Very nice as always. Not that it’s anyone’s fault really but for some reason the seat (16C) was really hard…. Not typical for your planes… dunno what or why… maybe it was just me ?, The flight was great otherwise

Very nice as always. Not that it’s anyone’s fault really but for some reason the seat (16C) was really hard…. Not typical for your planes… dunno what or why… maybe it was just me ?, The flight was great otherwise

My experience was great with Alaska Airlines. They were very helpful when I was checking in. The flight crew was very helpful with our needs.

Crew members were friendly, but I wouldn’t use “entertaining” to describe them. Exact step by step instructions on getting wi-fi on the phone would be helpful.

Ease of reservations, confirmation. Cramped seating, very, very uncomfortable! Claustrophobic.

My husband unfortunately had a very large lady next to him who did not fit in the seat and had to have the armrest up so she was partially in his seat and she also had horrible BO

I liked the legroom even in row 26! I fell asleep immediately and slept the whole flight.

delayed flight 3 hours, then took 45 min to get to gate and another 10 min to open door

The plane was put out of service and had to wait for a new plane to be assigned. No one had any information and the information on the screens was never updated. The call wait time was 2 hours and the estimated time for text assistance was 55 minutes which was a lie because after 55 minutes nothing happened. I understand that delays happen but to not have anyone available to provide any update or reassurance was just negligent. Also, what is the point of having an 800 number if no one answers it and don’t get me started on the text message system. Ridiculous!

Very good; ohana atmosphere and taking care of customer care

Flight was delayed an hour, so that was inconvenient. But they tried to make it up in the air, which I appreciated. Crew was very nice, service was excellent. Description of food didn’t quite match what was served, but it was tasty. 👍🏽

My experience on any Delta flight is always overshadowed by the time Delta removed me from a flight for no apparent reason.

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

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.

The flight was supposed to leave at 7:30pm, but departed 10:50pm. They kept moving departure time out every half hour. It was a 45 minute flight from n Sunday night with great weather.

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.

The crew was great, the food is decent for airline food, and we flew economy but the seats are comfortable and had plenty of room for my 15 year old son and myself. Would fly Hawaiian Airlines again for a long haul flight in a heartbeat.

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.
