Liked the flight was on time. Seats and leg room need major imptovement

Low cost, but I think I really wanted an aisle seat, and I could not easily get one. The return leg might be easier.

Flight was delayed 14 hours! We missed an entire day of our vacation and had to pay for hotel that we didn’t use

Could not check in online. Called airline twice, thinking Hawaiian Airlines could check me in during phone call. NO. In 2nd phone call, Customer Service explained that due to “transition period” of Hawaiian Airlines/Alaska Airlines merger, I could only check in at the airport. In addition, flight to Kahului was late at arrival gate; I made connection to Lihue but my bag did not, so I had to return to Lihue airport a couple hours after my arrival to retrieve the bag.

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.

When we checked in our luggage, we had to use the tray, but include this tray is extra weight. I think you should not use the tray.

I flew from San Francisco to Honolulu on Alaska Airlines codeshare with Hawaiian Airlines, with a Hawaiian Airlines plane and crew. The flight was well organized, including boarding and deboarding. The crew was professional. Unfortunately, the charging ports at my seat and the seat next to me were broken. The Hawaiian airline terminal was a pleasant surprise compared to the rest of Honolulu airport.

Window seat and a packed plane. A very uncomfortable flight.

My flights went about as good as they could be. I’ll always take Alaska when possible.

The staff were great, no screens on the back of seats and the connection for the films on your own devices, was not great.

I used by Skymiles to upgrade to First so that I could comfortably work using my laptop. But WiFi was intermittent and unavailable for long periods. I feel like I wasted 70,000 miles :(

WiFi was a major problem and if it does not work on a 4 hour flight then that lowers the overall experience

The Airline Attendant found us in flight and moved us to seats in the front of economy due to the short time we would have to make our connecting flight. We really appreciated it.

Carmen was an absolute delight on the flight staff! Everyone was lovely and made it a very pleasant flight.

Internet connectivity still seems to be touchy on these flights, making it difficult to rely on it for getting work done.

Crew was absolutely fantastic and we’re so welcoming and friendly ❤️

Flight delayed four separate times. I’m now one hour hours late to landing.

The plane was an older model, so it wasn’t as comfortable as others. The flight attendants were not helpful during onboarding. It was a full flight so there was chaos finding space for baggage.

Awesome! On time flight, early arrival, and a complimentary upgrade!

Delta’s staff is unmatched. From the gate agents, to the pilots, to the flight attendants… all top of the industry.

New Max 10, first class seats have been shrunk. End of a 20 hour journey, it was United not Lufthansa, just glad to get home

One of my checked luggage was damaged. Cracked on the top by the handle.

I have been flying united for a long time but now I’m done

Older aircraft, no meal, only food was for purchase. Not impressed United.

Stuck on tarmac for two hours plus a 5.5 hour flight. Rude flight attendant. And no meals, not even for purchase!

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.

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.

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.

Everything was great, only problem was that flights were delayed

Crew was nice and helped. But they placed my checkin suitcase on the wrong airplane so I didn’t have my CPAP machine to use for 1 night. The United attendant at HNL informed me that it’s on the next flight from SFO to HNL and ETA is 8:18PM and that they will deliver it tonight. At 9:30 PM, I saw conflicting reports , one saying it’s on the way from the airport and the other saying it’ll be delivered after 6:45 am tomorrow. So I called UA Zbaggage Resolution Center and the agent says it’ll be delivered tomorrow by nighttime At latest.
