Picture this: you’re crammed into a seat that feels like a torture device, your flight’s delayed for hours, and your bag vanishes into thin air. That’s the story too many Americans shared in 2025, with airline complaints spiking nearly 9 percent from the year before. Recent Wall Street Journal rankings and DOT reports paint a grim picture of carriers drowning in passenger fury.[1][2]
Here’s the thing, folks. Low satisfaction scores and sky-high complaint rates have folks vowing “never again” on social media and review sites. Let’s unpack the top 10 offenders based on hard data from complaints per passenger and operational flops. Buckle up, but maybe not with these guys.
1. Frontier Airlines
Frontier Airlines snagged the unwanted crown for highest complaint ratio at 23.3 per 100,000 passengers in 2024 data analyzed in 2025.[2] Tied for dead last in the WSJ’s 2025 scorecard, it bombed in four out of seven key metrics like delays and bumping. Passengers rant about nickel-and-diming fees that turn cheap fares into expensive headaches.
Even with 671 complaints in one recent DOT month alone, Frontier keeps cutting corners on service.[3] I get the ultra-low-cost appeal, but when bags go missing and flights sit on tarmacs forever, it’s no wonder Americans cross them off their list. Honestly, it’s like playing airline roulette with your vacation.
2. American Airlines
American Airlines tied Frontier for rock bottom in WSJ rankings, boasting the worst cancellation rate at 2.2 percent.[1] It led DOT’s complaint pileup with 1,574 submissions in May 2025 data, dwarfing rivals. Weather and staffing woes piled on, leaving travelers stranded and seething.
Never higher than sixth in any category, American’s network complexity just amplifies the chaos. Folks swear off after endless delays and poor communication. Let’s be real, when your big legacy carrier can’t keep it together, trust evaporates fast.
3. Spirit Airlines
Spirit clocked a hefty 12.8 complaints per 100,000 passengers, second only to Frontier.[2] Though it improved on-time performance in WSJ metrics, persistent gripes about service kept it mid-pack at fifth. Budget tricks like fees for everything from seats to water fuel the backlash.
DOT tallied 333 complaints in a single month, signaling no end to the misery.[3] Passengers feel treated like cargo, not customers. It’s hard to imagine booking again after one bad ride turns into a horror story.
4. JetBlue Airways
JetBlue’s 10.4 complaint rate per 100,000 put it third worst among majors.[2] Landing seventh in WSJ overall, it fought back from prior slumps but still trails on reliability. External hits like hurricanes and recalls didn’t help the vibe.
With 251 DOT complaints logged recently, baggage and delays remain sore spots.[3] Once a darling for legroom, now it’s just another option Americans dodge. The shine’s worn off, leaving folks skeptical.
5. United Airlines
United earned the dubious honor of worst baggage handling at 7.07 mishaps per 1,000 bags.[1] Sixth in WSJ rankings, it racked up 832 DOT complaints in one month. Solid on cancellations but dragged by lost luggage nightmares.
Sixth-place finish masks deeper issues like tarmac woes. Travelers vent about feeling invisible amid the giant operation. No surprise many pledge to skip United next time.
6. Allegiant Air
Allegiant shone on cancellations at 0.55 percent but tanked on extreme delays in WSJ data.[1] Its deliberate hold strategy frustrates passengers waiting hours. Disability complaints hit 14 in recent DOT figures, above average.
Second overall in rankings hides the point-to-point pitfalls. Leisure flyers get burned by mechanical snags often. It’s a gamble too risky for repeat business.
7. Delta Air Lines
Delta slipped to third in WSJ after a CrowdStrike outage spiked complaints and cancellations.[4] Third-highest DOT submissions at 684 show the fallout lingers. Tarmac delays worsened too.
Still tops on-time arrivals, but trust took a hit costing $500 million. Loyalists waver after mass chaos. Even giants stumble hard.
8. Hawaiian Airlines
Hawaiian saw complaints jump in DOT data, with 75 submissions recently.[3] Low rate at 3.8 per 100,000 but integration with Alaska stirs uncertainty.[2] Island hops turn sour with delays.
Exotic appeal fades amid service slips. Passengers dream of paradise but wake to frustration. Regional focus amplifies issues.
9. Southwest Airlines
Southwest topped WSJ but drew 197 DOT complaints, down slightly.[3] Best low complaints overall at 1.5 per 100,000, yet volume adds up.[2] Baggage pros, but delays irk.
First win since 2020 feels shaky with changes. No-fee fans forgive less now. Even kings face revolt.
10. Alaska Airlines
Alaska ranked fourth in WSJ, middling on baggage and complaints.[1] Low rate at 2.6 per 100,000 holds steady.[2] Hawaiian merger tests limits.
Reliable West Coast pick, but national gripes grow. Fewest bumps, yet not immune. Growth pains hit hard.
What This Means for Your Next Trip
Complaints hit record highs in 2025, with rates far above averages signaling deep discontent.[2] Check DOT stats and recent rankings before booking to dodge the drama. Your peace of mind’s worth it.
