Total rankings and key takeaways

Delta’s seventh straight victory

If there is a theme in Delta’s seventh straight 12 months of topping our airline rankings, it is that consistency issues.

Delta did not dominate in each class. Actually, there have been loads of areas the place different airways scored increased, from affordability to how far its SkyMiles go in comparison with different airways’ award foreign money.

What put Delta excessive in 2025 was its power throughout all the classes we analyzed, from the persistently robust, on-time airline operation it runs to the expertise prospects have on the airport and of their seats.

Different high takeaways from this 12 months’s outcomes:

• United Airways climbed to second place on this 12 months’s rankings. United improved in two key classes versus a 12 months prior: general reliability and passenger expertise, the place it completed third general. The Chicago-based provider as soon as once more led our loyalty rankings, lifted by its Premier elite status benefits and exhaustive companion community via the Star Alliance — and this does not even embody the not too long ago introduced “Blue Sky” agreement with JetBlue that is set to begin rolling out later this 12 months.
• Two different airways made positive factors in our 2025 rankings: Southwest Airways and Hawaiian Airways. Notably, Southwest jumped two spots from final 12 months to 3rd place in our rankings after turning within the {industry}’s lowest cancellation charge in 2024. It additionally maintained its lead on price and attain, thanks, partially, to the dearth of add-on charges it charged prospects in 2024. However subsequent 12 months might be a really completely different story, given Southwest just launched checked bag fees and, in current months, tightened up a few of its most customer-friendly insurance policies. Will these adjustments trigger the airline to lose floor in subsequent 12 months’s rankings? Time will inform.
• American Airways noticed the largest year-over-year decline within the rankings. Actually, it fell three spots to seventh general, topping solely a trio of finances airways. That fall got here because the airline has trailed high rivals Delta and United in profitability of late and seemingly been in catch-up mode to these carriers concerning high-end choices like business-class seats, cabin options and lounges. American’s new Flagship Suites ought to assist, however the airline additionally scored poorly on its dealing with of luggage and mobility units.
• Extremely-low-cost carriers Allegiant Air, Spirit Airways and Frontier Airways once more occupied the underside tier of our rankings. They had been hindered by their myriad of add-on charges, loyalty packages that did not measure up and fewer onboard options and facilities than their bigger rivals. Might alternative lie forward? These airways try, unveiling every little thing from first-class seats and a loyalty glow-up at Frontier to new product offerings at Spirit and a fast-growing fleet of brand-new planes at Allegiant.

Greatest US airways for reliability

Since attending to your vacation spot safely and on time are (in that order) two of probably the most elementary parts of journey, reliability carries the strongest weight of our 4 classes: 30% of the general rankings.

Airways confronted a tall process in 2024 when airports crammed up with record-setting crowds, together with what proved, on the time, to be every of the ten busiest days ever at U.S. airports.

Our reliability rankings keep in mind:

• Timeliness: How regularly a flight on the airline was delayed
• Cancellations: How regularly a flight on the airline was canceled
• Bumps/involuntary denied boardings: How regularly an airline bumped a traveler in opposition to their will on an oversold flight
• Baggage: How regularly an airline mishandled a bit of checked baggage
• Wheelchairs/scooters: How regularly an airline mishandled a mobility gadget

Delta’s reliability power in comparison with its friends in 2024 got here regardless of a rough week last July, throughout which the airline canceled 1000’s of flights over a number of days attributable to a world IT outage at cybersecurity agency Crowdstrike.

However inside days, the airline received again to operating the on-time operation it is traditionally been celebrated for.

Positive aspects by Hawaiian and Southwest on this 12 months’s general rankings had been due, largely, to large bounce backs in operational efficiency.

2024 noticed Hawaiian regain its hallmark reliability, a 12 months after the tragic wildfires in Maui made cancellations unavoidable.

For Southwest’s half, its industry-leading cancellation charge was 17% higher than 2023 and helped quell reminiscences of its high-profile vacation meltdown in 2022.

Industrywide, the cancellation charge ticked up in 2024 from 2023 however was worlds higher than 2022, when chaotic scenes at airports had been rampant.

