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.

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.

Planes was old - business class seats looked like they were installed in the 80s

Our baggage didn’t arrive with us on the plane. Need I say more?

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

I have taken this flight many times. It is ALWAYS late. Every time there is significant delay (1-3 hours) before boarding. It’s very consistent. Even after boarding the expected landing time was delayed twice. The seats are very narrow and cramped. Food is barely editable. Considering an economy ticket often costs about $2,000 it’s one of the worst services ever.

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

headphone jack didnt work for the first flight and not much variety

Delays took 2hours and thirty minutes making me miss my connecting flight and make me sit in the Chicago airport for 9 hours

All male crew was just too woke for me. I felt like a sardine. I will never take a window seat or the rearmost seat again. I booked early and did not pay for seat selection and that was a mistake. The security at IAH was atrocious. I was violated and radiated as I was in a hurry to connect to my other flight. I may have lost items under the seat in front of me that I couldn't see nor bend over to look.

Great. Food going from Australia to the US was better than other way around, but still needs improvement in terms of quality and quantity!!!

It’s been awhile since I have traveled on United. I, along with my family who were on the flight noted how smoothly everything went . Boarding, flight crew and service was excellent.

Change cabin crew assisting business class. Not taking care, ignoring requests and calls. Never had such an experience in business class.

Average. Newark is a United Hub, yet a flight that is early somehow ends up getting late to the gate. Newark ATC needs help badly.

First class felt like economy, seats were horrible, food was horrible, staff inattentive

Boarding was easy. RDU gates can get crowded, be prepared to be patient. Flight was smooth, with excellent service. Pilots really provided a lot of visibility into flight details. Plane and seats were clean and serviceable. TY!

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

The flight was delayed leaving Miami. When we arrived in Charlotte, we were unable to park at our scheduled gate. We had to wait another 30-45 minutes before we could park at a different gate. All in all, we were delayed by almost two hours arriving in Charlotte.

Same as before being upgraded to business class made it perfect

Flight delayed on both ends - have a gate ready at DCA, don't make us sit for 30min after being late to take off as well.

The seats were crammed and the guy in front of me wouldn't stop reclining. If AA is cramming extra rows in, they need to take away the reclining in coach. My knees were smashed for 4 1/2 hours and I was very close to confronting the passenger in front of me.

This flight didn’t happen because AA agents didn’t let us board the flight

I had two wonderful flights - very relaxing and got me there early!

We got upgraded for this flight. But the particular bright spot was the flight attendant in our cabin. She was attentive but not intrusive. She interacted in a personal way with each passenger and gave a great service. Thank you!

Only thing that I liked it that I got to my destination safely, otherwise American Airlines stinks.

No overhead space so all carryons were checked. No internet.

The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.
