My flight was delayed 2 hours which led me to lose my connection. As a consequence, I had to spend hours changing flights and hotel reservations to arrange my arrival to Vancouver.

No Free Wifi and the flight was a tad late.

The plane was clean. They got us to the destination. It was very difficult to hear the announcements at the gate. The person was speaking way too quickly, and the sound system did not carry to all parts of the seating area at the gate. The flight left more than an hour late, which left many of the passengers missing connections.

The flights left both airports on schedule. The flight from Idaho Falls to Seattle was a typical commuter trip. The flight from Seattle to Maui was not good: It was too long for a flight in a single-aisle plane and too cramped. I kept asking myself if I would ever visit Maui again if airlines continue to run this long flight like a typical short commuter flight. I am not looking forward to the trip home.

The chicken salad was very small, the lettuce was wilted and there was no flavor. The hamburger was excellent.

Mid flight we were bothered by a bee. Kind of odd, but a bee allergy made it a bit stressful. Attendants passed by our aisle during service multiple times. Otherwise, it was fine.

5 1/2 hour flight with no food service or options is inexcusable.

Mostly good. Delayed which in my experience so far happens often with Alaska Airlines. Thank you.

Excellent overall, but had to wait 30 months while taxiing. In fact, I’m still on the plane now!

We received a check-in reminder the day before the flight, and it listed the flight at a later time. Correct flight number, same seats, etc. for 3 hours later. I called the airline to confirm and they had no record of the email. The info was wrong, and we would have missed our flight if we'd assumed it was correct. I want to know where/how we received this incorrect info.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Check in process was terrible. Lady at counter didn’t know what she was doing

Delayed and took off even later than the scheduled delay time

Food was surprisingly good but the WiFi was not great

Easy boarding with an extremely kind attendant. Seats were spacious and we had 3 seats for 2 people so we could stretch out. Comfortable air flow and very attentive and hospital attendants. Bathrooms and food were the only negative. Bathrooms were so small you could hardly get in and close the door. I don’t think an obese person would fit or a person with a movement disability. Food was the trending food for flights, nonexistent. We spent $40 getting sandwich and snack at airport for our 6 hour flught.

There was a security issue at the airport and we were unable to land. We circled endlessly and then landed at another airfield for fuel. We then circled the airport again, almost landed but didn’t fully touch down before circling again. I am thankful to the crew for keeping us safe- the issue was the airline and staff at the airport getting us seats on our connecting flights. That part was hours of searching for someone and getting in double my steps.

Boarding was organised and relaxed. Crew were fantastic! Seats were lacking padding causing butt pain and stiffness.

Food from the flight from Atlanta to Santiago was very poor..

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

First class ticket. They ran out of food and I sat hungry watching the others eat

Like the ample leg room. May as well not bother with snacks if it's only a two ounce bag of pretzels. Didn't use the entertainment option. Was there one?

Agents talk too fast over intercom. I know it’s memorized and we’ve all heard it before. Just slow down a little. Stop charging for checked bags. I was pleased to get my bags promptly at each end of my flight.

It was clean and the crew was great. I wish the chairs could recline just a little more and you would provide small pillows for people with bad backs. My back is fused and a little support would be great.

Boarding was fine, but once on we waited for 45 minutes to take off. This caused me to almost miss my connection. Once the second flight was boarded we waited again for 20-30 minutes to take off.

It was pretty good except there was no food, which was understandable because it was a short flight but I would have liked to at least have a snack; otherwise it was great. Staff/crew, great. Thank you

I was on Alaska and its backup airline. I was scheduled for wheelchair service but ON ONE SHOWED UP. When I asked, desk attendant said they didn’t have any.

As noted above, getting on to the plane was rushed and upsetting since no boarding passes were available to me prior to boarding. Others were in line waiting as well. The flight and experience itself was fine. Very large plane. Two seats near windows; 4 seats in the middle aisles. Good leg room though and comfortable seats.

The trip was fine, however once we reached Seattle, our next flight only had an hour turn-around time and we had to cross the entire Seattle airport, taking three shuttles. Once there, Alaska/Hawaiian Air had still not issued my boarding passes to us and we had to wait at the counter for them. Boarding was already started and at the second to last seating level when we finally got our boarding passes. This was a bit nuts.

I am disappointed with Alaska. They are just like the cheapo airlines, nickle and dimeing us for everything. We now have to pay extra to pick our seats? Really?
