Alaska airlines has gone from excellent to budget. Food only for purchase. Entertainment only on your devise, no headphones

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

The flight was good, there were no problems at all. The only thing that was very disappointing was how filthy the bathroom was, it was discussing.

The leg room is way too small for my 6’ husband.

Alaska Airlines is horrible. They notified 30 minutes before boarding that they needed to reroute my flight, causing a 22 hour layover and 42 hour travel experience they could have been avoided if they adequately informed me when I did online checking, 24 hours in advance, that I would need to reroute. This would have avoided a horrible experience if they truly demonstrated customer care

besides flight cancellation due to over boarding - diverted flight and lost baggage - no customer support whatsoever and 2 months of traveling lost

Great experience. Boarding was fast, staff were very nice and funny, everything at the seat worked well.

The flight to Houston the agents were not very helpful

In Liberia airport 5 min before our departure the airport was closed for takeoff for 30 min. Upon arrival to IAH we didn’t have any available gate and waited taxing another 40 min. As a result we arrived for 1+ h later. The walkway to the passport control in IAH is about 1-2 ml long. After the passport control you have to pass the security check again. Only 3 out of 16 checkpoints were open and the line was enormously long. As a result, even though we supposed to have 2.5 hrs gap in between the flights we missed our transfer. United rebooked us for the next available flight early morning and provided free hotel and meal vouchers through.

The staff was nice, however boarding taking 2 hours. That’s insane. Overall very bad experience, a lot of turbulence and when landed in Chicago was horrible. I don’t think I’ll flight with UA again.

It was good, although we could not get our preferred seats, we did enjoy the whole experience from Costa Rica. I still don't understand why our luggage is not the first to come out at the band.

Movie selection is good. Crew did not understand mileage program and were no help. Sick later. Food?

I love United was disappointed we had a two hour delay, however the Pilot did say safety first.

Since when do I have to pay for my checked bag? I have a United Explorer mileage plus silver card and I was charged for my checked bags. This also is an international flight. So I would like an explanation to be clear before I choose an airline please?

Flying to anchorage would have been cool but the weather got in the way

Boarding was terrible. My wife uses a wheel chair and she was in an incredibly hot closed metal cargo box for close to 20 minutes before getting on board
