The fact that my original seats were not given. The other issue was that Alaska wasn’t my airline but American was. They didn’t even tell me until I got to the gate, moved over to another and then got transferred over to my gate.

On the MSP to ATL leg the gate crew made a huge deal about checking rolling bags. They even stopped us at check-in and nearly begged us to check our bags pointing to the backed up jetway. But we had a lot of unpacking to do before checking our bags so we politely declined three times. On getting to our seats there were at least 8 open slots for bags near us. I heard a crew member call forward to say "tell them no more rollaboards" so they forced everyone left to check. On departure they slammed shut several very large empty overheads. WTF

The crew could not have been better. I was really pleased with the movie selection. However, the food is really terrible. I got a dish that was chicken, mashed potatoes and green beans, which would have been acceptable had it not been covered in bbq sauce.

Boarding was simple and efficient Seat was better than usual

Dinner was okay, the mid-flight snack was awful and made my wife sick, breakfast was better. Entertainment console crashed four times, first crew member didn’t seem to care (aloof for most of the flight), other attendants seemed marginally more interested. No one checked back to see if the problem was resolved. Flight attendants seem to be in “check the box” mode doing only what was necessary.

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.
