I flew Frontier about 5 years ago, when they served hot snacks on thier flights. I went from PHX-DEN-PHL. The DEN-PHL was a great flight, hot snacks served, with the run and coke I ordered and the Direct TV, the 3 hours flight went by very fast, it was one of the best domestic flights I had been on. Too bad they stop the free snacks.. Great report.
