Almost 3 hr delay in Settle with very little information available to passengers. They boarded the plane and we waited for a long time inside the plane as well.

Almost 3 hr delay in Settle with very little information available to passengers. They boarded the plane and we waited for a long time inside the plane as well.

Food and entertainment not applicable - standard drinks and cinnamon cookies; crew did not do a song and dance for us so no entertainment. I like the slightly better leg room than American Airlines - at least it felt that way. Flight crew and atmosphere seemed more welcoming than American, too.

It was fine, mostly I was just happy to be on my last leg home. No in flight entertainment but that's forgivable since it was only a 2 hour flight.

Flight was cancelled, then rebooked on a flight that I was unable to get through since they had closed the gate.

Alaska Airlines adds time to flight time to make up for late departures. Also Alaska Airlines destroyed my suitcase and I had to buy another suitcase for return flight. Very frustrating and not sure I would fly Alaska Airlines again.

Landed and parked in back of larger jet. Cabin filled with jet exhaust. Left many with headache. I got sick to my stomach. Scrambled to find airsick bags

Plane seats are comfortable and seemed more roomy than others I have been on. Playing was clean and flight crew friendly. Passengers who have a connecting flight should however be allowed off the plane first

flights on time, flights that were leaving when scheduled..having the alaska people on the phone and most of all getting rid of the new atmos website it is terrible!!!!!!!!

Only issue was at the gate the clerk tried to get us to check our carry on bags. When I questioned the other clerk said, the flight isn't full, they are fine to carry on

All flights were on time. No crowded and had empty seats. All flight attendents were great.

I like Hawaiian, it was great that they had good internet connection across the Pacific Ocean, thanks to Star Link satellites. The seating was comfortable, ( I was in economy ). Maybe I missed it, but I only got offered a beverage once. It was a nonstop flight KOA to SMF. I would take it again next time I go that way.

Previously flown Hawaiian Airlines on similar routes, I found Alaska Airlines to be noticeably more comfortable. The seats on Alaska Airlines provided better support and cushioning, which made a significant difference on the long flight to the islands. When you’re spending 5-6 hours in the air, seat comfort really matters, and Alaska Airlines delivered where it counts. After comparing both carriers, I’ve decided to book with Alaska Airlines for all my future Hawaii trips. The superior seat comfort alone makes it worth choosing Alaska over Hawaiian Airlines. If you’re planning a trip to Hawaii and prioritizing comfort, I’d recommend giving Alaska Airlines a try. You won’t be disappointed. Highly recommended for Hawaii travel!

I received several emails about my 3:10 flight. When I showed up to the airport at 12:30 to check my bags I was told the flight was actually at 1 pm. They grudgingly rebooked me for a flight at 5:22 to Vegas to get a connecting to LAX. I did find the gate for my original 3:10 flight but they were booked. I proceeded to receive status updates and gate change information for the 3:10 flight, even though I was apparently never supposed to be on that flight

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.

The crew was EXTREMELY helpful And sweet and the flight was smooth!

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.

The Kayak confirmation number did not work for checking in the day before. I checked in at 8.30 using my ticket number. When I arrived at the airport, I was informed that the flight was overbooked, and since I had checked in late, I did not have a seat. The Next flight was not until ten PM. I called my wife, who had been taking care of our kids all weekend, and she was upset, calling me a liar and telling me to stay in SD. It turned my weekend getaway into a nightmare! I blame the Kayak website and will not book flights using your app in the future.

One hour waiting time after boarding, but arrived in time. I am satisfied
