Crew was great. Helpful, friendly, sense of humor. 👍🏽 Seat was really uncomfortable -- too concave ( why make them like that???) but worst, This is the first flight I've ever been on in my life where the seat did not have the option to recline!!! Whaaaat??? I was so sleepy but never was able to get comfortable enough to actually sleep. I forget which model of a plane it was exactly, but it was a 737 of some type.

Whaaaat??? I was so sleepy but never was able to get comfortable enough to actually sleep. I forget which model of a plane it was exactly, but it was a 737 of some type.

We had tried to change our seats in the app multiple times before check-in but the flight was seemingly full. When we boarded, there were several empty seats available that my husband and I were offered to take by one crew member only to be told by two others that those rows were reserved for the crew members’ bags.

the departure time was changed several times. At the end we were late 2 hours and 15 min. It was a poor experience

Smooth boarding, smooth flight. Crew was good. I can't believe 5 hours went by so quickly!

Well, the flight hasn’t taken off yet… it will be 2 hours late by the time the t does…

I had never flown Alaska before. Years ago I flew constantly. Flying these days is not a glamorous experience. It’s not that easy to get inexpensive direct flights either. Not glamorous but reasonably priced and comfortable. I appreciated the inflight WiFi (for messaging only but that’s ok, I like to read on flights). I didn’t check the inflight entertainment, see above. I was lucky on the AUS => SFO flight—they needed volunteers to check bags at the gate. That bumped me up a level in status so they let me move to an empty exit row. The return flight I was assigned a seat in one. Very nice. As pleasant a trip as possible these days.

Ground crew at SFO checking didn’t print my boarding passes for my second leg … creating a full mess at LAX So the desk asked for my passports, and was able to check in my luggage up to the final stop, they never realized that our journey was made up 2 legs.

no entertainment which was ok with us. Great crew, great ascent, rockier landing, empty air lane so very comfortable. fun pilot

I feel that for the price that I paid, I should’ve received zone one boarding. Said I was zone two. And even though I paid for an upgraded seat, I was lucky to get a space for my carry-on baggage. So I think the value wasn’t there.

I did not find out about the delay until I got to the airport where I had to wait 3 hours, not cool. I missed a special gathering. Everyone on staff was very nice.

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

New boarding doesn't make sense. Filling front first is slow.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

My seat was changed at the last minute and I was moved to the last row, right next to the bathroom despite selecting my seat well in advance. I was also made to check my carry on due to space but when I got on the plane there was significant empty overhead space. Picking up my carry on from the luggage carousel added time to my trip which had already been extended due to delay.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

There was a loud squeaky sound the whole time we were flying.

I didn’t not like that I could not select my seat and ended up with the worse seat.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

Excellent staff helping my 96 year old senior promptly with her oxygen needs

Flight was quite late as there was no pilot Crew is usually excellent, this flight not as good as usual there were more mistakes, slower and less friendly service But honestly the aircraft was too cramped and uncomfortable for a 4 hour flying get so, do to the aircraft liability the very best you could ever do is mediocre.

Absolute disaster. Rude, uncooperative staff. Staff ignores and pretends you don’t exist when you are asking them a question. Erroneous departure gate and baggage claim information. Equipment not working for purchase of drinks. Overly expensive baggage check-in fees. Overly crowded. Dirty airplane. Passengers coughing incessantly as if they were being gassed. Circled airport in flight several times and waited on the tarmac for 1.5 hours. The worst experience ever. Consider another industry. The travel industry is not for you.

The pairing of personal Bluetooth headset did not work, provided headset did not work, then the screen locked and therefore no in-flight entertainment was available.

Our flight was delayed several times. It left 9 hours after scheduling. We had to sleep in the airport.

This flight was 2.5 hours delayed due to crew issues. This meant that we arrived after 2 AM. Very very inconvenient and we were not really kept well informed.

United is today and old, the planes, the staff, the business processes. Yet they expect premium prices for a less than average flight experience. I should have remembered to stay away from them and will remember to stay away from them in the future since I'm traveling a lot again. In a nutshell, they suck eggs.

The entertainment wasn’t playing in the app or online.
