We appreciated that the flight attendant came through 3 times with drinks or water on the long flight..I was also glad that they were separating out recycling! I would have liked a 12oz sofa can instead of 7oz, but that's a minor quibble. The knee space in economy was also better than most of Alaska's competitors.

I liked the free snacks and drink. I liked the onboard entertainment. I did not like the WiFi cutting out in middle of my movie.

Flight from LAX to STS das excellent. Flight from DCA to LAX was troubled by the previous flight returning to the one DCA gate putting our flight in jeopardy. However another gate was arranged and that flight was a bit late, but was handled exceptionally.

You need a n/a category. Too short a flight for food. I love flying on Alaska from Santa Rosa Airport!

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.

Online check in didn't work. Somehow ended up with 2 Alaska rewards numbers and 1 for Hawaiian. No one at check in could figure out what to do. No one at check in could help me confirm an upcoming flight on Hawaiian Airlines.

Boarding process was poorly handled by the gate crew and the onboard crew. No effort was made to provide equal treatment to passengers with overhead bin space. Crew seemed disengaged and unfriendly.

Awesome. Great flight. Super nice people and I like the extra space

On time, WiFi worked, reasonable legroom, helpful staff. Unfortunately there was no water for handwashing in the rear lavatory.

My 1.5 hr flight was 5.5 hrs delayed. We switched gates twice. We planed and deplaned once. Three total planes, two had “mechanical issues.” None of this even makes sense as the original plane was sitting at the gate since yesterday evening. Then when the second plane was finally brought to the gate from the hangar, it too needed repair. Don’t worry. They gave us a $12 foot voucher. All other flights in the same area of the terminal were hours delayed. It was an actual nightmare. This was after a few hours delay on my first flight a few days ago. And I thought that was bad.

I got sick nothing contagious but distressing and the care I received by Kayla? Keighly the flight attendant will be memorable for ever. Thank You

We were told the flight was delayed 5 times, then it was moved to the next day.

The experience with American Airlines was good, although the Philippines Airlines flight was much better (better seats, better food, better entertainment options, overall better). Again, the MIA to LAX flight was fine, but nothing in comparison to the comfort and accommodations of the Philippines Airlines flight from LAX to MNL.

Loved the crew . Absolutely no complaints. Except for luggage lost

Flight delay was communicated before leaving for airport which caused it to be a non-event. Great flight and crew!

Wish some foods provided rather than just biscuit/cookie for flight more than 2 hours

The flight attendant, a black woman with curly hair who sat near Row 21, was wonderful and kind.

We are too tired and frustrated to comment politely at this point

The flight crew was rude. We were in first class and no one even offered water until an hour after we were in the air. Horrible experience

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!
