Delayed flight both ways. Then, on the return flight, we were stuck on the tarmac for at least 30+ minutes. Idk what happened, but this was a bad experience.

Delayed flight both ways. Then, on the return flight, we were stuck on the tarmac for at least 30+ minutes. Idk what happened, but this was a bad experience.

Great flight, no bumps to speak of, pleasant crew, good inflight entertainment choices

Coffee or tea service would be nice for an evening flight, water or juice not good enough.

this flight had a 7 hour delay due to weather in NYC. It diverted to Pittsburgh for 2 hours then proceeded to NYC. Through it all the crew and flight attendants were terrific. They gave timely information, showed empathy , and were very professional.

Paying for first class and then they want $8:00 for wifi.

fine. only problem,,,, for some,,,,was that many people started trying to exit from the back of the plane,, . lots of irate people. there should be a flight attendant mid plane..to be sure that doesn't happen. The crew up front had no idea what was happening. One big guy started it..then a bunch of others followed his lead. could have gotten ugly... One man stepped in and questioned those rule breakers.. nothing bad happened,,,but......

Big delay of over 7 hours on next leg of trip with Alaska. Would have been nice to have food or something

We were late so that was what was worst part

Flying on Hawaiian Airlines was good. But, getting a boarding pass was a hassle. I booked what I thought was an Alaska Airlines flight that was actually a Hawaiian Airlines flight. I couldn't check in online. I had to wait for the Hawaiian Airlines counter to open so I could get my boarding pass which was a requirement for me to get in The Club or the Centurion Lounge. (I had no check in luggage so I didn't expect to have to physically check in.) The Alaska Airlines staff blamed the FAA for the problem.

Great, overall. Thicker seat cushion would be nice. My butt hurt the whole flight.

Flight got delayed and it was very inconvenient . Had to come with another carrier. Had to spend one more night in San Francisco.

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.

Thanks to the supervisor Jose my pregnant wife and our family will not miss a very important ultrasound tomorrow. What he did was simply heroic. He needs to be promoted and praised. Please tell him our family appreciates him so so much!

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

Flight was canceled with no voucher of any kind and next available flight was two days later.

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

On time. Alaska upgraded seat comfort with memory foam seat covers with head rests

I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.

The best airline I have ever travel , really good customer service, attention and service !!

Everything was great. Only thing that could’ve made it better was buy on board options for hot food, but the snacks were decent. The flight attendants were great. I had no complaints. I was able to make it to my destination safely

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.

Flight was late as pilot crew had to land at different airport in their previous flight. Passengers boarded and had to wait for pilots inside plane. Series of incomplete and unnecessary announcements by an annoying voice, rather than complete, informative announcements.

Breakfast was not loaded at SFO due to catering company change. Seems like a major airline at a major hub would have thought of something else or warned passengers to pick up food before boarding a 3 hour flight.

Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.

They hired a new catering company the same day of my flight. They botched the job by not delivering the right carts and after THREE HOURS waiting, the flight crew timed out (flight was 19 hours long and FAA rules state crew can’t work more than 14 hours long). So they CANCELED OUR FLIGHT!! Worst experience ever. Avoid UAL at all costs.

The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.
