Alaska Airlines has horrible customer service. After sitting in a packed airplane for over an hour, they decided to cancel our flight and had us deplane. Instead of helping us nearby, we had to ride two trains (in Seattle Airport), from the S-Gates to the C-Gates; only to stand in a line for 3 and a half hours. Throughout the 3 hours, there was often 1 agent at the customer service counter to help the passengers trying to get information and accommodation on a flight that they cancelled. Do better!

Short trip from Honolulu to Kauai. Not a major issue. Only concern was the drop off of the luggage for departure. Only one person handling all of the passengers. She was busting her butt.

I know airlines have to save money, but a little more legroom would be nice. I’m a small person and I just felt cramped after a few hours. However, I loved everything else! Free Alaska Airlines wifi, free movies, yummy snacks, and the crew was so helpful and accommodating!

I love the flight ✈️ Hawaiian Airlines. All stuffs are fantastic members ♡ sweet hearts and families warm welcome 🙏 I have milage of Hawaiian Airlines members so get points .also I booked kayak agent got cheap price ! I satisfied flight with Hawaiian Airlines ♡ thank you

Good, but because I fly internationally I found the food and service lousy compared to European standards. You should include a regular small mean (and not a lousy sandwich) and ear phones. People who travel from Europe are not aware of limited services.

Confusing now Hawaiian and Alaskan have merged, hard to check in - they need to uncomplicated things.

Should have been forthcoming for reason for delay. Should have been able to check in for seat I'd like.

It was fine. It was a 30 minute flight so there was water or fruit juice and no food. Which was totally fine. The check in, gate and flight crew were all excellent.

Check in online didn't accept my confirmation number so i could only check in with assistance at the airport and ended up with s creepy middle seat.

It was the most expensive Alaska Airlines ticket I’ve ever purchased. I had a middle seat with no legroom or space compared to any other middle seat I’ve hadThere was a silver box under the seat that took up 70% of my legroom on the most narrow 737 max the crew flat out would not help they would not help with bags they would not help with garbage there was no coffee,It was definitely not one of my better experiences on Alaska.

They sent a notice that they were boarding an hour early. We had to leave the club and run to the gate. They said sorry, that came from corporate and was a mistake. They did not have enough seating because the flight before it had not taken off on time. They moved our gate and delayed it for an hour.

The boarding and seat assignment system no longer works for me, but I know it is being replaced. Otherwise, I am good with the overall experience.

The lead steward kept singing about "San Francisco" and hotel California---more annoying than humorous....needs work. Flight was smooth and on time.

Still a fan of open seating. Flight was on schedule and arrived on time. The 737 MAX is very comfortable.

Airline travel is always too cramped to really be pleasant, but the cabin crew on this flight did a pretty good job of making up for it by putting on some music during boarding and sprinkling a few funny remarks into the safety briefing and announcements, and just generally being friendly and helpful. It definitely reminded me of why I prefer the in-flight experience on Southwest!

No delays and arrived to destination 30 min early. Staff was super friendly.

San Diego airport is brand new, spacious, airy and very smooth checkin at SW baggage drop.

It was rough. The staff was unprofessional, the choice of on board drinks terrible, it was cramped in space at every airport, they always ran out of overhead bin space so they pressured people to check bags for free or we couldn’t leave on the plane— so I did check my bag to help, and they nearly lost my bag. My bag did not arrive on the luggage belt, another man on my flight and I had to waste our time going to the baggage office to search for our bags. I would only fly southwest again if it was my last choice. Also, my flights were consistently delayed over and over again— at one point they straight up told us we were waiting for the pilot to arrive.

Crew could have been friendlier, maybe I'm spoiled by SW crews. In flight wifi was good. Would be nice to have more food offerings on a 4 plus hour flight

Had to get off plane from prior flight even though I had to reboard same plane to continue to my final destination.
