NOTHING !! I lost my flight because in the email I received you all put the wrong airline on it and nobody took responsability for it . I ended up paying $311.00 to get the next flight back to Austin .

In the email it was stated that my first flight was with British Airways, so i wasted time making the wrong line . Only to get to the counter and waste more tome trying to find me in the system to then tell me my flight is with American Airline . I double check my email where it clearly shows: 1st flight-British Airway and 2nd flight-American Airline . This is not acceptable, nobody wants to take responsability for sending me the wrong information in the email. Had I know both of my flights were with American Airline I wouldn’t lost my plane because I would make the right line to begin with .

No free food or drinks. Too many extra fees like for bags and seat selections.

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......

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.

Frontier cancelled the flight. Their alerts to my email came well after I arrived at the airport. The single check in attendant didn't offer an explanation and curtly told me next flight wasn't until 3 days later. Plus, you can never reach a person at customer service they won't guarantee a refund since I bought a discounted flight.

I really did not feel any more crowded or uncomfortable than any other airplane Ive been on. I sort of like that the tray tables are the size of a large cell phone- less bulky than regular tray tables.

The crew wasn't bad, just seemed unhappy to be there. There was some confusion with which gate we should be at, changed us three times before settling on the original gate. Boarding was no problem but then we waited without taking off for over 45 minutes. The pilot came over the intercom and informed us that he had no idea why we were delayed to take off, but that he would "find shortcuts" to get us there on time. The biggest gripe that we have is once we landed and went to baggage, several of us waited for golf clubs for close to an hour before a worker realized "they forgot" to turn on the button to allow oversized items to come out. Then she said "sorry I was busy with ticketing and Frontier doesn't have a baggage attendant". I just dont think the extra savings was quite worth the frustration.

The flight was so short we did not even get a snack, only an offer of a bottle of water; this was simply due to to short length of the flight. Basic economy had my wife and I 16 rows apart each in a middle seat. I was in the very last seat on the plane. Flight attendants were attentive and surprisingly very nice, legroom is non-existent (same as every flight in plain coach).

High cost to prebook seats was twice what Spirit or Frontier would charge

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.

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.
