Horrible leg room Never again

Matthew, Apr 2026

Zero issues with this flight. Crew was outstanding and flight was super. Plane was clean and fine. The seats need more padding and water should be provided without cost. I recognize it's Frontier but there are some things that should still be part of the flight. But still very satisfied with the experience and quality.

Crew was awesome!

2.0 Poor

Amelia, Mar 2026

The crew acted like they had never done this and kept barking passive aggressive orders at people. + the security line + the delay + sitting on the tarmac for 2 hours + none of the apps or signage updating with correct times

4.0 Mediocre

More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!
