Plane was delayed getting boarded and then again delayed in take-off order. Alaska Airlines must have very little clout at JFK so they don't get priority treatment. All the delays meant we missed the last flight from Portland to Eugene. Alaska did give us hotel voucher for the night...but sent us to a downtown Portland hotel rather than to a nearby airport motel which made for a longer ride at night and then again in the morning. Just made an already long, late night even longer. Hotel was an old outdated Hilton in a slightly seedy part of town. Alaska gave us Lyft vouchers for getting to the hotel, but the return voucher for getting back to the airport in the morning didn't work.

Alaska gave us Lyft vouchers for getting to the hotel, but the return voucher for getting back to the airport in the morning didn't work.

Not a fan of a 5 hour delay. I received a text from Alaska Airlines advising I would get a $100 travel voucher via email. Several days later I still haven’t received it.

My email notifications were silenced, so I didn't get word that the departing flight had changed gates. It wasn't until I noticed that few people had gathered for the flight that I checked the airport schedule board, 20 minutes before boarding. I then told several people at the old gate of the change. If I was to receive a text I would have been notified of the change earlier, Or to hear an announcement over the airport intercom.

Canceled flight. No communication of this prior. Rescheduled to next day. Our good seats we purchased months ago turned into last row middle. No apology, reason, nor compensation for time and $ spent.

Friendly staff, everything went smoothly. Gluten free snacks would would be the cherry on top!

There was no entertainment - perhaps they need to upgrade the planes that service a route that is more that 2 hours long? Otherwise, everything was perfect.

The most comfortable plane ride I’ve had in quite a while.

Wonderful staff who honored sleepy overnight travelers and still met needs quietly and quickly!

The setting on the loudspeaker was painful and the crew member who did the talking spoke very quickly and repetitively, with extra little jokes that were distracting and mostly unfunny. I doubt that the main messages penetrated the noise.

1. On time flights. All of our, three separate, flights for three families were late 2. No food on the 5 1/2 hour flight. A substantial snack would have been good. 3. Seat upgrades are expensive 4. No place to move around or stretch on the 5 1/2 hour flight

Delayed and took off even later than the scheduled delay time

For a 69 year old with health problems I had the worse experience, no wheelchair when I entered a lady told me to sit and wait while a gentleman told me I had to walk to the Delta station, which I did. I had a carry on and a bag, and I was traveling with my service dog, which was on his carrier and the lady charged me for my carry on luggage, beside all the waiting cause of the delay, I had to walk to get my luggage cause no wheelchair showed up, I am so disappointed. I will get in touch with the company. I got home at 3:00 am, not good for my health situation.

Great experience on Delta. Staff from baggage check to flight attendants were very courteous and professional. My only issue was a personal preference for pretzels instead of the chips and cookies that were offered.

There was no problems, just a little uncomfortable with seats that do not lay back a little

Always good but we must do something about people in rows ahead of you that don't put their seats back up when they are suppose to. And It's rough to not be able to even lean over to get something out of my purse.

Flight was delayed, 30+ bags had to be gate checked. Crew were very friendly!

Everything was good until we were boarding our connection flight in Atlanta, we were told to gate check our carry-on, but when we got inside the plane, there was plenty of room in the overhead.

Did not know my son and I had different seating arrangements. He was fine, but it was disappointing.

Flight was canceled, and no effort was made to help with rebooking, no hotel vouchers, no car transportation and minimal food voucher and most places for food were closed by the time the voucher was given. Waited for 3 hours for bags. Simply the worst travel experience I have ever had

Food was surprisingly good but the WiFi was not great

The crew was great! It was nice to have a pillow and blanket... It gets cold on those flights. I paid extra money to sit where I thought was extra comfort seating, but it wasn't,... So, I was mad a bit about that. I'm hoping our flight home will be better.

Check-in process at SEA was very difficult, e.g., how to check-in and finding where to go to check-in. Staff that helped me was friendly. Security process very disorganized. Stopped at gate C2A to try to get on an earlier flight and four staff didn’t acknowledge me, some of the worst customer service I’ve experienced at a gate counter.

Flight got delayed and it was very inconvenient . Had to come with another carrier. Had to spend one more night in San Francisco.

Logging into next flight was an issue as I never received a confirmation code

Alaska airlines is not what I expected Very disappointed Unfriendly Discouraging Very bad customer service, heartbroken trying to explain to them my situation.

I could not check in ahead of time. Kayak did not give me a proper confirmation number to check in.

I loved flying Hawaiian Air! We didn’t pay to sit together, but we were able to anyway. They had usb charging ports and even outlets in some seats. They served a hot sandwich that was not very good, but we were still pleasantly surprised. The staff was very nice. The seats really made my booty hurt but maybe I’m just not used to sitting so long. Also, the AC was really cold even though I was wearing pants, a hoodie, and a light blanket.

A second drink service on a 6 hour flight would have been helpful.

The steward staff was particularly friendly and helpful. They smiled a lot and seemed anxious to be sure we enjoyed the flight.

Everything was good for the price I paid. Crew was very nice.
