Our flight when we finally got rerouted to a different destination than we were going was fine. But 2 days was taken out of our vacation because our flit was cancelled. We understand mechanical problems and of course don’t want to be on a plane that has mechanical problems.Wish there had been another solution.

Kayak wouldn’t refund me for a flight I was trying to cancel through Kayak. Alaska airlines said I had to cancel through Kayak. I called the customer service line and they couldn’t refund the flight that I booked through Kayak either. You stole my money. You will be hearing from my lawyer.

The bathroom trash container under the sink fell out and was like that long before my flight. The plane smelled of canned fish and floor was Deteriorating

I behave had better flights this one was old and poor

See previous. It was the flight from Honolulu to Kapalua that was cancelled.

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.

Good. Flight was good. Crew was good. Wish they offered coffee refills. Wish I didn’t have to pay for headphones. Otherwise good for a commercial flight.

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.

I didn’t order food so can’t really say how it was. Overall, it was a great experience.
