Traveler’s guide to the best frequent flyer programs

Part of the Oneworld Alliance, Atmos Rewards, formerly known as the Alaska Mileage Plan is the best overall frequent flyer program.

The program has reasonable elite status requirements and is one of the few still publishing an award chart. This makes it easy for members to figure out how many miles they need for a flight. Award flights start at just 4,500 miles, and the free stopover allowance on one-way awards allows you to stretch your miles further by working multiple trips into one award redemption.

One of the best ways to redeem Atmos points is for long-haul business-class flights with partner airlines. Rates are reasonable compared to other loyalty programs. Flying from the West Coast to Japan, for example, costs just 50,000 miles each way in business class.

The merger with Hawaiian Airlines further enhances the program’s value, expanding its network to 141 direct destinations and over 1,200 global locations through Oneworld Alliance partners (although Hawaiian Airlines won’t be fully merged until Fall 2025). Members get benefits like free mileage transfers between accounts, streamlined booking across both airlines and Honolulu as a key hub, solidifying the Alaska Mileage Plan as one of the most valuable frequent flyer programs.

Alaska Airlines may be a domestic carrier, but thanks to its vast partnerships, it has an extensive route network spanning 1,000 destinations worldwide.

Co-brand and transfer partnerships: 3/5

Alaska Airlines has three credit cards: The Atmos™ Rewards Ascent Visa Signature® Credit Card (formerly the Alaska Airlines Visa Signature card), Atmos™ Rewards Summit Visa Infinite® Credit Card* and Atmos™ Rewards Visa Signature® Business Card* (formerly the Alaska Airlines Visa Business card). These cards provide opportunities to boost your Mileage Plan balance via credit card welcome bonuses and rewards for everyday spending.

Atmos Rewards is also a 1:1 transfer partner of Bilt Rewards, the only loyalty program that lets you earn points on fee-free rent payments. Bilt also runs periodic transfer bonuses, making it easy to stock up on Alaska miles quickly.

Ease of redeeming miles: 5/5

Alaska Airlines makes earning and redeeming miles easy by publishing an award chart that clearly states redemption rates (which start at 4,500 miles each way). Best of all, you can redeem most partner awards online, which is convenient when trying to research multiple partner flights on the same route.

Elite status requirements and benefits: 5/5

Atmos Rewards has one of the lowest elite status requirements of any frequent flyer program. It takes just 20,000 miles to earn baseline MVP status, which entitles you to useful perks like 25 percent elite bonus miles, first and premium class upgrades up to 48 hours before departure, priority check-in, a free checked bag, select lounge access and priority security lines at participating airports.

Mileage expiration: 5/5

Atmos points don’t expire, which means you don’t have to worry about losing out on your hard-earned miles because you didn’t get to redeem them before a specific date.

Airline reliability: 5/5

Alaska Airlines ranks above-average when it comes to on-time performance (OTP). According to the Bureau of Transportation Statistics (BTS), Alaska’s OTP as of April 2025 was 81.6 percent. This number is right at or slightly above-average, giving Alaska flyers peace of mind and reason to keep working towards their elite status goals.

The American Airlines AAdvantage program has several things going for it. For starters, American Airlines is part of the Oneworld Alliance, meaning you can use AAdvantage miles on partner carriers like Iberia, Japan Airlines, Qatar Airways and Finnair, to name a few.

One of the best “sweet spot” awards includes off-peak economy tickets to Europe for just 22,500 miles each way. Even luxury travel is reasonably priced, with the famous Qatar Airways Qsuites priced out at 70,000 miles each way to the Middle East.

American Airlines is also one of the only frequent flyer programs that counts nearly all rewards earned towards elite status. This includes purchases made through credit card spending, shopping portals and dining rewards. In other words, you could earn top-tier elite status with AAdvantage without ever stepping on a plane.

Network coverage: 4/5

American Airlines is one of the largest airlines in North America by passengers carried and serves over 350 airports in 60 countries. The airline is also part of the Oneworld Alliance, which serves over 900 destinations in 170 countries. This wide network provides members with plenty of opportunities to earn and redeem miles.

