a major draw for international travel.

Delta Air Lines (SkyMiles Program)

Delta’s SkyMiles program has undergone significant changes over the years, with a shift towards a more revenue-based earning and redemption model. It’s often a love-it-or-hate-it program. The arguments for Delta being "true blue" often center on:

Operational Excellence: Delta consistently ranks high in operational metrics like on-time performance and completion factor. For many, reliability is a key component of a "true blue" experience.
Customer Service: Delta is frequently lauded for its generally superior customer service, especially during irregular operations.
SkyTeam Alliance: Membership in the SkyTeam alliance provides access to a global network, though some argue its value is less than Oneworld or Star Alliance for certain redemption types.
Medallion Status Benefits: Delta’s Medallion status offers valuable benefits, including upgrades, though the upgrade system can be competitive.

My take: Delta’s strength lies in its operational reliability and customer service. The SkyMiles program itself can be frustrating for those seeking aspirational redemptions at fixed rates, as it's highly dynamic. However, if your priority is a smooth, hassle-free travel experience and excellent service, Delta might just be your "true blue" airline, even if the miles don't always stretch as far as you'd like.

United Airlines (MileagePlus Program)

United's MileagePlus program has also evolved, with a focus on dynamic pricing for award tickets. However, it retains strong appeal for many travelers due to:

Star Alliance Network: As a member of the Star Alliance, United offers access to a vast global network of airlines, including Lufthansa, Singapore Airlines, and Air Canada. This is a major advantage for international flyers.
Elite Status Benefits: United’s elite tiers provide valuable perks, including upgrade certificates, lounge access, and priority services. Premier Platinum and Premier 1K are highly sought after.
Card Partnerships: United has a strong partnership with Chase, offering several co-branded credit cards that can accelerate MileagePlus mile accumulation.
Direct Booking Advantages: Sometimes, booking directly with United can yield better availability or unique redemption opportunities.

My take: United's program is best for those who leverage the Star Alliance network for international travel or for those who can consistently earn and utilize upgrades. The dynamic pricing can be a double-edged sword – sometimes you can find incredible deals, other times redemptions can be prohibitively expensive. My experience with United's customer service has been mixed, but their operational performance is generally strong.

Southwest Airlines (Rapid Rewards Program)

Southwest operates a bit differently than the traditional hub-and-spoke carriers, with a unique loyalty program that many find exceptionally "true blue" for its simplicity and value, especially for domestic travel.

No Blackout Dates: This is a huge selling point. Southwest award flights are available as long as there are seats for sale.
Fixed Value Redemptions: Rapid Rewards points have a relatively fixed value, making it easier to understand how much your points are worth. This transparency is highly valued.
Companion Pass: The Southwest Companion Pass is arguably one of the best loyalty perks in the industry, allowing a designated companion to fly with you for just the cost of taxes and fees on any flight you book.
No Change or Cancellation Fees: Southwest is known for its flexible change and cancellation policies, even on paid tickets, which extends to award bookings.

My take: For domestic travel within the U.S., Southwest’s Rapid Rewards program is incredibly "true blue." The Companion Pass alone is worth pursuing if you fly with a partner or family member regularly. The transparency and ease of redemption are unmatched by many legacy carriers. However, their network is limited, so it’s not ideal for international travel.

JetBlue Airways (TrueBlue Program)

JetBlue aims for a more premium experience within the low-cost carrier space, and its TrueBlue program reflects this with a focus on simplicity and value.

Simple Earning and Redemption: TrueBlue points are earned based on fare type and can be redeemed for any available seat on JetBlue flights, with no blackout dates.
"Mint" Experience: JetBlue's premium "Mint" class offers a highly competitive lie-flat seat product on select transcontinental and Caribbean routes, which can be a great redemption value.
Partnerships: JetBlue has been expanding its partnerships, including with Hawaiian Airlines and now with American Airlines (though this partnership is evolving).
No Change or Cancellation Fees: Similar to Southwest, JetBlue generally offers flexible change and cancellation policies.

