They even charge for in flight snacks. Not a meal...the peanuts and soda you usually get free elsewhere. The flight attendant was rude to me. No wifi available for purchase that I could tell. Then at the end of the flight they had a big commercial-like announcement to push their credit card. It was very tacky.

Stewardess berated a man for leaving his backpack on the floor in front of him rather than politely addressing the issue. She told him you know better than that and don’t ever do that again. It was totally uncalled for.

Got to the airport at 4am for a flight that was supposed to leave at 6am. The flight finally departed at 11:40am. I missed my non-refundable connecting flight and had to book a new flight. All in all I probably lost $300 because of this situation. On top of that it was my birthday.

The flight itself was fine.

All the choices to eat were laden with gluten, salt, and sugar. Surely a salad is no heavier than what they carry, but might not last as long. For those of us gluten-sensitive, watching our glucose levels, or salt intake there’s nothing. A 40 minute gate change from B29 to A11 in PHX was barely long enough to walk far less find and buy a healthy meal. Yet again I arose at 4am and had nothing to eat until after 4pm. ALL the airlines can do better.

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.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