Co-brand and transfer partnerships: 3/5

American Airlines has five credit cards that let you earn miles via generous welcome bonuses and everyday spending. American AAdvantage is a 1:1 transfer option for those with certain Citi Strata credit cards. And you can transfer points from Marriott Bonvoy at a 3:1 ratio with a 5,000-mile bonus for every 60,000 points transferred.

Ease of redeeming miles: 4/5

American Airlines has dynamic pricing for its own flights but still publishes a partner award chart. Free flights start at just 7,500 miles and the program even has a handy tool to help you figure out how many miles you need for a partner flight. With most partner airlines bookable online, the AAdvantage program makes it easy to redeem miles for flights.

Elite status requirements and benefits: 4/5

American AAdvantage uses Loyalty Points to calculate elite status progress. Loyalty Points are earned via flights, credit card spending and other qualifying partnership activity. This makes status much more attainable, even if it takes 40,000 Loyalty Points to reach Gold status and 200,000 to achieve top-tier Executive Platinum.

Point expiration: 2/5

AAdvantage miles expire after 24 months of inactivity, which is less time than most other frequent flyer programs impose. However, because AAdvantage miles are extremely easy to earn, it may not be an issue for most members — and miles don’t expire at all if you have an AAdvantage credit card.

Airline reliability: 3/5

Airline reliability is important if you travel frequently with one airline. American Airlines performs below-average on on-time performance compared to other carriers. BTS reports 75.7 percent on-time performance between January and April 2025 (vs. 78.8 percent average for all airlines). This may be a hindrance for frequent fliers who want to minimize delays while traveling for work or leisure.

Turkish Airlines Miles&Smiles offers incredible sweet spot awards that are significantly cheaper than most other loyalty programs.

Miles&Smiles also offers one of the easiest ways to earn Star Alliance’s elite status. It takes just 25,000 miles to earn Classic Plus status, equivalent to Star Alliance Silver. There’s no revenue requirement, making earning status from cheaper flights possible.

Network coverage: 5/5

Turkish Airlines flies to 349 destinations in 130 countries, providing plenty of opportunities to redeem your miles for travel. In addition, Turkish Airlines is a Star Alliance member, a network that provides coverage in over 1,150 destinations in 189 countries worldwide.

Co-brand and transfer partnerships: 4/5

While Turkish Airlines doesn’t have any co-branded credit cards in the U.S., it makes up for it with numerous transfer partnerships. You can get Turkish miles easily through 1:1 transfers from Bilt Rewards, Capital One and Citi ThankYou. This makes Turkish Miles&Smiles incredibly accessible, so you can save up for your dream vacation faster.

Ease of redeeming miles: 5/5

Turkish Miles&Smiles still publishes an award chart, which makes it easy to see how many miles you’ll need for an award flight (and save up accordingly). Award flights start at just 4,500 miles each way, and sweet spots include 20,000-mile round-trip flights within the U.S. on United Airlines.

Turkish Airlines even allows online redemptions for these United flights, which is convenient if you don’t want to deal with long hold times. The only downside? Turkish Airlines’ website is notoriously glitchy.

Elite status requirements and benefits: 5/5

Turkish Airlines makes it fairly easy to earn elite status, requiring just 25,000 miles for Classic Plus status and 80,000 for top-tier Elite Plus. This status is valid for two years, and Classic Plus members receive practical perks like extra baggage, complimentary lounge access and business class check-in for domestic flights. Top-tier elites are spoiled with luxury perks like access to a special terminal entrance and passport counter at Istanbul International Airport (IST), seat upgrades, elite card gifting privileges and more.

Mileage expiration: 3/5

Turkish miles expire after three years of inactivity. It’s worth noting that point transfers aren’t considered a qualifying activity. However, if you earn or redeem miles during that period, your miles won’t expire. Furthermore, if you fly a Star Alliance carrier like United and credit your miles to Turkish Miles&Smiles, you’ll earn miles and qualifying activity that will keep them from expiring.

