I Flew 10 Budget Airlines This Year and These Are the 3 I Will Never Book Again

Budget airlines kept expanding across the U.S. in 2026 as carriers pushed low base fares and more add-on fees. After flying 10 budget airlines this year, the three I would not book again are Frontier Airlines, Spirit Airlines, and Ryanair based on repeated issues across specific trips.

Frontier Airlines had the lowest fare, but the final cost climbed fast

Frontier Airlines ended up on my no-book-again list after 3 flights in 2026, including routes from Denver to Phoenix and Atlanta to Orlando. On each booking, the advertised fare was the lowest at checkout, but the total rose after seat selection, carry-on charges, and other extras listed during booking on Frontier’s website.

The most frustrating trip was a June 2026 flight from Denver International Airport where a standard carry-on fee added more than the base fare. Frontier states on its booking pages that bag prices vary by route and timing, and that was accurate in my case, but the final price gap made the original fare feel much less useful for comparison.

What is confirmed is the airline delivered the seat I paid for and the flights operated. What was not great was the overall value once the fees were included, especially compared with Southwest, which still includes 2 checked bags in its base fare policy as published by the airline.

Spirit Airlines was better organized, but the seat and delay issues added up

Spirit Airlines made my list after 2 flights in 2026, including a trip from Fort Lauderdale to Newark. Spirit has long marketed itself around ultra-low base fares, and the airline confirmed in its published fare structure that bags, seat assignments, and many onboard options cost extra.

The bigger problem on my trips was comfort and timing. On a spring 2026 flight, the boarding process moved quickly, but the seat pitch felt noticeably tight over a flight of more than 2 hours, and a delay at the gate stretched the total travel day well beyond the scheduled arrival time listed on my boarding pass.

Spirit did exactly what its model promises on price. Still, if the difference between Spirit and another airline is small, the tradeoff may not be worth it. That matters in large U.S. markets like Florida and New Jersey, where travelers often have multiple nonstop choices on the same route.

Ryanair was cheap in Europe, but the rules were the hardest to live with

Ryanair was the only non-U.S. airline on my list, and it made the cut after 2 flights in Europe during 2026, including a route tied to a U.S. vacation itinerary. Ryanair clearly states its baggage and check-in rules before departure, and the airline has built its business around strict enforcement of those policies.

The issue was not hidden terms. It was how little flexibility there was when plans changed. On one flight, the personal item size check at the airport was more aggressive than what I experienced on JetBlue, Breeze, or Allegiant in 2026, and that meant extra time, more stress, and another fee before boarding.

For travelers starting in the U.S., that context matters because many budget-minded international trips combine a transatlantic ticket with a separate Ryanair segment. Based on 10 budget airlines this year, these 3 stood out for the weakest mix of price, comfort, and convenience, even though each one delivered the low base fare it advertised.
