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.

Did not have In flight service on my round trip due to turbulence. I did not partake in In flight entertainment. Flight descending into LAX was very turbulent. It would have been nice if the pilot communicated with us during that rough descent into LAX to ease the minds of some of us more nervous flyers.

Before I even boarded this old white man , a fat Samoan lady, and a short brown guy were at the desk. They asked if we could have 15 volunteers to get free checked bags cause it was a full flight. I waited in line, I got up to the short brown guy and he asked for my boarding pass and I showed him, he said that he can’t check my bag because I wasn’t given a seat yet. So he had me go to the next line with the old white guy, but before I switched lines I asked him, well if I go to that line, will I be able to check my bag so I waited in line and he said yeah, it doesn’t matter , I’m good. So I switch lines and wait in the line of the old white man, with every guest before me he was very sweet , making small talk, smiling and had great eye contact( all of the people he was talking to was white) I come up and he doesn’t look at me , then says I’ll be right with you, I wait for him to initiate and when he does he’s like what’s up? I was like the man next to you told me I needed to get checked in before I can check my bag. He’s like what’s your last name and I say Valenzuela , and he said we’re not there yet, all while not smiling, no eye contact like he was with the other guests. He said we’re will call you when I get to you. So I go sit down and I’m sitting down for less than a minute and he calls me and someone else. I go up and say Valenzuela and he’s like who are you and I’m like Valenzuela , he’s like hmm and says don’t go anywhere and calls someone else. I finally get my seat and I go back to the short brown man and ask if I can check my bag and he said there isn’t any room available and I was like? Wait you told me and then the fat Samoan lady said yeah we don’t need anymore bags thank you. I was dumbfounded and just walked away. So rude. Terrible experience and terrible communication on their end.

Our late returning flight was annoying. The plane was small, but it made boarding and disembarking quicker. I do wish they offered a gluten free snack.

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.

The flight was delayed, but once it arrived everything moved right along.

They canceled my flight with only a couple hours before checking in at the airport and offered no alternatives to get home.

The ticket I purchased through Kayak did not show up in my Alaska Airlines app, and neither of the codes given to me worked for online check in. I've never had to show up to the airport at 6am wondering if I've been scammed. Cheap flight fare or whatever does not play well with airlines and I will be wary of using Kayak in the future.

Everything about the flight was lovely. My only suggestion would be to offer a few more options of tv series from Apple TV or HBO.

After the door had been closed, the cockpit makes an announcement that catering is running late and it is not the airline's fault. It is their fault in the sense that we had to sit for 2 hours or more when we could have stayed in the terminal. Poor communications between catering and airline. This caused a young man to lose his temper and he went storming out hitting objects. He had complained to the gate agent that he had already waited at the gate 7 hours and when can the airplane leave? Airilnes do a poor job of explaining delays, maintenance issues, etc. whereas being truthful may gain more sympathy or understanding.

We were told the flight was delayed 5 times, then it was moved to the next day.

The experience with American Airlines was good, although the Philippines Airlines flight was much better (better seats, better food, better entertainment options, overall better). Again, the MIA to LAX flight was fine, but nothing in comparison to the comfort and accommodations of the Philippines Airlines flight from LAX to MNL.

Loved the crew . Absolutely no complaints. Except for luggage lost

Wish some foods provided rather than just biscuit/cookie for flight more than 2 hours

We are too tired and frustrated to comment politely at this point

After we landed we sat on the tarmac for 1.5 hours waiting to get to our gate. Ridiculous.

The flight crew was rude. We were in first class and no one even offered water until an hour after we were in the air. Horrible experience

American almost always Delays flights from Austin to Dallas and back. I cannot believe they have such poor service on this route. I was about to switch to American from Delta, but they gave me enough reasons not to.
