Airline reviews

The jet bridge electricity was out. We were boarding in the dark. No air-conditioning and it was extremely hot. Every person that came out of that jet bridge into the aircraft was profusely sweating. Truthfully, sitting in first class, it was no Hawaiian hospitality. Just a bunch of senior flight attendants are doing their routine over and over.

The jet bridge electricity was out. We were boarding in the dark. No air-conditioning and it was extremely hot. Every person that came out of that jet bridge into the aircraft was profusely sweating. Truthfully, sitting in first class, it was no Hawaiian hospitality. Just a bunch of senior flight attendants are doing their routine over and over.

The in flight speakers little touches of humor were entertaining.

No food or entertainment because it was a short flight. Unfortunately the takeoff was delayed more than an hour

The flight left and arrived on time. the only food offered on the 5+ hour flight was a cheese sandwich. Unlike Alaska Airlines there was no information on the website regarding food at all or any option to purchasse in advance. Otherwise, it was an excellent flight.

We were not given the seats we reserved. But helpful attendant at gate gave us very nice seats.

The flight was very smooth and comfortable. The entire flight crew was very professional and provided excellent service. Thank you.

It was great with the exception of a rude desk member on the way back. And a terrible sandwich on the way back.

One of the best flights Ive had in a long time

My tray was broken and instead of being moved I was provided blue tape.

Terrible. Unfriendly, couldn’t care less crew. Left lights on entire time for 10 hour flight Departed at 5pm local time. Captain made one announcement entire time. No information given and clearly not interested in letting anyone sleep with lights up. Food served was poor. Entertainment was poor. No WiFi choices on screen backs was dated and cheap. Seats and amenities were dated and barren. Hawaiian used to get by on their service/aloha, but that’s been out the window. Even for local interisland I fly only southwest as they are far superior. Very disappoint in Hawaiian and this flight.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

Flight was delayed due to the late arrival of the catering truck, which is quite unacceptable. There was a beverage service, but no pretzel, or cookie, or nuts were served in coach.

Flighty delayed on boarding - then group 1 had to check their carry on bags but groups 3 and beyond could carry bags on - very inconvenient for weekend business trip with no checked baggage. Then delayed on the runway - before take off. No communication from pilot on why or how long. Wifi/Entertainment didn't work for 4+ flight. Upon arrival, attendants announced wrong carousel for baggage claim - everyone was waiting at the wrong place for their checked bags. This was a mess united!

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.
