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.

Delta staff taking care of rude/beligerant guests first vedore guests patiently/kindly waiting in line ... children watched that behavior and the jerks recieved special treatment. Flight staff ripped up guests boarding pass in face. Staff allowed ys to board plane and put our bags under plane and then crew timed out before take off. Never will use Delta again.

Our original flight was delayed and Marika, at the Delta gate of another flight to the same city, was able to get us on the flight that was going to our city. We were so grateful to get home before the winter storm! We appreciate your staff and the help their quick, efficient manner to get us on a new flight!

Flight was on time-ish, no trouble really. Call center folks were great.

Our original flight was cancelled with no explanation. My girlfriend was notified of this and I was not. When I called to get my flight details I was informed that I was to fly out on a completely different day instead. After explaining that there was no chance of that happening, the call center rep was happy to help. The flight was now an American Airlines flight booked through Alaska. About 3 days before our flight we both received calls from American saying that they did not have our passenger information. Apparently Alaska just didn't transfer that over. We also now had two confirmation codes as the returning and connecting flights were still with Alaska. Once we got to the airport on the day of I was able to print my American Airlines boarding pass, however I could not print my Alaska boarding pass on neither American nor Alaska's kiosks. It was a redeye flight as well so there was no staff at the check in counters yet. We ultimately did get to our destination, but it was such a completely unnecessary headache to get there.

I had only 40 minutes to get to my connecting flight. Then the plane was 15 minutes late. They wouldn't switch me to a seat that was open closer to front of plane and my bag was lost w important things in it that I need for this evenings show. I'm a full time musician.

Improper handling of situation. There was flight scheduled later, but CS agent kept jerking us around. By the time I reached the United counter, the next flight was full. My total flight time was 36 hours. I still can’t believe that the pilot was missing. Worse yet, the agent at the gate could have made things much easier instead of telling everyone that a pilot was on his way to the airport.

Very friendly cabin crew made this trip pleasant and entertaining.

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

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,