Airline reliability: 3/5

According to Cirium, a company that publishes aviation statistics, Turkish Airlines made the top 10 list regarding OTP in October 2024. The airline ranked 10th, with 77.44 percent OTP. This indicates significant improvements in flight punctuality since 2022, when the airline ranked 16th, with 64.08 percent OTP.

Air France and KLM’s joint Flying Blue program is part of the SkyTeam alliance and offers some of the cheapest international flights using miles. The program partners with five transferable rewards programs, making it easy to save up miles for an award flight.

Network coverage: 5/5

Flying Blue has a strong route network, thanks to its SkyTeam membership. SkyTeam serves over 1,000 destinations in over 160 countries worldwide. With Flying Blue miles, you’re not just earning and redeeming miles on KLM and Flying Blue: You can also fly Delta Air Lines, ITA Airways, Korean Air and Virgin Atlantic, to name a few.

Co-brand and transfer partnerships: 5/5

Flying Blue is one of the best loyalty programs when it comes to earning miles via co-branded cards and transfer partnerships. While the program offers just one co-branded credit card in the U.S. (the Air France KLM World Elite Mastercard®*), it offers a generous welcome bonus and benefits at a reasonable $89 annual fee.

But where Flying Blue shines is in its transfer partnerships: The program is a 1:1 transfer partner of every major rewards program: Amex Membership Rewards, Bilt Rewards, Capital One, Chase Ultimate Rewards, Citi ThankYou Rewards and Wells Fargo Rewards. These partnerships make Flying Blue miles incredibly accessible and easy to earn.

Ease of redeeming miles: 2/5

While earning Flying Blue miles is easy, redeeming them can be challenging. Not all transfer partner flights are bookable online, so you may have to call the airline for some bookings. Flying Blue currently does not have an award calculator or chart, but it has a list that shows how many miles you’ll need for a flight.

The program also offers deep discounts on award flights through monthly Promo Rewards. Considering long-haul flights between the U.S. and Europe start at just 15,000 miles round-trip, this is an excellent program for stretching your rewards further.

Elite status requirements and benefits: 4/5

FlyingBlue has four elite status levels, starting with Explorer and going up to Ultimate. Members have to earn Experience Points (XP) for status, which is calculated based on flight distance, cabin and elite status. Members can earn between two and 60 XP, depending on these factors.

Furthermore, you can earn XPs by buying carbon credits, donating to charity or via the Flying Blue credit card, which offers 20 XP on every account anniversary and an additional 40 XP after you spend $15,000 or more on purchases within the anniversary year — that’s 60 percent of the way to Silver status.

Silver status requires earning 100 XP and provides benefits like free checked bags and seat selection, priority check-in, complimentary free checked bag on SkyTeam flights and 6 miles per Euro spent on flights.

Top-Tier Ultimate status requires earning 900 UXP (Ultimate Experience Points) in a year, earned entirely from Air France or KLM flights. These elites receive ultra-luxury perks like a dedicated Platinum Service Line, 8 miles per Euro spent on flights, Sky Priority access at airports, lounge access with guest privileges and more.

Point expiration: 2/5

Unfortunately, simply earning and redeeming miles won’t keep your Flying Blue miles from expiring after two years. You have to travel at least once every two years on Air France, KLM or a partner airline flight. Mileage expiration is waived if you’re a Flying Blue Silver, Gold or Platinum member during this period. You can also avoid mileage expiration by making a purchase with a co-branded credit card once every two years.

Airline reliability: 4/5

According to OAG, a travel data provider, KLM and Air France rank 57th and 85th, respectively, in terms of OTP in December 2024. Air France achieved 68.49 percent OTP while KLM reached 74.69 percent. While this isn’t going to be a priority for U.S.-based travelers, it’s useful information to have when traveling abroad.

Delta SkyMiles is a standout program for travelers who value flexibility and a range of redemption options. As part of the SkyTeam alliance, Delta offers access to a vast network of over 1,000 destinations worldwide. The program is particularly appealing for domestic travelers, as Delta has a strong presence in major U.S. hubs like Atlanta, Detroit and Minneapolis.

