I love Delta, especially their newer planes that have screens in the backs of headrests and free movies.

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.

the comped hotel

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.

The direct flight was really nice.

That entertainment had an extra cost.

Entertainment, and leg space.

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.

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,
