Don’t fly with Alaska if you have a layover in Seattle. Guaranteed to screw you over. We waited at terminal S3 &were >2 hours delayed(mechanical issues)and told to change terminals to a different plane that required riding 3 shuttles to get to new terminal N14. Then they delayed the flight even further and changed gates again. when I went to the customer service in terminal N, the manager turned me away without apologizing & refused to assist me but mandated I leave her alone as her shift is nearly finished and insisted I totake another 2 shuttles to terminal C so I can just talk to another service rep while dragging my family of 4/ kids in tow.

Everything was good. Please have a wheat free option for snacks in the future.

Not delay for a few passengers. That was uncalled for. If idiots can't make the flight on time thats their fault. Why should I be punished for them? No more holding the plane for one or two people

How can I review what was denied to me. Instead of offering to let me pay for the ticket I got booted of my flight with no way home and no choice but to purchase another ticket for 12 hours later. Filing a complaint with the DOT

I like them since I live in Alaska and I don't have much choice

Flight was delayed about 40 minutes by a mechanical problem. This made a long day even longer. Otherwise good.

After we boarded there was quite a long time before we actually took off, and there were no announcements from crew about why we were delayed. Later when they did make announcements they were largely inaudible. There was no food (other than for purchase) on the flight and no entertainment. Thats not a complaint, just explaining my ratings in those categories. The flight was smooth. Baggage claim was rapid.

We were flying 1st class for a special occasion. This was a Hawaiian airlines flight. It was exceptional. Very comfortable seats and space. Extremely attentive crew. Food was great for airline food. They provided tablets to watch and full headphones to listen. This was the best airline experience I have had in decades.

you could have gotten me there on the day I was supposed to be there, not a day later. Paid for 3 nights at a VRBO and got to spend only 2 nights there.

I requested wheelchair assistance in Seattle transferring gates and in Anchorage to get to baggage claim. No assistance was provided at all.

dropped my bags at Seattle Delta curbside. 1.5 hours before departure. one bag oversized made it. the other was left at curb and mishandled. poor communication from delta in sjc baggage claim. No internet on flight and food choices in business are horrible. You are forcing us to fly Alaska which is shockingly better than the Delta experience. that is a low bar.

Delta is the best. It was all very easy and on time.

Delay from Atlanta to Tampa was simply unacceptable. Multiple delays led to us landing after 3am. Worst travel experience of my life

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

The flight was done by SkyWest only WIFI no entertainment center are available on the CRJ

My flight was delayed by 4 hours in 30 minute increments. The gate agents were amazing but the communication was not. We were told that there was a maintenance issue but they didn't know what it was. That didn't inspire confidence. Then they said they found it and it was fixed and the pilot just needed to sign off. Then the pilot needed to talk to the other pilot from the arriving flight and we'd be fine. Then we were waiting for the pilot to call back. Then the maintenance issue wasn't fixed. Then they decided we were getting a new plane (why didn't they decide this earlier??). Fine. But then they announced we were changing gates AND terminals. And we were boarding in 20 minutes. So we all had to run to the new terminal gate. We could have taken off at that time, but we then had to wait for all the people who rebooked on a different flight to book this flight again. That took 30+ minutes because there was only one gate agent. When everyone ditched this flight, I saw it as an opportunity to upgrade to comfort. Delta, the greedy jerks they are, charged me $121. After their delay, their fault, their issues, couldn't even discount an upgrade. They only handed out $12 meal vouchers for the delay. I can't even get a snack from starbucks for that.

Love me some Delta. One of the few airlines to recognize and support veterans. Easy boarding, flight was on time and arrived early and the flight attendants were excellent on this flight.

We sat on the runway for over an hour before departure. That was unwelcome.

Crew was nice, meal was good. Entertainment had to be rebooted 3 times and still did not work. Turns out there was residue on screen, it needed to be cleaned to prevent the touchscreen buttons from continuously activating. I had entertainment for the last 45 minutes of a 5 hour 45 minute flight. Really unacceptable for first class. Flight attendent indicated your cleaning solution creates this problem. Seems as if this is widely known, you should be using a different product or cleaning better. Really really disappointing which simply added to the wi fi on your planes with reliably never ever works.

Snacks and included beverages were appreciated. Boarding went smoothly. Plenty of overhead bin space. Seats get very uncomfortable after a couple of hours. After waiting 10 painful minutes for my walker, a very nice Delta guest agent pushed me in a wheelchair to the gate. It was finally delivered to me after another 15 minutes . Our checked bag was on the carousel long b4 I was able to retrieve it. Fortunately it was still there but somewhere along the way the straps we used to secure it were removed and and were not reattached. Wish I had made note of the agents name.

No flight delays. No need to rebook to make connections. Enjoyed second leg of flight on Iberia.

Wheelchair folks are great. Food not to my liking. Crew more interested in their lives than the passengers. Got the job done but just the minimum.

Flight attendants and crew were great! This plane was fine. It was clean and everything worked properly. Now, the gate change was not communicated. No text or information. It wasn't far with the gate change but it still changed without any communication. Not sure if this is on American or Kayakl. Also, internet was the worst. I would never have ATT. 3+hr flight and weak internet. I think I watched the commercials to get on at least 6 times. Terrible internet!

So excited very proud first of all I wanna thank kayak all updates very professional and fast alart And amazing cabin crew so nice to me they deserve big salute

Great flight - friendly and attentive team! Seats in coach were comfy, but a little cramped - but that is the case with all airlines ;)

Dreadful experience. Our flight was delayed more than 8 hours due to a maintenance issue and the assistance from rebooking was poor. I was travelling with a bad knee and needed assistance waited in one place more than 3 hours before someone came with a wheelchair. The woman next to me was a 91 year old great grandmother who had waited more than 4 hours. There were moments of support from the staff but it appeared as they were going against the direction of management. It was apathy, lack of ownership and dismissive responses with small moments of kindness and understanding typically from grey haired, female, veteran staff..

Everything was great except it became so hot on the plane I couldn’t sleep on my red eye flight. It didn’t really cool down till we started descending.

The only thing is if Wi-Fi is available after you land and taxi to the gate. It takes forever to get to the gate, and having the Wi-Fi continue would be great to bide the time at least 5 minutes before you arrive at the entrance. That is my only comment; otherwise, everything was good.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

Experience was fine. Seats were cramped, and we had to wait for repairs before we could take of. Even though the door remained open, we were warned that leaving the plane could cause difficulty trying to fly out later. Staff was pleasant, and climate control was fortunately working. We had trouble at the DFW terminal, but I don't think that was AA's fault.