One of the key strengths of Delta SkyMiles is its dynamic pricing model, which allows members to redeem miles for flights at any time without blackout dates. While this can lead to higher redemption rates for premium cabins, it also means you can often find last-minute award availability. Additionally, Delta offers “Pay with Miles” options, allowing you to offset the cost of a ticket with a combination of cash and miles.

Delta’s elite status program is also highly regarded, offering perks like complimentary upgrades, priority boarding and waived baggage fees. Earning status is straightforward, with Medallion Qualification Miles (MQMs) and Medallion Qualification Dollars (MQDs) calculated based on flights and spending.

Network coverage: 5/5 

Delta’s extensive domestic and international network, combined with its SkyTeam alliance partnerships, makes it easy to earn and redeem miles for award flights around the globe.

Co-brand and transfer partnerships: 4/5

Delta offers several co-branded credit cards, including the Delta SkyMiles® Gold American Express Card and Delta SkyMiles® Platinum American Express Card, which provide opportunities to earn miles through everyday spending and welcome bonuses. Delta is also a transfer partner of American Express Membership Rewards, making it easy to top up your SkyMiles balance.

Ease of redeeming miles: 4/5 

Delta’s dynamic pricing model ensures that award seats are available on most flights, though redemption rates can vary widely. The ability to use miles for upgrades, seat selections and even Delta Vacations packages adds to the program’s flexibility.

Elite status requirements and benefits: 4/5 

Delta’s elite status program is one of the most rewarding in the industry, with benefits like complimentary upgrades, priority boarding and lounge access. However, the MQD requirement is a hurdle, as it requires a minimum spending on Delta flights or co-branded credit cards.

Mileage expiration: 5/5

Delta SkyMiles do not expire, making them a sound option for travelers who may not fly frequently but still want to accumulate miles over time.

Airline reliability: 4/5 

Delta consistently ranks as one of the most reliable U.S. airlines, with strong OTP and customer service. According to Cirium, Delta achieved an OTP rate of 83.46% in 2024, making it a dependable choice for frequent flyers.

Delta SkyMiles is an excellent choice for travelers who prioritize flexibility, a strong domestic network and valuable elite status perks. While the dynamic pricing model can lead to higher redemption costs, the program’s ease of use and lack of blackout dates make it a top contender for frequent flyers.

The Southwest Rapid Rewards program is ideal for families and domestic travelers who want a straightforward loyalty program that offers practical rewards.

Members earn points based on the fare type and cost. In addition to making their way toward higher status, members can qualify for the Southwest Companion Pass after earning 135,000 points. Families who can manage to earn two or more of these Companion Fares can cut the cost of family travel in half. Points earned from Southwest credit card sign-up bonuses also qualify for the Companion Pass, making it incredibly attainable.

Network coverage: 2/5

Southwest has a limited route network compared to other airlines, but it’s a solid option for domestic travelers. The airline flies to over 100 destinations in 42 states, Puerto Rico, Mexico, Central America and the Caribbean. While its route network is limited, it does serve key markets at competitive fares.

Co-brand and transfer partnerships: 4/5

There are five Southwest Rapid Rewards credit cards to choose from, providing ample opportunity to rack up points. Southwest is also a 1:1 transfer partner of Chase Ultimate Rewards, so members can transfer rewards earned from cards like the Chase Sapphire Preferred® Card and Chase Sapphire Reserve® to their Rapid Rewards account. Marriott points also transfer 3:1 to Southwest Rapid Rewards.

Ease of redeeming miles: 4/5

Southwest airlines makes it easy to redeem points for flights. There is no award chart, but points are worth around 1.3 cents each. Because Southwest Airlines does not offer first-class seating, you won’t be able to use your Rapid Rewards points for first-class flights. However, the simplicity of the program more than makes up for it. You can redeem your points on any available flight without worrying about blackout dates or restrictions, making it easy to maximize the value of your rewards.

