Flight was canceled. I was not alerted. It was only kayak that alerted me

Flight was 2.5 hours late leaving. We spent 50 minutes of that sitting on the plane with no explanation. They did reduce the time in the air so we arrived a little less late which was something. The cheese and crackers were okay but the wine was terrible.

Couldn't access entertainment on app as said in an email

Excellent as always, I won't fly to Australia, and back to the US on any other airline. The flight crew is always top notch, and have a way to make one feel extra special. Thank you for your service, I would rate Qantas Airways a 10+.

After already paying for excess luggage prior to flight, i was advised AT check in that i had to pay $816 or forfeit my flight! The lady at the counter was SO rude and had already started offboarding me when i said i would pay it after asking her three times for the exact amount! Have lodged a formal complaint yet heard nothing. Will not ever travel via Qantas again

A few more inches of legroom is all i ask

One of the best Qantas business flights I've had. Quality product

Business class points redemption - good value for points paid, dubious value if out of your own pocket, domestic class business product okay for this length of flight. The flight left and arrived on time, crew were good, aircraft was a bit old and tired, but still miles ahead of their competitors in Virgin and Jetstar.

Airline running better than post Covid, proper boarding process now implemented, some aircraft feeling a bit old and tired, crew fine, online experience better.

Five hour flight instead of four hours due to westerly headwinds which wasn’t the fault of Qantas !

It was nice to have gotten up upgraded to first class with a meal on a three hour flight

Not great experience - we were super late boarding due to issues with aircraft. Then when we finally all got onboard and seated and they started taxiing out to the runway they just stopped then turned around and went back to the airport. Apparently the crew “ran out of time” to legally fly us. They mentioned that they were about 2 minutes away from taking off. I understand the rules and safety but kinda wonder why they would have bothered boarding us in the first place? Had to go all the way back and de plane and then wait in a HUGE line to get a hotel (this is somewhere around 2:30am) finally got to hotel by Uber (no shuttle after 20min so gave up) and they ended up putting us all back on the same aircraft at 10am next morning so got about 2.5 hours sleep. They did give us. $250 credit, but it was a São Paulo Brazil flight out of Dulles. The flight and everything was fine.

United overall experience is great these days. Airport experience was very organized. Staff on flight were great. App and information as good as it gets.

United have really come back. Airport and boarding process is clear and good, app and information also very good

They charged a fee for 1st bag checked. Others in same party were free.

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

The movies offered were great. Staff were very pleasant and very efficient.

After a delay at the gate, C3, at Ohare on Sunday, I left my Blk ski coat on the bench at the gate, lost! Please review my lob claim, thx.

Very bad! They kept delaying my flight and wouldn’t do anything about it

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

It was just fine. I managed to make all my connection too sbut had trouble in Munich with no wheel chair and trouble trying to get help from the airport people to get to the other terminal for my flight. Finally a wonderful lady Amelia, helped me to make my flight connection Timon with zero time to spare.

Over 40 years ago my AC return flight was canceled, during this last summer the same thing happened. AC denied everything Canadian like paying for accommodations and basic necessities. So why would I ever want to fly AC again? This last flight my wife took the return flight had problems and left late, so I guess they are getting better. However I have no faith in this airline so I drove to this last destination! I'll never fly AC again!!!

Great check in process in LA and good service The check in process as well as at the gate is way better in the US versus canada 🇨🇦

Super experience. Earlier than schedule departure and arrival. Baggage handling was very good

Allow me to book extra bag check in as free though I packed in 1 luggage but that was 7 LBS overweight so make another bag to free check in.

I would like to get my money back. I flight was 4 hours late on the way to detroit, And same on my way back to Brussels they cancelled my flight and give me an other ticket and i had to wait 5 hours.

All attendents were very efficient, pleasant and happy. Everything went smoothly. The seats could have been wider. There could have been more free food instead of just one small bar.

My seat was one of those that couldn't recline, but the problem was that it was abnormally upright, so the headrest actually made the seat concave, which was uncomfortable and hard on my lower back. I had to ball my jacket up and use it as lumbar support. goodness I had it with me.

Boarding was so so after zone 3 was called all other zones went in

I liked a lot , the flight attendant so nice ,the seat very comfortable I enjoyed the flight , I will do it again with Air Canada,
