Due to plane delays on both legs of my flight home, I had to be rerouted from Santa Rosa to Las Vegas on Skywest and then to DCA on American. SkyWest airlines sat on runway in Las Vegas for 20 minutes waiting for gate to clear. My boarding pass for American that I was given by Alaska was incomplete and the Las Vegas airport lacked signage and departure boards. I barely made my flight bc it was so confusing. American Airlines has a much better wireless connection. I’ll never fly Alaska again. It clearly has problems.

We left about 30 minutes late due to ramp issues. It did not impact me, but I know others on the flight had very tight connections to Maui.

The crew was very friendly. Boarding was quick and efficient.

No WiFi. Terrible food. Very long walk to the gate and from the gate after landing. Gate changed without notice.

I enjoyed the Starlink access but didn't have much time to use it. It also kept dropping me so I gave up. The food was very good though when I asked for a different "dessert" they didn't have anything. Chocolate Brownie Cookies are not suitable for everyone...maybe children. The flight staff were amazing - at least in First Class! My first time ever! The trip from Boise to San Diego was FAR better than going to Boise.

One of the flight attendants treated my grandma who is 77 years old badly and would respond sarcastically. Example my grandma "do you have and honey by any chance" the flight attendant "does this look like a restaurant to you. She was also very rude to myself and my children giving us attitude and being sarcastic when answering.

we waited for 50 minutes to check a bag and missed a flight. do better.

The flight crew was very professional and pleasant. Our flight was delayed 3 hours, but Kayak informed me in advance

I really hate the seat assignment at the gate. I understand it is so families can sit together but it caused me and others a lot of unnecessary stress and confusion, enough for me to not fly Alaska again. The app is so awful that it did not even update my seat assignment on the boarding pass but sent me a notification of my seat... it showed in Apple Wallet but not in the Alaska app itself. That only made the stress worse. I think most people like myself prefer to know where they are seated at check in 24 hours before so they don't have to anxiously hang out at the gate the entire time. This is not a good use of your agents time either to be dealing with all of us asking where we are sitting. You should automatically assign the multiple seat purchases to be together before they check in and fill us solo travelers in those gaps as we check in.

Alaska Airlines have beautiful new airplanes that have comfortable seats but tight for a tall person like myself. They do provide upgrades to flyers but at a $140 cost. My flight went smooth and prompt as well as without a hitch. The flight crew were warm and friendly as well as very attentive. I'd recommend this airline over Frontier airlines any day.

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