7. Alaska Airways

8. Spirit Airways

9. American Airways

10. Frontier Airways

American and Alaska, the 2 lowest-ranked community carriers within the reliability class, had been hindered, partially, by decrease marks when it got here to mishandled baggage, wheelchairs and scooters.

American additionally completed close to the underside of the pack when it got here to dealing with mobility units. The provider’s dealing with of wheelchairs was a part of what drew a lawsuit from the Biden administration final 12 months.

Spirit ranked lowest in that metric, misplacing a median of two wheelchairs and scooters for each 100 it dealt with in 2024, based on DOT knowledge.

Frontier improved its general rating by 12% over final 12 months’s report however maintained its perennial last-place end when it got here to reliability.

It additionally had an astonishingly excessive charge of passengers bumped in comparison with its rivals.

Supply: DOT knowledge

To be clear: Getting bumped on Frontier stays statistically unlikely, at 0.02% of passengers who boarded flights during the last two years. But, throughout that point, a passenger boarding a flight on Frontier was 25,000 instances extra more likely to be bumped than on Delta.

Greatest US airways for the journey expertise

Our expertise class evaluates airways on a number of elements that may make an enormous distinction in how pleasant a visit is with a specific airline.

On this class, we examined:

• Cabin options: What you may expertise on board, together with Wi-Fi, seat pitch/width and inflight leisure
• Lounges: How widespread (and quite a few) an airline’s lounges are and the way reasonably priced they’re to entry
• Household: How nicely an airline caters to households touring with kids
• Buyer satisfaction: The speed at which passengers complain to the DOT in regards to the provider

Alaska Airways topped our outcomes targeted on the journey expertise this 12 months, which had been weighted at 1 / 4 of the general rankings.

The Seattle-based provider edged out Delta right here, delivering one of the best marks of any airline when it got here to family-friendly insurance policies, which evaluated options like assured seats collectively, free lounge entry for youngsters and early boarding for vacationers with children.

Alaska trailed solely Southwest when it got here to the bottom charge of buyer complaints filed with the DOT.

Moreover, it topped our metrics targeted on the worth you’d get, on common, via a paid annual lounge membership: For $795, an Alaska Airways Lounge+ enrollment will get you entry to 61 home golf equipment, together with Alaska’s branded lounges, American Airways Admirals Golf equipment and a handful of United Membership services, amongst others.

We must always word, all three of the above airways — and their rivals — provide complimentary methods to achieve lounge entry via sure cobranded bank cards.

Learn extra: Best credit cards for lounge access

Lounges stay entrance and middle in airways’ battle to win prospects, and 2024 introduced us among the swankiest golf equipment but within the U.S. — most notably Delta’s all-new assortment of business-class-only Delta One Lounge services that debuted in New York, Los Angeles and Boston.

Nonetheless, overcrowding stays a hurdle all through the {industry}, at the same time as extra golf equipment — and greater ones — have popped up. We have already seen Delta, United and Capital One tighten entry guidelines this 12 months, and it is a protected guess extra such adjustments might be coming.

Onboard expertise

One different facet of the journey expertise the place Alaska was not a number one airline: economic system cabin options. JetBlue led the best way there, helped by continued power in its core product that options its signature seatback screens, free Wi-Fi and extra beneficiant legroom.

Nevertheless, Delta and United had been an in depth second and third, due to an onboard arms race, of sorts, involving vital investments in inflight leisure, Bluetooth connectivity and free Wi-Fi.

2. Delta

3. United

4. Hawaiian

5. American

6. JetBlue

7. Southwest

8. Allegiant

10. Frontier

Wanting forward, we anticipate to see improved scores throughout the board for the journey expertise airways provide. That is as a result of carriers are making vital investments in onboard tech, slashing or totally reducing Wi-Fi charges and upgrading planes with higher seats and premium merchandise.

Look no additional than American’s current announcement that it’ll be a part of Delta, United and JetBlue in providing free internet browsing for its loyalty members in 2026.

Greatest US airways for price and attain

What number of locations can an airline take you — and the way a lot will a visit hit your pockets?

That is the main target of our “price and attain” class, which counted for 20% of our general rankings.

