I hate it when I was forced to check my carry on and there were over 12 spots for bags in the overhead compartments even after everyone was on. So idiotic. It would be so simple for the crew to report lack of space directly instead of an arbitrary number or whatever you smart upper level people make up.

No blanket on a 6 hours red eye flight on business class. SHAME!!! Very unfair and uncomfortable especially considering how cold the aircraft was with the ac

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.

Good. They have great attitudes. I will say that the Liberia airport in Costa Rica is the best in the world.

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

Coke zero offered...good. The proptness of flight was late. This has been a everytime thing for my last 9 flights. And is putting alot of pressure on my connecting flights. Not a bit punctual. I am always early, but Ak. Airlines is not. And people i happen fly beside, parrot the same thing. The baggage delivery to baggage claim, is not prompt. Its slowwwww. The seats are poorly padded, very crowd. We need more room, not padding the airlines bottom line. Its like a cattle car. More leg room, more side to side room. And attendants need upgrade of verbal skills. I have been faithful to Ak. A., but it will change if changes are not made. Not the only planes in the sky.

We were very late to take off, late exit plane, and luggage took a long time.

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

I flew from Santa Fe to Denver to catch a flight to London and the transfer of my luggage on arrival at Denver to the London flight worked perfectly. The crew on the ground and on board for the London flight were so friendly and efficient.

Boarded early; and arrived home 40 mins early. After a long flight, it’s nice to be back home early. These flights have no amenities; no snacks. So need to bring your own

Boarded early, left early, arrived 40 mins early! A win win for me!

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

These airplanes should be illegal. The seats are two tight, it is a safety issue. Wheelchair support was ridiculously slow. We almost missed our flight.

It was a short flight so I was expecting too much

Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms

Flight was delayed but more than 90 minutes. This caused me to miss my available windows for pick-up by a friend. I had to pay $125 for an uber back home from the airport which was an added expense that I had not budgeted for my trip. Staff was friendly.

Uncomfortable plastic seats even in premium economy. No free wifi. Even paid wifi was spotty to nonexistent. Bad food. Much worse than economy on foreign carriers like Qantas.
