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.

The food was terrible. And the flight attendants were very rude. One flight attendant wouldn’t help a passenger lift their carry-on. Another flight attendant wouldn’t give a man an extra blanket. And they walked by not even looking at the passengers to see if they needed a glass of water.

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.

I have flown Qantas multiple times in the past it seemed this flight the plane had less seat room or the seats were way less comfortable than before. Everything else was about the same. Thanks

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

I got upgraded from economy to business, and the experience was outstanding

Boarding was over 3 hrs late and we didn’t land until almost 1:30am

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.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

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 completed destroyed. The top part is broken and unusable now.

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

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

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.

British Airways staff are very polite and willing to help.

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

3 hours late. Not even water offered on a 2.25 hour flight.

I had a carry on and a personal bag. I put my personal item under my seat and on way to the seat I put my bag up. I usually close my eyes and rest as I was on call for last 36 hours. I heard very loud announcements that someone needs to identify their bag. Pretty sure it was not mine until the hostess pointed out my jacket details attached to the bag. I asked why she got my bag out. I got berated and did not want to create a scene. But this person needs to be talked to.

Everyone was nice. It was on time and the food was. Airplane food, but not horrible

Terrible. The flight was delayed two hours due to weather. Then when we got on the plane, the first pilot ended up timing out and we had to wait for a second pilot. Second pile came on board and we tax it out. Had to return back to the gate because of an unruly passenger. Then the copilot timed out. Had to wait for new copilot. Also had to wait for maintenance to check for fuel. Then found out the second pilot timed out and we had to wait for a third pilot. Was ready to go and then needed maintenance again for another issue. In the end, it was 2 o’clock in the morning when they announced that the flight couldn’t go because the third pilot and the second copilot had timed out.

Poor air traffic controller staffing led to a 50%reduction on flights so we got to wait 4 hrs for our flight! Very disorganized at the gate Poor communication with customers

It was delayed by almost 90 minutes and that messed up our plans but it was beyond UA’s control that is what we heard

Terrible experience, flight was delayed both ways. Limited compensation for the 5+ hour delay. Will not be flying Air Canada Rouge, and don’t recommend you do either.

The boarding was relatively quick, the crew welcoming and flight uneventful. The omission of meals on all airlines is unacceptable especially when the flight is during a mealtime such as this one, (lunchtime), is unacceptable.

Everything was simple and easy. The lady at the gate was super friendly, I wish I had her name to share. She's a little older, dark-haired. You can tell she likes her job and would be a great influence on any young people training with her.

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.

No Charging ports for personal electronics, which were required to use wifi entertainment.

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)

Rushed, the boarding was a great deal like a Chinese fire drill.

Staff was friendly helpful also good timing I rate it a 10 out of 10
