Airline reviews

I always heard this was a terrible airline but I was happy to experience otherwise. The seats were more comfortable than delta. They did board late and gate was a little chaotic, which is to be expected for a budget airline. I would definitely do it again for that price.

I always heard this was a terrible airline but I was happy to experience otherwise. The seats were more comfortable than delta. They did board late and gate was a little chaotic, which is to be expected for a budget airline. I would definitely do it again for that price.

Very expensive for short flights. Can’t communicate with Alaska Air about passport issue at check-in. Also no replies to my text messages. Wanted to extend our vacation for two more days but this expensive flight ticket is called SAVER and I couldn’t make changes or cancel or get a credit even, so I paid another airline for the return trip. Extremely disappointed.

They canceled my flight then changed me $155 for the same flight the next day

Our flight time was drastically changed which caused us to lose a day of vacation

I like the new adjustable headrest. Unfortunately 2 crying children were in front of us. But it was the first time and not holding Alaska accountable for that. Alaska always seems to have everything in order professional but comfortable.

Very bad, terrible food and late by 2 hours. Then no to open aircraft doors

The plane was delayed a bit. It wasn't a huge problem though, as we were heading back home.

Flight was great. Boarding was crazy because another flight was boarding late next to ours so everyone was standing and in the way.

very good but no blankets for overnight flight or tv screens…

We were in 1st Class. Excellent service. Easy boarding. No too difficult to speak with someone on the phone. Breakfast was not eatable for me. No screen to watch movies. I don't have or want a tablet. This is first class there should be screens. Even if I had a tablet there was no place to put it. There is a place to put a tablet in economy. Seats were a bit lumpy.

Delayed flight. Nicest crew member was a SW pilot flying seated next to me who kindly move to seat the final passenger. Flight extra delayed. My cup of refreshment of ginger ale was so packed with ice it was literally 2 sips.

No trays in our seats, we sat in first row, purchased a business class fare. Had to hold our drinks and snack in our hands. No plugs for our cell phones. Had to pay for it a drink cocktail each. Seats so uncomfortable.

Flight wasn’t even full, but too many carry-ons caused us to run out of bin space. New bag fee has folks who would usually check their bags carrying on. Watching Southwest morph into Spirit/Frontier is so sad to watch

Southwest is Southwest. No frills. If you're luck enough to get a happy crew (we did), then it makes for a nicer flight.

It was a perfect flight in all aspects! Both legs!

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

I liked the crew member who gave flight instructions on "in case of a problem:. The seats are so small that only a young teenager could sit in middle seat.

Great flight staff. Ease of boarding. Overall, very uneventful and easy trip.

Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.

I recently flew Southwest from San Jose to Honolulu. I was very impressed with the flight crew, especially the flight attendant in charge of the front of the plane. She came through the aisle at least five times for drinks and water, and two times for snacks. I have not seen such service since I flew first class. Also, for the first time, they gave us the correct baggage claim number, and the luggage came out quickly. I can't wait for Southwest to have assigned seating! I absolutely hate the Cattle Call boarding procedure and the mad dash to get seats and overhead bins. However, the boarding was efficient.

The worst flight experience I've ever had. Our flight was delayed 14 whole hours because the flight crew never showed up. We had to wait in a two hour line to get our new boarding passes, we were told we had no other option but to fly at 10pm (we didn't depart until 11:45pm). Everyone had to contact their hotels and car rental places, workplaces, etc. since we lost an entire day's worth of travel. The crew showed up at 10:15, which was past the time we were supposed to board. They were laughing and being completely smug when they boarded, and they took another hour to board us onto our flight. The flight crew never came to check in on us, we were quickly given one drink and sandwich and they turned off the lights and were negligent the rest of the trip. My mom asked three attendants for a seat belt extender, they never brought one. I was dehydrated and never received another drink. They were very rude and unfriendly, we had been up since 4am the morning of our flight and didn't land in our destination until 2am the next day (5am local time). This was unacceptable service and treatment, these flights are not cheap and we were inconvenienced out of an entire day of travel. This was 100% avoidable and was the fault of Hawaiian Airlines, and their crews inability to show up to work on time.

Loved the leg room, usb charging, outlet, food, staff. The seats were very uncomfortable for some reason and made my buttocks ache and would have liked to be seated together from the time of purchasing tickets without having to pay extra.

Usually we have a pleasant trip on HA. Not this time! All stewards were unpleasant, rude, rushed, condescending. First step onto the plane, WE greeted the crew with an “Hello!”. They greeted us with a terse smile then ignored us. Not a good start. Even over the PA announcements, they were rushed and unpleasant. One Stewart even berated a passenger in front of us when all they asked is if the purchase cart had vodka to purchase. The steward said “LIKE WE SAID OVER THE PA, THIS ONLY HAS FOOD OR BEVERAGE!” Vodka is a beverage! It was a legitimate question. Not sure why she treated the passenger this way. Taking trash was even unpleasant, No “Thank you” or at least a smile. I work in CS. I know good CS can make or break your trip. There was absolutely no “aloha” on this trip. All clearly did not want to be on this plane and felt strongly that they did not want to provide a premium service to their clients. This might be our last HA and cancellation of my HA-MC if we are treated the same way going home. We are typically treated with kindness and warmth in the past with HA. This trip was unacceptable.

Overall it was a good flight, but the food should be looked at. No options. The seat was also uncomfortable and very tight.

I was unable to get a check im and get a boarding pass. I tried at the desk of the flight operator Alaska, was told to go to Hawaiian and almost had to go back to Alaskan. In the end inwas told to go thru security and directly to the gate without checking in. It would have been more helpful to have the details rather than walking all over the terminals trying to check in.

We were delayed at the SD gate for close to an hour before we were allowed to depart for SJ. Reason given was inadequate ground crew to move the plane from the gate.

Your crew shortage delayed departure by an hour resulting in us missing an event we had scheduled for that afternoon outside of Fresno.

Check in process was a mess. Long lines, equipment malfuctioning. One line for baggage tags then a second line for bag checkin.

It was very pleasant. The staff and crew are very polite.

Despite two calls as well as a chat on the website, Alaska would not add my TSA number to my reservation. The flight was switched from Hawaiian to Alaska which caused them to mess this up in the first place
