8 Most Popular US Airlines In 2026, Ranked Worst To Best

Getting angry about an airline's customer experience is kind of funny when you think about it. Yes, travel has become prohibitively expensive for many, but just 100 years ago, these journeys may have taken a week or even more, depending on where you're going. A few hours of mediocre food, sore knees, and a sassy flight attendant should be a small price to pay for the privilege of a leisurely weekend in the Caribbean or a fortnight in Singapore.

Still, airline satisfaction is one of the most fiercely debated aspects of travel. Everyone has an opinion and it's hard to sway them otherwise. It can be tough to put together a real sense of which carrier is the best without flying on all of them — so you're basing it solely on anecdotal experience. 

This is why JD Power has published its annual 2026 North America Airline Satisfaction Study, ranking each airline on the continent based on a survey of almost 11,000 passengers. The survey was designed to measure passenger satisfaction, prompting participants to score the airline they flew with on seven aspects of the experience: airline staff, digital tools, ease of travel, level of trust, on-board experience, pre- and post-flight experience, and the value for the price paid. For our ranking, we've taken the average position for each airline in all three categories. Some airlines only compete in economy, which is their only score. We've also excluded Spirit Airlines, which was shut down in May 2026 (after the report was published).

We also compared JD Power's rankings with other statistics pulled from The Points Guy, Travel+Leisure, The U.S. Department of Transportation, and Cirium. While there are still definitely elements of subjectivity and experience influencing the results, the survey represents a solid look at the current airline experience in the U.S.

The first (i.e. "worst") on our list is Frontier Airlines. This isn't a big surprise, no matter how cute the animals on the tail are. The Denver-based airline is a budget set-up, operating in 120 destinations across the U.S., Caribbean, Mexico, and Central America. The carrier has been close to the bottom since 2020, when it just barely pipped Spirit Airlines. Perhaps it's no wonder that Spirit is no longer in operation, which is why it was excluded on our list here.

An ultra-low-cost carrier finishing last is nothing out of the ordinary. Passengers on Reddit remain frustrated by the add-on fees for baggage, check-ins, seat selection, and just about everything else. Many travelers still value the budget airline setup since it allows them to travel affordably provided they also travel light. If Frontier's placement was solely based on misdirected anger, one could overlook it. But the airline's other disadvantages add up for a far bigger obstacle.

The Points Guy's (TPG) comprehensive airline report for 2026 also placed Frontier dead last. But instead of using customer satisfaction, it dove into general statistics from aviation analytics firm Cirium. Frontier did have the cheapest tickets in the market, but was also the most unreliable airline. According to TPG, Frontier had the worst "on-time percentage" and was a whopping 88,000 times more likely to bump a passenger off a flight compared to Delta. The stats don't look good for Frontier, and with below-average score for both short- and long-haul flights by JD Power, it has a long way to go in making it up to the customers. But there is a glimmer of hope: The airline is making five big changes in 2026, including a first class cabin, so maybe that will usher in some positivity.

United's placement here should be a severe disappointment to its leaders. It's regarded as one of the world's largest airlines, flying about 175 million passengers to over 350 destinations around the world each year. In short, this is not a budget carrier scrounging for baggage fees. Yet, the airline managed to finish below the segment average for both short- and long-haul flights by JD Power.

Frustratingly, JD Power hasn't published the specific stats for each of its criteria, so the exact trigger points for passengers aren't clear from that survey. Regardless, they've been consistently chastised across the board — but maybe that'll change after United launches its beds in economy. Looking to other outlets to fill in the knowledge gaps, the placement gets even murkier. In the same aforementioned TPG report, United came in second and was just a whisker away from taking the top spot statistically. The only truly poor category it registered was in reliability, where its poor history of baggage handling let it down. 

