I like the fact that the airline had a very clean plane the flight was wonderful it wasn't a bumpy ride for the days that we flew didn't much like the layovers were too long took away from my time for my vacation so I didn't get the full benefit out of my vacation so I wish that they would offer a straight flight and I may consider Flying Alaska again

The flight from Atlanta to Seattle Washington the flight attendants were very nice except for when we switch planes and from Seattle to Honolulu the flight attendant was very rude that would play a factor if I fly with Alaska again but with that being said I don't think anything would be said to the flight attendants about their attitudes but it plays a big part in your Service

It is competitive with other major airlines in quality at a reasonable price.

I blame unprofessional attitudes of check in counter staff as the reason for our lost bag. Entertainment required a download on own device, but was not well communicated and on board option was expensive to rent. Food seemed great quality, but I would y know because I wasn't about to pay the outrageous price.

I am 6'6" 300 pounds ... So I regularly book first class for trips over 2 hours in length ... Delta remains my #1 choice for both value and overall experience in first class. The difference between Delta and all other domestic carriers is just overwhelming. United and American/US Air could learn a lot from Delta. I could have flown this trip direct on United, but chose to fly through Atlanta on Delta for less money and a better experience from the baggage check to the gate to the in-flight experience.

Why is there not saying precheck to use after you've been funneled through customs? ATL is advanced enough to have kiosk for arrival, even for those confused and not with global entry, but then forces you to wait in security line instead of the typically faster tea precheck line. Every minute I'm in line, I'm not spending money

Its a scam! They act like they are giving you a break by having you buy cheap flights but in reality it costs more than a bit more expensive flight. I had to pay $45.00 each bag no matter if it was checked or carry-on. In total round trip I paid $180.00 extra just for my husbands carry-on as well as mine. Must add that our flights together cost 286.00. We should of went with American Airlines. On top of that we couldn't select our own seat if so, we had to pay extra, so we had to sit separated from each other. It was ridiculous! Never Again with this company!!!!!

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.

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.