On this part, we analyzed a number of elements:

• Route community: What number of home airports an airline served, on common, domestically (weighted 80%) and internationally (weighted 20%)
• Affordability: How far (in distance) you’ll be able to fly for the cash you are paying, primarily based on monetary knowledge from the Bureau of Transportation Statistics
• Ancillary charges: How a lot a typical passenger pays in bag and alter/cancellation charges

Southwest led the best way on this class, due to its huge home community and — sarcastically — the minuscule add-on charges it charged prospects in 2024 in comparison with its rivals.

However Southwest could not get the identical carry on this class subsequent 12 months and past after ending its long-standing “baggage fly free” coverage subsequent month and implementing a primary economic system fare.

Value

When it got here to affordability, we judged airways on how a lot they charged passengers, on common, to fly 1,000 miles, utilizing fare income reported by carriers to the Bureau of Transportation Statistics in 2024.

Industrywide, the associated fee to fly 1,000 miles rose barely in 2024 to $235.27 — up about 1% from 2023, nicely beneath the extent of inflation.

As typical, the finances airways — led by Spirit and Frontier — led the best way in affordability primarily based on the fare alone.

However as any traveler who has flown aboard low-cost airways is aware of, the bottom fare is barely a part of the entire price you pay to fly.

Whereas the “Huge Three” airways (American, Delta and United) collected a whopping $3.9 billion in checked bag charges in 2024, the finances carriers far exceeded their legacy rivals by way of the common charges passengers paid per journey.

Attain

In fact, price is not the one issue when selecting an airline. The place it could possibly take you issues, too.

To judge airways’ route networks, we evaluated what number of cities, on common, they served every month. We checked out home attain and, for the primary time in 2025, factored in worldwide route networks, too — which means airways received rewarded for artistic routes like United’s flights to Marrakech, Morocco, and Alaska’s to La Paz, Mexico.

American led the best way with its expansive home community, based on DOT knowledge. United led with its worldwide attain, as proven in knowledge supplied to TPG from aviation analytics agency Cirium.

One focal point: Although it could seem like United narrowly beat American on worldwide community, it flew a lot farther general and with far larger planes.

Should you add up what number of whole seats United flew internationally and multiply it by the variety of miles these seats traveled (a key {industry} metric referred to as “accessible seat miles”), you may see that United lapped its closest competitor by tens of billions of obtainable seat miles due to its sturdy flight choices to far-flung locations in Australia, New Zealand, varied African nations and extra.

American, in the meantime, relied closely on its power in Mexico, the Caribbean and Central and South America.

This is how the complete price and attain class rankings shook out:

1. Southwest

2. American

3. United

4. Delta

5. Spirit

6. Alaska

7. Allegiant

8. Hawaiian

9. JetBlue

10. Frontier

• Frequent flyer program: How rewarding an airline’s loyalty program relies on TPG’s valuations, elite standing, cobranded bank cards, companion airways and expiration policies
• Award availability: How simple and precious it’s to redeem your rewards throughout widespread journey instances

Although American Airways AAdvantage miles and Alaska Airways Mileage Plan miles tied as probably the most precious loyalty foreign money of any U.S. airline in our newest month-to-month valuations, it was really United that gained our loyalty class.

Serving to United was its relative power throughout most of the classes we analyzed.

The provider’s United MileagePlus program had probably the most incomes and redeeming companions due to its participation within the expansive Star Alliance. It had probably the most switch companions of any airline apart from JetBlue, with which it was tied for having the third most beneficial loyalty foreign money.

There was exceptional consistency in our loyalty class when in comparison with final 12 months’s outcomes:

1. United

2. Alaska

3. American

4. Delta

5. JetBlue

6. Southwest

7. Hawaiian

8. Spirit

9. Frontier

10. Allegiant

The one change was Alaska and its Mileage Plan program leapfrogging American’s AAdvantage program.

There are alternatives for extra motion to come back over the following 12 months, although.

• United not too long ago made it tougher to earn Premier elite standing.
• Southwest recently devalued each its incomes and redeeming of Southwest Fast Rewards factors.
• Alaska and Hawaiian are anticipated to launch a new joint loyalty program in August after merging final 12 months.
• Low-cost carriers are including extra beneficiant perks for frequent flyers, in hopes of engaging extra prospects to their packages. Most notably, some Frontier Miles elite standing tiers not too long ago gained a companion pass, and elite members will quickly be eligible for upgrades to its new first-class seats.
