Overall it was fine, however one of my two checked bags did not arrive and I was told it was left in Palm Springs. I don't understand how one of the two bags made it through fine but the other got lost .

Overall it was fine, however one of my two checked bags did not arrive and I was told it was left in Palm Springs. I don't understand how one of the two bags made it through fine but the other got lost .

The seats are very small. I’m 5’ 3”, so don’t think I should notice. The food selection was non existent and very disappointing. 5 hour flight plus TSA, etc. I would have appreciated a small salad, crudités. Something fresher not just chips.

Was notified the departure would be late. Later on it was suddenly on time. Traffic by LAX was horrendous, and I missed the flight.

you sent me to some shitty "Airfaireassist" thing that did a bait and switch on the faire. Won't be using Kayak ever again

Every thing is on time, boarding, landing nice and smooth. But No tv? No food for 6 hours flight?

I don’t think Alaska coordinates with Kayak. I did not get a “check-in” email inviting me to check in 24 hours in advance. Had to wait 20+ minutes to get a wheel chair.

The plane was delayed which was annoying. No seat back screens is a bummer. Staff if great

First Class seats had no more legroom then Premium Economy. There was no working WiFi or entertainment. I would have rather paid $400 more and flown on United for the 6 hours from EWR to SFO.

Overall the flight was on-time and plane ride very comfortable. The free snacks not so good - only a small bag of pretzels and no milk. I wanted milk. There was not entertainment on the plane unless I wanted to download their APP. But I would consider flying with them again and be more prepared on my part with food and entertainment.

This was more with the third party booking through Kayak but my KTN for Pre-TSA, even though I entered it, wasn't assigned to my ticket when I got to the airport. I had to go through regular security. Also the Alaska app had trouble loading my ticket in the first place and I had to ask for it to be printed. Alaska Airlines was great but wanted you to know about this hiccup in the ticketing interface.

My 90 year old father flew with me. He needed wheel chair assistance and is nearly deaf. The staff was amazing with him.

It was fine. Nobody was outstandingly friendly but no one was rude and everything was smooth . The captain thanked us for flying but no one greeted me as I walked on the plane or as I exited which is the least they could do lol

Clean, friendly, roomy. But check-in from the phone link was terrible. Repeated attempts wouldn’t save at the final step. Just kept spinning! It was very frustrating. Finally, I used the app (vs website link) to check-in which worked very smoothly on the first attempt.

Check in on the web portal was cumbersome! After several attempts I finally got the boarding pass.

Excellent flight and even arrived 23 min early. No entertainment , or wi fi on board, but I downloaded a couple of movies beforehand which kept me entertained. Really like flying Allegiant airlines.

WE were delayed about an hour and never any communications from the employees working the gate. We also were moved to a total of three gates.

I love how they show love to their customers and care about them too.

I liked how when I got on board how fast we ended up taking off but what I truly disliked was how uncomfortable the seats were. There was truly never a time that I could ever get comfortable during both of my flights. The seats could get away during shorter flights but flights 3 hour plus makes it hard to enjoy.

The crew was great and the flight was very smooth. Can’t really judge food since I did not get any because it costs money. The seat was comfortable for what we bought. Thanks!

Crew was great. No entertainment and food and beverage was for purchase only, even water
