Poor customer service, no accommodation for passengers when the flight was delayed over 5 hours.

Not having a five hour delay with little notice! The crew was very kind, though, and just as tired as we passengers were. The flight didn't depart until nearly 1 am...and no reason was ever given.

Great flight from Seattle to Phoenix and to Chicago-Midway from Phoenix

The Air hostess were very rude on my flight from Houston to Austin . Their regular communication itself felt a they are shouting at people.

The charges were ridiculous for an hour flight and the turbulence was very scary.

The plane arrived 25 minutes late, and the Wi-Fi was slower than it usually is.

Flight was on time and the crew was very nice.

Flight was delayed for 1 hour. Otherwise it was a fairly normal Southwest experience

Main flight attendant made light of the delay and presented some humor to lighten the tempestuous situation. Delayed flight took off 2 hours after scheduled time.

More assistance and clarity for travelers with gate checking and lap children

Good flight, loved the snacks (Biscoff cookies). For boarding, they forgot to change the sign showing our group was boarding. Apparently, they had announced it, but the announcements overlapped with another gate announcements and no one could actually hear what they were saying. So a group of us were waiting....and finally asked and were told we could board.

overall no call for accessible while boarding. The crew member was little rude not bothering about the condition. Seat assigned was very uncomfortable.

Check in & bag drop was straightforward. Alaskair changed the gate approx 40 min before departure, and I only became aware due to Google wallet update to my boarding pass. Had to move from gate N1 to C9 which required use of the Train, luckily I had time available.

The airline staff was great! The best safety review ive ever had!

Original flight was canceled, and the automatically booked second flight was immediately delayed. I arrived about 4 hours later than planned with only a $12 meal voucher that didn't fully cover a sandwich at airport prices.

When I made my transfer from my flight from Missoula to Seattle to Seattle to San Jose, the gate was at the opposite end of the airport, which I thought was inconvenient since there were so many gates for Alaska right where I landed that everything was good

It was unexpected not to board with a jet bridge - the weather was good that day so it was not an issue. It was completely unclear what boarding group was called...there was no monitor with that info.

First class food and service was excellent. When I booked the ticket my outbound was automatically upgraded to a non bulkhead aisle seat which was much appreciated. However, my return was not. By the time I upgraded only windows on the bulkhead were remaining. It would have been nice if my seat was automatically upgraded within the appropriate advance time window so I didn't have to worry about it. (Not a big deal)

Captain on the flight and the flight crew were great. The onboarding was terrible with delays of several hours. The baggage claim was a nightmare from SJC to SEA but very good on the way back from SEA to SJC. The luggage took almost 45 minutes on top of being stuck taxiying for an hour after landing from SJC to SEA. Terrible experience from SJC to SEA. Will probably not fly Alaska again.

Flight departed 2hours late with no reason given and then the ground crew neither the flight crew even acknowledged that passengers were inconvenienced !! Alaska is no longer a good airline with bad on time departures or arrivals. 2 of 2 for me now in 7 days

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

The flight was done by SkyWest only WIFI no entertainment center are available on the CRJ

Love me some Delta. One of the few airlines to recognize and support veterans. Easy boarding, flight was on time and arrived early and the flight attendants were excellent on this flight.

We sat on the runway for over an hour before departure. That was unwelcome.

The cabin temperature was nice and cool. The wifi was not working.

Was forced to check in my small carry on, even though I informed the crew it has very fragile items inside

Food was surprisingly good but the WiFi was not great

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

Crew was not friendly when I went to request a seat change.

Comfort+ on delta was excellent room for a 6’4” male. No one issues. Staff was great. Flight was bumpy but the pilot did everything he could to make it comfortable. Internet went out half way through the flight. I am glad I didn’t pay for it. But that was a huge issue for users.

We got surprised and switched to Alaska airline. Dirtiest tray and seats I have ever board on and we travel all the time. Help desk would not help by chat as I'm disabled to get my sets assigned tell me call Hawaiian air. I call Hawaiian air was told the flights RT are by Alaska. Make it short, worse flights of our life.

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

Attendants seemed un-engaged and indifferent when asked for assistance.

My experience was pleasant. It was perfect. That is enough🥰💃💖

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

It was not a good experience. When I went to check-in one of Alaska's employees told me I had to check-in with Hawaiian Airlines, which was on the opposite side of the airport. I made my way over and when I got to Hawaiian Airlines they told me I was in the wrong place. The employee saw the look of defeat in my face and was able to get someone to check me in and text me my boarding pass. I had to make my way all the way back to the other side of the airport and barely made my flight. I think it would be very helpful for employees to be more informed with these Hawaiian flights that are operated by Alaska so they are not rerouting people to the wrong terminals. Also, clear signage in the check-in area.

The ticket and bag check in was chaotic at SEATAC. No clear communication or signage for bag drop off.

Hawaiian and Alaska are at opposite ends of the Seattle airport. Apparently, during this time of transition through their merger, only people flying to Hawaii should go to the Hawaiian desk. So, I had to carry my luggage the entire length of the airport. Alaska's desks were sort of a temporary set up behind a wall, and even after all this, they (Alaska) had a great deal of difficulty confirming that I was on the flight, or that I had paid my checked bag fee. Now, they did try to compensate for all this confusion. There was an impressive number of agents, actively engaging and working with customers - not just standing behind the counter, but going out to them with pads in hand. It took some time, but I was squared away, and was apparently upgraded to a business class seat with lots of legroom (much appreciated). I was told this transition would last till August.

I'm was impressed with their service. Everything was great

Hawaiin airlines never let me know the alaska airlines confirmation number. it took chat and call with customer service to get that.