My take: JetBlue’s program is incredibly user-friendly. If you primarily fly on the East Coast or to certain Caribbean destinations, it can be a fantastic "true blue" option. The "Mint" product, when redeemed with points, can be a steal. The lack of blackout dates is a significant advantage, making it easy to plan trips.

Beyond the Big Carriers: Niche Airlines and Considerations

While the major U.S. carriers dominate the landscape, it’s worth considering smaller carriers or those with unique programs if they align with your travel patterns. For example:

Alaska Airlines (Mileage Plan): Alaska is often cited by points and miles enthusiasts as one of the most rewarding programs, particularly for its generous award charts and strong partnerships with airlines like Cathay Pacific and Japan Airlines. Their elite status benefits are also highly regarded. If you can fly from the West Coast, Alaska is definitely a contender for "true blue."
Hawaiian Airlines (HawaiianMiles): For travel to, from, or within Hawaii, HawaiianMiles can be a good option, especially if you can leverage their co-branded credit card or partner redemptions.

How to Determine Which Airline Is "True Blue" for YOU

The ultimate answer to "Which airline is true blue?" is deeply personal. It hinges on your individual travel habits, your spending patterns, and what you value most in a travel experience. Here’s a structured approach to help you figure it out:

Step 1: Analyze Your Travel Habits

Be honest about how and where you fly:

Frequency: How often do you fly annually? This determines if pursuing elite status is worthwhile.
Destinations: Do you mostly fly domestically, or do you have international travel aspirations? This will influence which alliances or airline networks are most beneficial.
Cabin Class: Do you typically fly economy, or do you aspire to fly in business or first class? This impacts the value you'll get from redemptions and elite benefits like upgrades.
Origin and Destination Airports: Your home airport and common travel destinations are critical. An airline with a strong hub in your home city or a significant presence in your frequent destinations will offer more convenience and earning opportunities.

Step 2: Evaluate Your Spending Habits

Consider how you can maximize miles and points through everyday spending:

Credit Card Usage: Do you have credit cards that earn transferable points (like Chase Ultimate Rewards or Amex Membership Rewards) or co-branded airline cards? Understanding your current credit card portfolio is key.
Other Spending: Do you frequently book hotels, rental cars, or shop online through specific portals?

Step 3: Research Loyalty Program Structures

Once you have a clearer picture of your habits, dive into the details of the programs that seem to align:

Earning Rates: How many miles do you earn per dollar spent or per mile flown? Are there significant elite bonuses?
Redemption Charts/Pricing: Look at how many miles are needed for the routes you commonly fly. Compare fixed award charts with dynamic pricing models.
Partner Airlines: Investigate the redemption options on partner airlines. This is often where the best value can be found.
Elite Status Requirements: If elite status is a goal, understand the spending and/or flying requirements to achieve different tiers.
Perks and Benefits: Carefully review the benefits associated with each elite tier. Do they align with what you value most (e.g., upgrades, lounge access, free bags)?
Fees and Restrictions: Pay close attention to change fees, cancellation fees, and any blackout dates or capacity controls for award travel.

Step 4: Calculate Potential Value

Try to quantify the value you might receive:

Valuing Miles: A common benchmark for U.S. domestic economy is around 1.2-1.5 cents per mile, and for international business/first, it can be 2-4 cents per mile or even higher. This is a rough estimate, as actual value varies wildly.
Quantify Elite Benefits: Estimate the monetary value of benefits like free checked bags, lounge access, or the estimated value of complimentary upgrades.
Compare Total Value: Sum up the potential value from earning, redemption, and elite benefits for different airlines and see which one offers the highest return for your specific travel patterns.

My Personal Philosophy on Being "True Blue"

For me, a "true blue" airline is one where the loyalty program feels like a genuine partnership. It's an airline that makes it relatively easy to earn miles, offers a reasonable number of redemption options without excessive fees or blackout dates, and provides tangible benefits that make my travel smoother and more enjoyable. It's also an airline whose customer service I can rely on when things go sideways.

