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.

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.

The crew in first class did an amazing job keeping me comfortable, well fed and with plenty to drink. They work hard and deserve to be recognized

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.

It was a pleasant experience. Considering we paid over $3000 for first class there really wasn’t anything special about first class. All the seats looked the same and everyone got the same great customer service. The only thing that was different between first class and couch was the drinks and the meal. We wouldn’t waste that much $ on first class on that plane again.

Once again, Hawaiian Airlines upon checking in for our return flight, told us that we hadn’t paid for our extra comfort seats. This had happened on our incoming flight as well. Hawaiian Airlines had changed our flight and put us in standard seats. I sent them confirmation emails and receipts showing that I had paid for extra comfort seats and they ignored me and refused to accept my proof of payment. I ended up having to pay for our extra comfort seats again. On our return flight, once again, we were told we hadn’t paid for our extra comfort seats, which we had. I argued until a supervisor was summoned and researched further in their system and found that we had paid for them. If I hadn’t insisted, we would’ve been forced to buy our seats again or be assigned a standard seat. This kind of Customer Service is totally unacceptable. I would never use Hawaiian Airlines again if I have a choice.

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

Glad they offer free meal, & I got a complimentary drink I’d like coffee,tea, or water offered 3/4 into trip

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.

Even though we were delayed, we were able to make our connection

Starlink wifi on the Embraer E175 is an excellent experience. I was able to connect and work from IAD all the way to approach into BTV.

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

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Always wish for more healthy, gluten free options. We have to bring our own.

Having a long layover, I was very appreciative of the ability to stand by for an earlier flight. Other airlines like Delta have refused this to me in the past, just to be mean (because my ticket class wasn't high enough). United went out of their way to help me get to my destination early, which I really appreciated given that it was the third leg of a 24+ hour journey for me.

Other than a way way too cold cabinets for the entire flight, all was great

One bag is incorrect and not acceptable for an international flight. The food was not just good. I won't fly with them again.

Not pleasant trip cross country when the entertainment and WiFi system not working. No entertainment for entirety of route. Staff was rather nonchalant in that they dismissed the problem due to age of plane. It would have been nice to know this up front so I could have come prepared to read or download movies before boarding Coincidentally or not, there was a similar issue with the entertainment system on my previous flight I took on my fist leg of the trip. There are no seat TVs, so you must rely on the app when it works. United can do better. Also, what use it it to pay for boarding group 2 when half of the passengers are in the same line as you?

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

Delays to take off and to leave the plane after landing added a lot of time to this flight.

The Phildalphia to Allentown portion was a BUS, not a plane. All was as expected.

Excellent - explanations were clear staff was nice and flight was comfortable

Flight was delayed not sure why no explanation given and no apologies either. Otherwise the flight was fine

Did not get the seat I selected and paid for.

Plane was delayed for 6 hours, at first by weather, which is understandable, but was further delayed with NO given reason for 2 1/2 hours more. We had no clue when we were going to depart actually until they opened the ramp. VERY POOR to ZERO COMMUNICATION!!!

Flight was delayed and after being in the airport for like seven hours, it was canceled.

Flight delays numerous times. Everytime we would get close to boarding it would be delayed again. Strung along the entire time.

Overall very good, only complaint I have is the crew from CLT to SAT could have collected trash sooner.

Above and beyond effort from this crew in a tough situation. So helpful and understanding. Thank you!