According to the U.S Department of Transportation (DOT), United had a 0.66% rate of mishandled bags per 100 passengers. Granted, this rate is the worst one compared to other airlines in this DOT report. Still, even if every one of the 10,914 respondents to the JD Power survey had traveled with United, that would mean only around 72 of them would have had a mishandled bag. Considering all of this, it's worth taking surveys like this with a pinch of salt. It's important to note that both TPG and JD Power used different samples and data for their respective surveys, so United's customer satisfaction may just come down to who you're talking to.

American Airlines leadership may also be disappointed to see the company so far down in the pecking order. Also similar to United, it ranked below the segment average across all cabin classes by JD Power. It also scored below United in both first/business class and premium economy categories, only scraping past thanks to a 16-point lead in the basic economy segment.

TPG ranked American Airlines as the fifth best U.S. carrier of 2026, a full three spots below United. It had a similar (and technically higher) number of mishandled bags compared to United, but the publication also noted that American also handled more bags in general. It also had the worst cancellation record across the board and a fairly average on-time record. In fact, one of its primary saving graces with TPG was its loyalty program, AAdvantage, which is one of the best ways to use points to travel the world for free. But that's not one of the metrics JD Power used.

Without the individual breakdowns JD Power used, it's hard to see exactly which criteria was prioritized when they were culling their data. There is evidence that would arguably put American below United on many other metrics besides luggage mishandling, so American may actually be happier with its placement than many would assume. Still, the rankings don't bode well for an airline of American's size and reach.

Allegiant Air is looking like something of an outlier in the listings. Another one of the ultra-low-cost carriers, the Las Vegas-based airline has gone from strength to strength since it went bankrupt and faced a full restructuring a little over 25 years ago. Now, it features above the average score on JD Power's ranking for 2026.

As a budget carrier, it only features in the economy segment of the scoring, which should be factored in to an extent, but the statistics back the airline up in many of the most important metrics, too. TPG's ranking placed it seventh overall, noting that its lower placement primarily comes from the lack of perks that the larger airlines boast, as well as a tiny reach. This isn't too surprising, since its main M.O. is connecting smaller cities with major travel destinations. Where it shone brighter than any was in reliability — a true rarity for budget airlines. The little airline ranked best overall for reliability with the lowest cancellation rate of any airline. 

In many ways, this is the most consistent ranking we've found across the board. After all, if a budget airline simply does what it says, who isn't going to be happy? The airline takes passengers from neglected airport cities and gets them where they want to go. Better yet, it does it on time, doesn't kick them off, and keeps the fees in line with the market.

Alaska Airlines is where the ranking starts getting seriously competitive. The Seattle-based carrier placed inside the top four in every cabin JD Power measured, finishing third in first/business class, second in premium economy, and fourth in basic economy. It is also comfortably slotted above the segment average in every category.

And while some of the placements of other airlines in the list have been a little at odds with other surveys out there, Alaska Air Group's own numbers do plenty to support that customer satisfaction. TPG ranked the combined Alaska and Hawaiian operation (Hawaiian was acquired by Alaska Air Group in 2024) the fourth-best in the country, including second for its overall travel experience, third for loyalty, and fourth for reliability. Even more impressively, recent Cirium data found that Alaska Air Group was the most punctual major airline in North America during the first half of 2026. Topping everything off is its stellar loyalty program. The Atmos Miles program has some incredible value, and this year seems to be no different, since it won the Best Innovation award in Airline Loyalty category by the 2026 TPG Awards.

That makes Alaska Airlines a fairly non-contentious placement on JD Power's list. It doesn't have the immense route network of Delta, United, or American, but it's doing an excellent job with the network it has. The merger with Hawaiian expands its reach and as it's adding new long-haul international routes that push it beyond its West Coast stronghold, maintaining the same level of satisfaction will be the real test. Being one of the airlines that are changing the game for travelers' Wi-Fi experiences certainly doesn't hurt their reputation either.

The New York-based carrier, JetBlue, finished third on JD Power's list in both economy and premium economy, but absolutely cleaned up at the front of the plane — taking first place in first/business class category. It scored nine points ahead of nearest competitor and crowd-favorite, Delta, and a super impressive 42 points above the segment average, helping it secure third place in their combined ranking.

