I dislike that once I got to the airport in Cleveland before boarding schools go to Orlando they charge me $45 for a suitcase that if I would have painted with my ticket it would have been $25 and that's what it told me I had to pay at the airport if I wasn't going to pay it with my ticket it was only $25 not $45 so they charge me $45 and then when I went to board the plane to go in they tried to charge me $45 for a backpack that fits under the seat and wasn't a carry on then they charge like $3 for a can of soda I don't think I'll ever recommend Frontier to anyone or I would never travel again with them that is ridiculous being a disabled person and being taken advantage of is unacceptable

So many delays. My flight was eventually cancelled on Friday and was rescheduled for Saturday. The Saturday flight was delayed. All in all, i wasted a vacation day on Friday, I paid for a hotel in Denver for Friday night that I was not able to get refunded, I missed out on a day in Denver. It was a huge bummer.

Flight was cancelled on our way back home from Gudalajara, was speaking to a representative for almost 2 hours to get me on the next flight the flight representative forgot to put me on hold and told everyone how rude i was, i was not rude i was just trying to get home. The representative couldn’t help me so i asked to be transferred to a manager, after 2 hours i was transferred and the manager hung the phone up. Long story short i called back spoke to another manager Yana and she was the rudest lady ever! She basically told me for waiting to long i will have to be placed on a flight 2 days after my cancellation flight. I started to cry because i needed to be home and she basically did not care so i took the date. Never again and i will warn everyone about this airline and their customer service!

I found the reason for being late to be questionable They said heavy snow but as i flew in i looked out the window and saw all roads nicely cleared That does not happen in 3 hours

They did not get my liggage to the connecting flight And here i am in Ukraine with no winter clothes at 7 below 3 days later

Full plane, long wait to use lavatory. Crew was good, but should have upped their game under the circumstances, especially with regards to keeping the lavatory clean. The noodles for breakfast turned out to be porridge, and went straight to the waste basket.

if you have a hard engagement that you have to make, i hate to say it, but use a bigger airline. These guys are not dependable nyc -> miami. Have had 2 flights cancelled and delayed over 6 hours in the last 6 months. Only one scheduled flight everyday. If you can risk it, fine, but otherwise not worth it.

Service was awful. Delayed for more than 8hrs without an explanation of what type of maintenance issues were happening. Never given a straight answer as to what was happening. Food vouchers were only offered after the airport restaurants had closed. Once the plane was finished the crew had timed out and we could not leave till the following afternoon. Ended up being put up in a hotel for the night and lost an entire day of our weekend get away. Poor contingency planning on frontiers part. There was no reason

The dirt cheap, I can't believe an airline can operate at this low an airfare and still turn a profit-ticket prices

The hidden checked-baggage fees that were almost half the cost of the actual ticket for one bag. The non reclining seats. The lack of legroom. The feeling of cattle being herded into a slaughterhouse. The lack of friendliness with the RDU and MCO gate/ticket counter agents. The cost of having to pay $12 to ensure I sit beside my 5 year old son on the flight. Besides a free seat belt, having to pay for everything else under the sun. Surprised AC was free. Not even an in-flight magazine or barf bag. Which is exactly what I feel like doing after giving you my money......

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
