Only real problem was flight times, Frontier "nickel-diming" you to death on everything from carry-on bags to charging for any snacks or drinks other than water. Guess that will come next. Seats are way too close together. In the event of an emergency, lots of people will die. Troop seats in the C-130 "Herky" were more comfortable. Yes. I was in the Air Force, served in 'Nam. Flying today just plain sucks, Greyhound bus with wings.
