Plane was clean and modern and spacious, usb ports all worked. No TVs

Baggage pickup in Seattle took over an hour. We were told one, then moved to another, and then back to the original. What should have taken 15 minutes took over an hour. When waiting to board our flight in Seattle to return to DC, we were sent to 4 different gates before finding the right gate. I have walked every inch of Sea-Tac Airport. The actual flights were great. The rest, not so good. "Ain't no way to run a railroad."

Multi gate changes and flight delay were irritating. Food on board was terrible and expensive for what was offered.

Overall the experience was good. Check in at the bag drop was challenging as the system was having issues and there was only one attendant helping the passengers. My personal experience was okay as it was straight forward but there were many who were having issues. The flight was good. I did not use the in flight entertainment very much as I had brought my own but it seemed to work well.

Technically this was the flight where they lost my bags, but I already explained that on the review for my connecting flight, so I'm not gonna do it again.

Flight was delayed hour and a half. Gate was changed 3 times. After boarding, sat in airplane for another hour while mechanic checked windshield. Total of 2 1/2 hrs behind schedule. Very tiring since I had ben up since 4 am to complete the flight from Honolulu to Milwaukee.

Food was just ok..had snack box :( Crew was very nice

Boarding took longer, to shuttle to plane. Crew/pilot were great.

I was a little hesitant at first because I never flew on Alaska Airlines before. However at the time of me booking; this airline was one of few that were affordable & had a much needed direct flight option. I was more relieved when I got to the airport & saw that my local relatives chose the same flights. Also, on the flight to Seattle I chatted with a gentleman who flies more frequently than I do & gave Alaska Airlines a higher rating over competing airlines.

The Alaska employees in Milwaukee and MKE to SEA were top notch, very nice and polite. Seattle and SEA to MKE, not so much. I spent a lot to upgrade to 1st, and other than a little more seat width, it was a waste of money. Both legs of the flight, the seat bottom cushion sloped forward and I kept sliding out of my seat with every little bump, so I got no rest at all. MKE to SEA, the food was awful. If I had known that I was going to get a bowl of sawdust and dried rotten fruit for a meal. I would have stayed coach and saved a bundle of money. The cabin crew was excellent however. Alaska needs to enforce the rule that the seats at the gate stay open for passengers. I can't blame Alaska for the rude treatment of TSA swine, but they can make sure a hundred people get seats to wait an hour for their flights because a hundred jerks need to take every available seat for their bags and water bottles. The food from SEA to MKE was much better, but the cabin crew was not very pleasant. To top it all off, I found out that the woman seated next to me paid a lot less for the upgrade than I did. After arriving at MKE, everyone waited at least forty five minutes for our bags to arrive in a completely empty airport. So much for the promise of twenty minutes to get bags. In summary, the upgrade to first class wasn't worth the high price on Alaska. When I pay that much, I expect better service and treatment.

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.

The cabin temperature was nice and cool. The wifi was not working.

Could not get my connecting flight boarding pass until four hrs before departure! Ver annoying especially since the staff could not explain why!

First flight out and was 85 minutes delayed. Notification came out way too late

Flight be on time would be a good start. Then train your flight attendants to be attentive and friendly. This time they completely forgot my row for the measly snack! United, do better!

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

They had three choices for snacks - but you could only have one - and they ran out of the dark chocolate before they made it all the way down the aisle... Packed flight - limited service.

They opened my checked bag and even though my lock was tsa approved, they loose my lock and left my bag just like that. Incompetent people, very upset about it. I’ll try to avoid traveling with united

We fly to Ecuador frequently. Checking in is usually a hassle because most United agents take some time before they can verify that my passport doesn't require a visa to Ecuador. This time the process was even longer due to the cyber attack. But she was really nice to us. So glad we brought plenty of snacks to supplement the 3 flights from SEA to GYE.

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

The wi-fi was awful. I paid $8 each way and got little , except frustration. .

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!

Never ontime and always delays. Long waits for customer service and often app doesn’t work

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 ;)

American airlines suck they delay the flights all the time made me sleep in an airport because my flight was delayed and I miss my connecting flight

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.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.
