Pros: "The flight attendants were pretty nice and attentive. The captain was good at keeping the passengers updated."
Cons: "The 2 hour delay was not fun while we sat waiting on the airplane. I realize this is not the crew’s fault."
Cons: "The flight was cancelled and we were only notified once we reached the airport. I will never fly Frontier again."
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: "The crew was great. The flight was smooth and comfortable. I paid $25 extra for extra legroom and closer to the front... and an aisle seat. It was totally worth it."
Cons: "The flight was delayed 2 plus hours."
Pros: "The price was cheap"
Cons: "The seats were miniature, you dont get any food/snack included, it took 1 hour to get our baggage, it took 49 minutes to get off of the plane, the pilots were late on the flight there, the plane was delayed 1.5 hours on the way back, you have to not only pay for the flight but then you have to also pay for your seat. I will never fly frontier again."
Cons: "The flight was super delayed because Frontier was sharing a gate with another airline..."
Pros: "The staff was a well oiled machine! Very funny & accommodating. They were all very friendly & helpful to all of the passengers. Everything was clean & orderly."
Pros: "Nothing"
Cons: "The flight from St. Louis to Orlando was delayed therefore the flight from Orlando to San Juan was also delayed and I was not given a chance to go home. My only option was to receive a $20 meal voucher and wait in the airport another 24 hours. The staff was rude and there was no communication between one flight crew to the next. Worst experience ever and I'll make sure to tell all my friends and relatives never to use your airline."
Pros: "The crew was wonderful"
Cons: "In one weekend had two flights that were very delayed. Plus the return Orlando flight the cabin pressure was not regulated very well."
Pros: "Started with the nickel and diming during check in. The app wouldn't take my card so I had get on the website. Apparently buying the ticket doesn't give you a seat, you have to pay extra for that. Taking more than a laptop bag or purse, that's extra. Right there, your low fare is shot to h#ll. Definitely check the hidden costs before booking. Then came a 5 hour delay of the flight, apparently the plane had mechanical issues at it's previous stop. Frontier provided $10 meal vouchers, which doesn't go far in an airport. Seats don't recline at all and you feel like you're in a cattle car. The seat back tray is about 6" and doesn't hold much. The combination of turbulence and a pilot yanking the plane around during landing brought out the air sick bags by several passengers around me. Then on the ground, he was racing around and taking turns like an Indy500 race car. I seriously thought he was going to do a handbrake turn into the parking spot. Frontier provided vouchers worth $100 per ticket for the flight, but only good for another Frontier flight. I don't think so..."
Cons: "Several hidden costs. Uncomfortable seats Rough landing"
