Pros: "It was good"
Cons: "All those extra fees even for a drink!!! First time on frontier not sure if I would use it again"
Pros: "Incredibly uncomfortable seats. Packed like sardines with no opportunities to move."
Cons: "Make the seats more comfortable with more leg room"
Cons: "My flight was extremely delayed for no apparent reason and it made me waste half a day sitting in the airport"
Pros: "Giant fat guy sitting in the middle seat next to me!"
Cons: "Not being delayed?"
Cons: "Seats were made of hard plastic and did not recline. No radio or TV. No free food offered. Waited hours as they had to locate a mechanic, repair an armrest and then do the paperwork to prove that he had finishes the armrest!"
Pros: "Crew was great. Fast flight. Lots of information from the pilot"
Pros: "Crew always professional and friendly, nice plane, clean, love the low price no frills fare. Hint; you do not have to pick your seat unless you really have a reason to sit next someone or need Moor room. Just click on no thank you. Why pay extra."
Cons: "Seats are not that comfortable, I now bring my own cushion. I suspect that people are not being checked to make sure that they paid for a carry on. If it's a personal item it should not go overhead. De plane process is slow because of the passengers fumbling over head."