I’ve found that focusing on transferable points currencies, like Chase Ultimate Rewards, Amex Membership Rewards, or Capital One Miles, provides the most flexibility. These points can often be transferred to multiple airline partners, allowing me to snag the best redemption deals across different alliances. This strategy reduces the risk of being locked into a single airline's program, which can devalue overnight.

However, there are times when a specific airline's program, like Southwest's Rapid Rewards with its Companion Pass, offers such a unique and powerful benefit that it warrants dedicating significant spending to that program. It’s about finding that sweet spot where simplicity, value, and practicality converge.

Ultimately, the term "true blue" implies a deep sense of trust and reliability. It's about an airline earning your loyalty not through complex, opaque systems, but through consistent delivery of value and a commitment to making your travel experience as positive as possible. It's the airline that makes you feel like you're getting something back for your loyalty, not just being subjected to a marketing scheme.

Frequently Asked Questions About "True Blue" Airlines

How do I know if an airline's loyalty program is truly valuable?

Determining the true value of an airline's loyalty program requires a bit of detective work and self-reflection. It’s not as simple as looking at the number of miles you can earn. You need to consider the entire ecosystem of the program. Start by assessing your own travel habits: where do you fly most often? What cabin class do you prefer? How much do you typically spend on flights? Answering these questions will help you identify airlines that are relevant to your travel needs.

Next, delve into the program's earning potential. This includes not just miles earned per dollar or mile flown, but also bonus opportunities through elite status, credit card partnerships, and promotions. A program that offers multiple avenues to earn is generally more valuable. Equally important, if not more so, is the redemption side. Are award seats readily available? Are the redemption rates reasonable, or do they fluctuate wildly? Are there exorbitant fees or taxes tacked onto award tickets? Some programs, like Southwest's Rapid Rewards, are praised for their transparency and lack of blackout dates, making their value more predictable. Others, like Delta's SkyMiles, are highly dynamic, which can sometimes lead to incredible deals but also frustratingly high redemption costs.

Finally, consider the elite status benefits. If you're a frequent flyer, these perks can significantly enhance your travel experience. Look at what benefits are offered at different tiers: complimentary upgrades, lounge access, priority services, extra baggage allowance. Do these benefits align with what you value most? For some, a guaranteed upgrade is paramount; for others, lounge access is a lifesaver. By systematically evaluating these components – earning, redemption, and elite benefits – in the context of your personal travel, you can begin to gauge the true value of an airline's loyalty program.

Why is it difficult to find award availability on some airlines?

The scarcity of award availability on certain airlines is a consequence of several factors, primarily driven by supply and demand dynamics within the loyalty program model. Airlines strategically limit the number of seats available for award redemption to ensure that they can maximize revenue from selling tickets at cash prices. This is particularly true for popular routes, peak travel times, and premium cabin classes (business and first class), where demand from both paying customers and award travelers is highest.

Furthermore, the rise of dynamic pricing has significantly impacted award availability. Unlike older, fixed award charts, dynamic pricing ties the number of miles required for a redemption directly to the cash price of the ticket. If a flight is in high demand and therefore expensive, the number of miles required to book it will also be high, making it seem as though award availability is scarce. Airlines also use partnerships with other carriers within alliances (like Star Alliance, Oneworld, and SkyTeam) to offer wider redemption options. However, the number of award seats made available to partners is often much smaller than what the airline makes available to its own elite members or for direct cash bookings. This can make redeeming miles on partner airlines particularly challenging.

To combat this, savvy travelers often employ strategies like booking far in advance, being flexible with their travel dates and times, and considering redemptions on partner airlines where availability might be better. Some airlines are also more generous with their award inventory than others. For instance, airlines like Southwest and JetBlue, which operate on a more simplified model and often have fewer blackout dates, can be easier for award redemptions, especially for domestic travel.

What are the biggest red flags to watch out for in an airline loyalty program?

