The boarding went quickly and was well organized

That the price to take a small carryon was just as expensive as taking a large suitcase, ended up having to pay and extra $80 r/t for a small bag and I just that's standard for them. There were no barf bags in any seats, believe me everyone around us was looking as the person next to me was getting sick on the landing because it was crazy rough. When we finally were able to get an attendant over she was as rude as could be, I'm sure this sick person next to me was sorry she "inconvenienced" the crew member, if they just put bags in the seats pockets like every other airline this wouldn't have been an issue. The seats were very uncomfortable with no padding and not able to tilt. The tray tables were nonfunctional, too small and did not extend to get anywhere close enough to reach you. The plane ride itself felt like we were on a old school bus on a gravel road. I had a round trip ticket with frontier and both trips were equally as bad. I will never travel with them again, Most of us weren't even sure if we were going to survive take off with out the plan breaking or something.

We had to go back to the gate after we started the taxi to take off because some idiot had remembered he left a lithium battery in his checked luggage... The service cart kept hitting me and the attendant didn’t even say sorry or excuse me... aisles are too narrow... seats are too small. The guy next to me wouldn’t put the arm rest down because he felt to cramped, so he was hitting me with his elbow all evening... I’m just not happy, but glad to be home.

I was asked to gate check my bag, which I did. Then waited an hour on the tarmac while they “rebalanced the baggage” which turned out to mean “taking 60 bags off the plane and leaving them.” They didn’t ask for volunteers or even tell us until we got to baggage claim and our bags didn’t show. The carryon I was asked to gate check will now be held at least 24 hours. Totally deceitful and unprofessional.

Overall I would say I was pretty impressed with Alaska, their crew and their service. I would say that the part I most enjoyed about your flight services was the gogo inflight internet. On my iPhone 6 it worked perfectly and i happily enjoyed multiple free movies on my flight. My wife did experience some troubles connecting with her LG 6. Hopefully as you go along you will continue to work to get better support for all phone types.

I think mostly it is because the world has become so allergy sensitive that these things must be avoided at all cost, but I'd say my least favorite part about the flight was the inflight "snack" service. I don't know where these biscotts came from, but I miss the old days of peanuts and pretzels. I will commend you that the drink cart came around 2 times during our flight. I think that is great. But the drink cart was definitely missing Dr. Pepper.

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.

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.
