Great staffing. Terrible food. Please do cold sandwiches or salads. the "hot pickets" are terrible.

Love Hawaiian you can’t go wrong, still provides you good drinks and little snack at the end

No tv’s. Had to walk 45 minutes to connect to next flight. Couldn’t get dinner as a result. Ended up eating pretzels until I felt sick.

Not so good. The takeoff was aborted after reaching 100 knots due to a problem with the front tires. I do commend the pilot for a quick decision and preventing a potential disaster. We returned to the gate to put fresh tires on the front. Our flight was delayed for over 3 hours. The rest of the flight was okay. We were reimbursed by Hawaiian Airlines for only $50. Not too generous

Great plane, seats, and crew. Super smooth experience and delicious coffee

Liked the staff ! Seats a little uncomfortable for a 9 hour flight. Wife ‘s monitor at her seat didn’t work. Food was disappointing. Snacks were good . Choices of movies and music could have been better.

Arrived at the gate with no seats assigned. Was told by gate agent the flight was full and we would not be on it. I asked the gate agent how could I be sold tickets when the flight was full. She replied, “Thats just how they do it.” I was able to get seats once I arrived at the gate. The flight itself was great. I’ll never purchase tickets without seat assignments from kayak or anyone again. Shame on kayak or Hawaiian airlines or all of you.

The pre-flight check in process was bad. The app didn't allow check-in online and forced me to check in at the airport. Alaska didn't have self-service kiosks for check in (only bag tagging stations), so I had to wait in line with people who were checking bags just to get my boarding pass.

Hawaiin airlines never let me know the alaska airlines confirmation number. it took chat and call with customer service to get that.

Flight delays, another inconvenienced passenger, and crew serving food and drinks with hair not tied (really very messy - made me apprehensive taking any uncovered food or drinks)

Their aircraft are old and amenities lack way behind other international carriers leaving from BNE. Even in economy

Airport and crew experience was excellent. We had to queue for the runway - no one’s fault, but it did mean we were 30 minutes late leaving

Overall good experience with flight and airport wheelchair staff. Also got Indian food in the flights

Friendly staff, surprisingly good premium economy seats allowing good sleep/ snooze opportunity and very good menu.

Very good as always, stand out airline. The passengers whom choose to stuff baggage that otherwise should be checked-in is a real bother but that's not the airlines doing. A real frustration that passengers just don't want to check-in luggage. This is a pet hate unfortunately.

It’s a two prop flight so I had problems with my ears on re- entering ! But otherwise fine

I love flying with Qantas. There was no onscreen entertaining on this flight, and only a snack provided (not a meal) but still better than Jetstar or Virgin (in my opinion) so still happy.

Complaint is with American Airlines which delayed our flight from salt lake to Dallas reaulting in us missing our connection to Brisbane. Had to spend 24 hours in Dallas to wait for the next flight. Awful experience and ruined my wife’s birthday.

Wheelchair assistance to move through the terminals and to/from the plane door was excellent. No vegan snack on the flight, only something with salami and cheese in it.

The old Plane had not been cleaned properly in a long time.

Multiple delays and not straight answer from the United team

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

leg space better than expected. two washrooms for one plane isn't enough.

My suitcase was destroyed. The top part where the handle is is completed broken. And unusable now.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

We missed our flight. The boarding pass had the wrong gate and by the time we received the text from Kayak, our flight was already gone. I’ll never use Kayak again and will go direct to the airlines in the future.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Cabin felt crammed Snacks are lame But crew was super efficient getting us out on time despite delay

Flight was delayed bc of mechanical issue. New plane had different configuration so some seats had to be switched. They called all passengers who needed new boarding cards. They did not call us so we thought our seats were the same and fine. When we boarded they informed us our receipts had changed and we are now all sitting separate and in the back row. Both my daughters had meltdowns and started to cry and once we got on the flight, we figured out how we could sit closer to each other, but this was very upsetting.

Took off on time and successfully avoided weather that looked to be a problem along the way

There were five broken seats on the plane. The crew was very rude in telling people they had to get off the plane and get a flight the next day. No call for volunteers, but telling people they had to get off. One woman was flying with her elderly mother and daughter and was told she had to leave or all three had to leave. Fortunately, a volunteer offered to stay. The situation was handled poorly.

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

Any sort of gluten free snack option would be nice

They lost my luggage and it didn’t get delivered until the next day.

Would have thought that they would gas up plane before everyone got on board

Short flight so no food or entertainment. Good landing at SFO and on time. We were told no carryon luggage yet lots of people were puting bags in overhead compartments. The rules need to be made more clear. I was on the first leg of an international flight and this is the first time I could not have carryon luggage.

My flight was overbooked and they would not let me board. I had to book another flight and pay the full amount of that flight. I did not get any help at all from Air Canada or United Airlines.

Comfortable seats and movies entertainment available. Better experience than the flight from Toronto to Denver.

Overall good experience. The flight from Toronto to Denver does not have entertainment - movies to watch.

There is not enough space between two chairs and raws.

Everything was made rather simple, so I appreciate that. All the people I dealt with from entering the airport in Jacksonville to my lonnnnnnng walk to my next gate in Chicago were excellent and very helpful.

Crammed in like cattle waited 30 mins for late connecting flight (flight didn’t wait for me for me when I missed my connection at 2 different airports on outward journey)

Terrible. 3 missed flights and 24 hours delayed with lost bag and promised $100 compensation from United and absolutely nothing from them…

It was a lovely flight. Very attentive crew, comfortable seats, good food and entertainment. Highly recommended. Only difficulty was with their app.

Terrible. Flight was delayed for hours and we ended up arriving at our home at 4am after 20+ hours flying.
