10.0 Wonderful
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!
A
2.0 Poor
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
C
4.0 Mediocre
More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!
