The plane was brand new and very clean and spacious. The flight was also so cheap. The negatives are that the seats don’t recline, there is no Wi-Fi on the plane or option to even purchase Wi-Fi, there was no entertainment, and because of the low prices, not even the water is complementary. Excellent value

Gate suddenly changed noted destination without an announcement. Turns out there was no gate change, just a mistake, but it was not handled well. The pilot announced we were in the incorrect city upon landing as well.

NOTHING.

Our flight was canceled two times by Spirit, and we had to stay another day due to the fact that the airline has limited availability for rescheduling canceled flights. Once the third flight arrived, there was an issue boarding due to a beligerant passenger and the flight was over an hour late. However, the entire time the issue was being resolved, Spirit told the passengers waiting to board NOTHING. Everytime a question was asked about whether or not we would be leaving, the staff was rude and avoided answering. I will never fly Spirit again, as they truly do not care about their customers.

enough space to move around

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

Nice flight. No issues. Flight staff was great.

Front desk check in guy in Orlando was a bit shady. Asked that we pay for our check-in bags with cash and wanted 10$ cash to put our seats together. I did not give him cash and had to ask for a reciept for the checked bags. We were 4 hours early for check in.

The crew was really nice.

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.

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......

Nothing - the flight from Chicago to Philadelphia was delayed by about 2 hours. Luckily, was able to get the flight switched to a Chicago - London direct flight.

The connecting flight from Philadelphia to Manchester would've been missed. So, American Airlines booked the same flight for 24 hours later. Luckily, they offered a different flight. Due to the flight changes, the prepaid ground transportation from Manchester to Leeds wasn't used. Transportation from London to Leeds had to be purchased at a much greater additional expense.

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!

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.

Despite plenty of empty seats, the ground personnel would not consider changing our seat assignment at the gate to allow us to sit together.

Decent boarding group, same snacks, same flight attendants (who were very nice)

My only gripe is that paying for an assigned seat is only allowed 48 hours before takeoff and costs at least $30, twice what Spirit charges to allow you to select a seat during booking, so it is worse. No one watched us to ensure that we didn’t use the overhead bins (a stipulation of the fare) but we did comply anyway. We chose to take our chances and were assigned seats at the gate 16 rows apart and both in the middle seat.

We were unfortunately stuck on the tarmac for 45 minutes. I ran to my connecting gate but they had already closed it. There wasn’t a service rep at the gate. I walked to another gate and there was a very helpful rep who rebooked me to a nearby city. It overall was disappointing and caused me to get home about 3 1/2 hours later.

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.

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.
