As always the crew were super polite and friendly, sadly the weather & a minor mechanical issue reduced the quality of the flight, all’s well as it turned out. Still my favorite airline to fly with

As always the crew were super polite and friendly, sadly the weather & a minor mechanical issue reduced the quality of the flight, all’s well as it turned out. Still my favorite airline to fly with

They removed the cover off my checked bag and threw it away.

The flight was delayed out of BIL so many times that I was not able to make my connection. I was rebooked for the next day, losing a full day of my trip. I still have not been compensated as promised.

Easy check-in. Good customer service. Had to check carry-on due to lack of overhead space. Wish the airplane was configured with more overhead area so this doesn't usually happen.

I liked that the crew was friendly, we left and arrived at near scheduled times, plenty of on-board crew to handle the cabin service for the flight and I found the price of my airline ticket to be excellent!

Had no way to see what gate came in on or what gate connecting flight would take off.

Planes were on time. Pilot kept everyone updated. Crew was friendly and helpful

I have mobility problems and requested wheelchair assistance in Seattle and Anchorage and none was provided at all. Very disappointed. Only one gate agent in Seattle asked if I needed assistance boarding my flight in Seattle.... and only after three gate changes.... requiring even more extremely painful walking without assistance.

One of the best roundtrip flights I’ve ever been on. We needed assistance for my elderly mother and without fail, each and every Alaska team member was helpful, kind, and patient. Will fly Alaska again and again.

My travels went as smooth as they probably could have, I expected delays upon delays but to my surprise even with the small delays I had I was still able to make all my flights. Thanks -Josh

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.

attendents were rude and the boarding was disjointed and poor

There was an incredibly surly flight attendant that ruined the experience

After boarding the plane had to wait an hour at the for the copilot to show up before we could depart

The cabin and bathroom experience was poor as the cabin and bathroom were dirty and showed signs of an older plane that had not been updated for Customer’s, comfort and health. There was gum on my seat when I arrived and dirt spots around the fan and light controls. The flight was almost entirely full, so there was no way I could be moved from my seat. Th bathroom had the peeling paint.

Great crew. Comfortable seating. Nice overhead bin space. My app didn't allow me to check in for my flight to BOS. When I called Support, they didn't fix it, but just told me to check in at the airport. Seat back entertainment was great. Could be better if the audio could connect to Bluetooth.

I'm 6' 2" and even in economy plenty of leg room

great! appreciated the last minute upgrade to Comfort+ exit row, as well

My seat was changed without my consent. It wasn’t a major deal but annoying.

Didn’t make the flight. My connecting flight was an hour late and I missed the flight. You rerouted me thru Atlanta and I arrived in Rome over 10 hour after my original Rome arrival time. You also left my luggage in Atlanta and it took you three day to get my bag to meI spent 4 days in the same cloths, I had packed my prescriptions in the lost bag and went 3 days withoutMy heart meds.