When evaluating an airline loyalty program, certain red flags can signal that it might not be as "true blue" as it seems. One of the most significant red flags is **frequent and significant devaluations**. If an airline consistently increases the number of miles required for redemptions without a corresponding increase in earning opportunities or benefits, it’s a sign that the program’s value is eroding. This can be particularly frustrating if you’ve been diligently accumulating miles with the expectation of a certain redemption value.

Another major red flag is **extremely limited award availability**. If you consistently search for award tickets on popular routes and dates and find very few (or no) options, the program’s redemption value is severely diminished, regardless of how easy it is to earn miles. This is often exacerbated by **high fuel surcharges or hefty redemption fees** on award tickets. These additional costs can make redeeming miles less attractive than simply paying cash for a ticket, especially on international carriers.

**Opaque or constantly changing elite status requirements** can also be a cause for concern. If it’s unclear how to earn or maintain elite status, or if the requirements change drastically year after year, it makes it difficult for frequent travelers to plan and strategize. Lastly, **poor customer service, especially regarding loyalty program inquiries or issues**, is a significant red flag. A "true blue" program should be backed by a customer service team that is knowledgeable and helpful when it comes to managing your miles and benefits.

Are transferable points (like Chase Ultimate Rewards) better than airline miles?

The question of whether transferable points are "better" than airline miles is a nuanced one, and the answer largely depends on your travel goals and flexibility. Transferable points, such as those earned through Chase Ultimate Rewards, American Express Membership Rewards, Capital One Miles, and Citi ThankYou Rewards, offer a significant advantage in terms of **flexibility**. These points can be transferred to a variety of airline and hotel partners, allowing you to take advantage of the best redemption opportunities across different loyalty programs. This versatility is invaluable, especially when trying to book aspirational travel in premium cabins, where specific airline partners might offer better sweet spots for redemptions.

For example, if you have Chase Ultimate Rewards points, you can transfer them to United MileagePlus, Southwest Rapid Rewards, JetBlue TrueBlue, and several other airline partners. This means you aren't locked into one airline's potentially devaluing program. If United devalues its award chart, you can still use your Chase points for a better redemption with another partner. This flexibility can be a powerful hedge against program devaluations.

However, airline miles can sometimes offer **superior value for specific redemptions**. For instance, some airline partners have particularly favorable award charts for certain routes or cabin classes, allowing you to get a higher cents-per-point valuation than you might with transferable points. Additionally, many airlines offer special promotions or sales on award tickets that can be very lucrative. If you are a highly strategic flyer who knows exactly which specific routes and airlines offer the best value for their miles, directly accumulating airline miles might be beneficial. But for the average traveler seeking maximum flexibility and a buffer against devaluations, transferable points often represent a more robust and "true blue" approach to travel rewards.

How can I maximize my earnings with a "true blue" airline loyalty program?

Maximizing your earnings within a "true blue" airline loyalty program involves a multi-pronged approach, focusing on both flying and strategic non-flying spending. Firstly, **prioritize flying with your chosen "true blue" airline and its partners**. If you have elite status, ensure you are always crediting your flights to that program. Even without elite status, every mile counts towards your redemption goals.

Secondly, leverage **co-branded credit cards**. A "true blue" airline will likely have a co-branded credit card that offers a generous welcome bonus and everyday spending categories where you can earn bonus miles. For instance, if you fly American Airlines frequently, an AAdvantage co-branded card might offer bonus miles on American Airlines flights, everyday purchases, and even benefits like free checked bags. Use this card for as many of your regular expenses as possible, provided you can pay off the balance in full each month to avoid interest charges.

Thirdly, utilize **airline shopping portals and dining programs**. Most major airlines have online shopping portals where you can earn bonus miles by clicking through to retailers before making a purchase. Similarly, dining programs allow you to earn miles by linking your credit card to participating restaurants. These methods allow you to earn miles on purchases you would likely make anyway.

Finally, take advantage of **promotional offers**. Airlines frequently run promotions for bonus miles on specific routes, during certain travel periods, or for booking through their app or website. Keep an eye on these offers and strategically incorporate them into your travel plans. By consistently applying these strategies, you can significantly accelerate your mileage accumulation and get closer to those valuable redemptions faster.
