There was no wifi, there was no usb charger on the planes Frontier lowered the weight limit on suitcases from 50 to 40 pounds Frontier now charges for a seat...really? If i don't pay for a basic seat, do i stand the whole flight? Frontier now charges for the carry on, just like for the checked suitcase The bundle pricing is way over priced.

I am HIGHLY unhappy with the amount of money I spent on the flight. Paid in advance only to find the flight at a discount price a week or so before the flight. I will not fly frontier again and have bad mouthed your business since to anyone I have spoken with about flying (which has been many a people). Crew was mediocre and instead of moving me to a spot where I could gain some leg room they sat their flight attendant there. Won’t be flying frontier in the future.

They changed my flight and did not want to accommodate me or try to help me in any way. They do not care about their customers.

The flight was delayed and I had to cancel because I would have missed my connection and there were no other flights for the next two days. They also lost my bag!!

My first time to fly Frontier and loved it! Boarding was super easy as we only had personal items. Crew was helpful and funny and the plane was clean. Pilot was also great at landing the plane smoothly.

Poor communication. Plane was available, but crew to fly. It was not so flight was delayed. Our flight was overbooked, so carry-on. Baggage was denied without proper notification before hand. Cost of bags to be checked is outrageous.

Horrible flight, rude crew, someone had so mu h perfume on breathing was difficult.

Be prepared for crowds and chaos upon arrival at the Orlando airport

late late late late no accountability no refund no adjustment no reasonable solution

This isna terribly run airlines. If you're one minute late, they will deny your ticket. Don't waste your time or money
