After months of crunching the numbers, here is how the complete outcomes panned out.

Total rankings and key takeaways

Delta’s seventh straight victory

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

Delta did not dominate in each class. The truth is, 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 energy throughout all the classes we analyzed, from the persistently robust, on-time airline operation it runs to the expertise clients have on the airport and of their seats.

Different prime takeaways from this yr’s outcomes:

• United Airways climbed to second place on this yr’s rankings. United improved in two key classes versus a yr prior: general reliability and passenger expertise, the place it completed third general. The Chicago-based service as soon as once more led our loyalty rankings, lifted by its Premier elite standing advantages and exhaustive accomplice community by means of the Star Alliance — and this does not even embrace the just lately introduced “Blue Sky” settlement with JetBlue that is set to start out rolling out later this yr.
• Two different airways made positive factors in our 2025 rankings: Southwest Airways and Hawaiian Airways. Notably, Southwest jumped two spots from final yr to 3rd place in our rankings after turning within the {industry}’s lowest cancellation price in 2024. It additionally maintained its lead on price and attain, thanks, partly, to the shortage of add-on charges it charged clients in 2024. However subsequent yr may very well be a really totally different story, given Southwest simply launched checked bag charges and, in current months, tightened up a few of its most customer-friendly insurance policies. Will these modifications trigger the airline to lose floor in subsequent yr’s rankings? Time will inform.
• American Airways noticed the largest year-over-year decline within the rankings. The truth is, it fell three spots to seventh general, topping solely a trio of finances airways. That fall got here because the airline has trailed prime 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 gadgets.
• Extremely-low-cost carriers Allegiant Air, Spirit Airways and Frontier Airways once more occupied the underside tier of our rankings. They have been hindered by their myriad of add-on charges, loyalty applications that did not measure up and fewer onboard options and facilities than their bigger rivals. May alternative lie forward? These airways are attempting, unveiling the whole lot from first-class seats and a loyalty glow-up at Frontier to new product choices at Spirit and a fast-growing fleet of brand-new planes at Allegiant.

Finest US airways for reliability

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

Airways confronted a tall job 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 ceaselessly a flight on the airline was delayed

• Bumps/involuntary denied boardings: How ceaselessly an airline bumped a traveler in opposition to their will on an oversold flight
• Baggage: How ceaselessly an airline mishandled a bit of checked baggage
• Wheelchairs/scooters: How ceaselessly an airline mishandled a mobility machine

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

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

Positive factors by Hawaiian and Southwest on this yr’s general rankings have been due, largely, to massive bounce backs in operational efficiency.

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

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

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

American and Alaska, the 2 lowest-ranked community carriers within the reliability class, have been hindered, partly, 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 gadgets. The service’s dealing with of wheelchairs was a part of what drew a lawsuit from the Biden administration final yr.

Spirit ranked lowest in that metric, misplacing a mean of two wheelchairs and scooters for each 100 it dealt with in 2024, in line with DOT information.

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

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

• Lounges: How widespread (and quite a few) an airline’s lounges are and the way inexpensive they’re to entry
• Household: How properly an airline caters to households touring with youngsters

Alaska Airways topped our outcomes centered on the journey expertise this yr, which have been weighted at 1 / 4 of the general rankings.

The Seattle-based service edged out Delta right here, delivering the most effective 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 youngsters.

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

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

Learn extra: Finest bank cards for lounge entry

Lounges stay entrance and middle in airways’ battle to win clients, 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 amenities that debuted in New York, Los Angeles and Boston.

Nonetheless, overcrowding stays a hurdle all through the {industry}, whilst extra golf equipment — and greater ones — have popped up. We have already seen Delta, United and Capital One tighten entry guidelines this yr, and it is a protected guess extra such modifications may very well be coming.

Onboard expertise

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

Look no additional than American’s current announcement that it’s going to be part of Delta, United and JetBlue in providing free web looking for its loyalty members in 2026.

Finest 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 focus of our “price and attain” class, which counted for 20% of our general rankings.

On this part, we analyzed a couple of components:

• 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 may fly for the cash you are paying, primarily based on monetary information from the Bureau of Transportation Statistics
• Ancillary charges: How a lot a typical passenger pays in bag and alter/cancellation charges

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

However Southwest could not get the identical elevate on this class subsequent yr and past after ending its long-standing “baggage fly free” coverage subsequent month and implementing a fundamental financial 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 fee to fly 1,000 miles rose barely in 2024 to $235.27 — up about 1% from 2023, properly beneath the extent of inflation.

As ordinary, the finances airways — led by Spirit and Frontier — led the way in which 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 simply a part of the whole 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 will possibly take you issues, too.

To guage 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 obtained rewarded for artistic routes like United’s flights to Marrakech, Morocco, and Alaska’s to La Paz, Mexico.

American led the way in which with its expansive home community, in line with DOT information. United led with its worldwide attain, as proven in information offered 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 greater 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 known as “out there seat miles”), you will see that United lapped its closest competitor by tens of billions of accessible seat miles due to its strong flight choices to far-flung locations in Australia, New Zealand, numerous African nations and extra.

American, in the meantime, relied closely on its energy 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

10. Frontier

Finest US airways for loyalty

Loyalty, after all, is a class we pay shut consideration to right here at TPG. Weighted at 25%, we analyzed a couple of components:

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

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

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

The service’s United MileagePlus program had essentially the most incomes and redeeming companions due to its participation within the expansive Star Alliance. It had essentially the most switch companions of any airline other than JetBlue, with which it was tied for having the third Most worthy loyalty foreign money.

There was exceptional consistency in our loyalty class when in comparison with final yr’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 yr, although.

• United just lately made it tougher to earn Premier elite standing.
• Southwest just lately devalued each its incomes and redeeming of Southwest Speedy Rewards factors.
• Alaska and Hawaiian are anticipated to launch a brand new joint loyalty program in August after merging final yr.
• Low-cost carriers are including extra beneficiant perks for frequent flyers, in hopes of engaging extra clients to their applications. Most notably, some Frontier Miles elite standing tiers just lately gained a companion go, and elite members will quickly be eligible for upgrades to its new first-class seats.