Elite status requirements and benefits: 3/5

Southwest Rapid Rewards has two elite status tiers and they’re fairly attainable. It’s worth noting that Southwest doesn’t have a premium cabin. So, elite status with this frequent flyer program doesn’t offer the same level of perks and luxury.

However, the program has one major advantage that makes earning status worthwhile: the Southwest Companion Pass. Reserved for top-tier elites who complete 100 flights or earn 135,000 points in a calendar year, it allows you to designate a companion who then flies for just the cost of taxes and fees. The Companion Pass can save you hundreds or even thousands of dollars on airfare, making it one of the best elite status perks out there. The best part? The welcome bonus from the Southwest credit cards counts towards the 135,000-point requirement.

Point expiration: 5/5

Southwest points do not expire as long as your account remains open and in good standing. That’s a significant feature, especially when you factor in the ease of earning and redeeming points.

Airline reliability: 3/5

By 2024, Southwest has improved its OTP by nearly two percentage points. According to Cirium, the airline has achieved an OTP of 77.77%. Placing Southwest in fifth place among airlines. This makes it a decent frequent flyer program with a consistently reliable airline.

The United MileagePlus program is popular among domestic frequent flyers seeking valuable elite perks and a large partner network.

United Airlines is part of the Star Alliance, which includes 25 airlines serving over 1,200 airports worldwide. While award flights are priced dynamically (i.e. based on demand and paid fares), the program can offer excellent value on short-haul and off-peak season travel. Unlike Star Alliance airlines like Lufthansa, United doesn’t impose fuel surcharges on award flights. So, even if you redeem more miles, you might save money by redeeming United miles.

Travelers also remain loyal to United because of its attainable elite status requirements. United allows members to earn Premier Qualifying Points (PQP) by spending on select United credit cards. Once they’ve earned status, United elite members can enjoy perks like complimentary seat upgrades, free checked bags and access to better award availability.

Network coverage: 4/5

United has a large network, with hubs in major cities domestically and abroad. As of 2025, United served 350 destinations on its own and over 1,290 across 200 countries through the Star Alliance network.

Co-brand and transfer partnerships: 5/5

United MileagePlus has several co-branded credit cards issued by Chase, catering to different types of travelers. United is also a 1:1 transfer partner of Bilt Rewards and Chase Ultimate Rewards, providing plenty of opportunities to top off your balance quickly for an award flight. Plus, United is a 3:1 transfer partner of Marriott Bonvoy.

Ease of redeeming miles: 3/5

United no longer publishes an award chart. Instead, it has dynamic pricing, which makes redemption rates unpredictable. That being said, the cheapest award flights start at around 4,500 miles and increase to six figures depending on the fare and cabin.

Elite status requirements and benefits: 4/5

United MileagePlus has four elite status tiers, with numerous paths to get there. Base-level Premier Silver status requires 15 Premier Qualification Flights (PQF) and 5,000 Premier Qualification Points (PQP). Alternatively, you can earn this status level by earning 6,000 PQP instead.

Premier Silver elites get useful perks like one free checked bag, upgrades to Economy Plus, priority boarding and 7X miles earned on every flight. Top-tier Premier 1K status can also be rewarding, with three checked bags, Economy Plus upgrades at booking for you and up to eight companions, 11X miles on every flight and more. MileagePlus Premier 1K status requires 60 PQF and 22,000 PQP or 28,000 PQP.

Because you can earn PQPs from the United Quest℠ Card* and United Club℠ Infinite Card*, earning status with United MileagePlus is much easier.

Point expiration: 5/5

United MileagePlus miles don’t expire, making them ideal for folks with trouble earning and rapidly redeeming miles.

Airline reliability: 5/5

United Airlines ranks slightly above average when it comes to airline reliability. According to Cirium, in November 2024, United achieved an OTP of 80.12%, securing second place among airlines, although this marked a slight decline from 82.88% the previous month. Travelers can generally rely on United for punctual service, making it a solid choice for those prioritizing reliability.