On the other hand, TPG placed JetBlue sixth overall in its 2026 ranking, behind every legacy carrier as well as Southwest and Alaska. JetBlue still seems to shine in actual onboard experience, and TPG considers it the best U.S. airline for economy cabin features — it also has the most legroom of any U.S. airline in economy. This is something that speaks to its strong business class result in the JD Power survey, too, with its Mint seat being regarded as one of the best in the market. But reliability was singled out as one of its major weaknesses. Cirium's numbers for the first half of 2026 (via Travel+Leisure), show an on-time arrival rate of just 74.1%, which was well behind Alaska, Delta, United, and American. 

We do have one theory as to why JetBlue performs so much better in a customer satisfaction survey than in a statistics-heavy ranking. Flights arriving late should obviously upset passengers, but once they're actually onboard, JetBlue offers an economy experience that can feel a significant step above its competitors. Throw its highly-regarded Mint business class seats into the mix and it becomes much easier to understand how the airline ranks this high. If this list is teaching you anything, it should be that general statistics and individual experience are very different things.

If you wanted the safest answer to the question of which is America's "best" airline, Delta would probably be it in most cases. Typically finishing on top of these lists (and proudly announcing it too), the Atlanta-based giant came agonizingly close to sweeping JD Power's survey, finishing second in first/business class, first in premium economy, and second in basic economy. Its 750-point premium cabin score was only nine points behind JetBlue, while Southwest beat it in economy by just three points.

This is also one carrier where the customer opinions and pure statistics are almost perfectly aligned. TPG also named Delta the best airline in the United States for a whopping eighth consecutive year, placing it second for reliability and first for the overall travel experience. Cirium's more recent figures tell much the same story: 81.74% of Delta flights arrived on time during the first half of 2026, the second-best performance of any major North American airline behind Alaska (via Travel+Leisure). Those figures become more impressive when you consider the sheer volume of flights Delta operates — 5,500 daily flights to over 300 destinations with over 200 million customers in 2025, according to the airline.

Of course, being generally good at everything isn't always enough when another airline wins the only category it competes in. Delta's average finishing position across the three JD Power cabin class segments is 1.67, an insanely strong showing that makes it the most consistently well-rated, full-service airline in the country. If you're looking beyond JD Power and combining passenger satisfaction with the statistical facts surrounding reliability, network scope, baggage handling, in-flight experience, and cost, it's easy to see why Delta is a passenger favorite.

Surprisingly, Southwest Airlines sneaks into first place with an asterisk above its name. But don't get confused — it still deserves its place on the podium. Southwest only competed in the basic economy category, but it won that with a total of 670 points out of 1,000, securing the top economy spot for an outstanding fifth consecutive year. That's not luck, that's an incredible customer experience infrastructure.

The result is even more notable considering just how much Southwest has changed. Many considered the airline's decision to abandon the open-seating model that defined it for decades as self-sabotaging. And when it introduced the sort of fees and restrictions it once used to distance itself from its rivals, loyalists were livid. JD Power specifically highlighted the significance of those changes, and noted that fees usually have a major impact on passenger's satisfaction and view of an airline. Yet, at least for now, customers still rate Southwest's economy experience more highly than anyone else's — despite the backlash for calling out the common habit of rushing to stand up when the plane lands.

Other stats back it up, too. TPG ranked Southwest third overall in 2026 and third for reliability, although it slipped much further down the rankings for experience and loyalty. Cirium (via Travel+Leisure) noted the airline's 73.79% on-time rate through the first half of 2026, which was also considerably weaker than Alaska or Delta. So, is Southwest genuinely the best airline in America? Probably not, if you're measuring every aspect of an airline. But under the rules of these rankings, it does exactly what matters most: It leaves its passengers happier with the economy experience than any other carrier. Considering that's where the overwhelming majority of travelers sit, that's not a meaningless victory.
