Crew very courteous. Boarding was great. Slow to get baggage at Denver.

The crew was great! Passengers were nice. Just an fyi that I heard several of them complain that the snack was not gluten free. Many people got handed the snack and then promptly gave it back to the flight attendant. Might be good to look into another option as such a high percentage of people in CO and WA are gf. Cheers!

It's a pity we missed our flight by 2 minutes.

The flight check-in process was awful. At Seattle Tacoma Airport the Alaska employees couldn’t properly tell me how to/where to drop of my checked “ski” bag which I had already paid for. Boarding was slow and disorganized as well. The baggage claim in Denver was almost as bad with broken carousels (airport employees had to carry bags out to us by hand) taking over an hour!

It would be great if the snack were appropriate for everyone

Had more room than other airlines, it seemed, which was nice!

Changed gate but didn’t announce & boards had wrong information. Nearly missed flight as a result. Very unnerving!

Quite nice! Definitely the most comfortable seats of all the airlines, and I have travelled on almost all of them this year.

Diverted to another airport due to weather stranded on the runway for 2 1/2 hours they could’ve at least given us a bag of peanuts or crackers, but we got no food or an offer of any food. Also, the aircraft had no entertainment no TV movies nothing and unless you had your own reading material, you were left with nothing to do.

Our flights using Alaska Airlines went great! All of the flight attendants were very friendly. Big shout out to the pilots for getting us to and from our destinations safely!

The crew at Hawaiian Airlines was fantastic. Kind and hard working. The pilots were great with giving us all the updates to make sure we were informed.

Flight scheduled to take off at 5.55pm but it did not take off until 7pm due to some food delivery delay.

The crew was quite good, they came by often with drinks or to collect trash. But what wasn't nice was the flight was over weigh and several people had to be rebooked. I was questioned whether I should have a seat when I was getting to it. The in-flight entertainment kept buffering and interrupting. And the route took the airplane through high winds which caused us a longer flight

Wasn’t on the flight due to Alaska cancellation…also after all the rerouting, I was going to be on a later flight that left SFO at 7:47pm, which meant an almost 6 hour layover. That same Hawaiian flight was delayed for another 2hours.

My flight was delayed three hours and then cancelled. The gate agent proceeded to rebook me in a middle seat without telling me and I was placed between two large individuals who did not fit in their own seats and instead took up most of mine. It was an awful experience.

Flight was smooth and comfortable. We were able to check a bag at counter due to full flight and boarded with an earlier group. We were there very early and didn’t hear the gate change just noticed our flight was no longer displayed st the gate. There were two other flights with gate shuffles - may be unavoidable but not desirable. First time I had to print my own luggage tag and attach at arrival. Not a fan of that process.

I received an email from Kayak with confirmation number for Hawaiian and another for Alaska. I received emails from Kayak for both my outbound and return flight to say "time to check in." Despite trying each number (Hawaiian and Alaska), I could not check in for outbound or return. It was then confusing at the airport - I hda "no place to go" to figure out how to check in. All the kiosks are marked "scan bag,etc." I wandered around with no agent to talk to. That was a bit stressful. Either Kayak, or airline, needed better communication on what to expect and to do.

When I purchased my ticket, it said i was flying with Hawaii airlines. Which is now operated by Alaska. Naturally I went to check in with Hawaii airlines once at the airport. However, there was no one at the desk until 7 am and their kiosk couldn’t find my tickets. I went over to Alaska and they said they couldn’t help me and to wait for Hawaii. My flight left at 7:15 so I didn’t have time to wait. They even told me to ask United which was next to the Hawaii desk what time Hawaii opened. I called the Hawaii airlines number and the operator told me to ask Alaska for help since my flight was operated by Alaska. So I went back and almost got brushed off again and sent to Hawaii. The Alaska desk attendant told me to check in at their kiosk but it didn’t work. I ran over to an older lady who was helping check bags and asked for help printing my boarding passes. Thankful she was able to do it right away! This whole debacle took a little over an hour. I wish there was better communication and knowledge between the two airlines because it could have been easily handled if everyone between the two airlines was on the same page. Once I ran through the airport to get to my gate, we were greeted with a smile and they seemed glad we made our flight! We were the last to board and barely made it. After the headache our flight was great! No complaints there.

Biggest issue: awfully narrow seats, + not a lot of leg room. Other than that, everything was good. Cabin crew seemed like very nice people.
