Great food and good entertainment options for the long flight.

Loved the food and beverages available, spacious economy class, excellent entertainment

Very good overall. Highly recommend for all flying to Australia

We had bulkhead seats in a A380 in the upper deck in seats 31 D and E. Storage was very limited other than in overhead bin - which is not within reach when in seat. Yet paying same price as others in premium economy who have a lot more storage within arm’s reach. Seems very unfair.

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+.

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

Terrible. 6 hour delay with no explanations and only 15 dollars in food credits. A disaster. I'll just leave it at that.

It was so hot on the plane mixed with being quite turbulent and a rough landing. We all felt very nauseous for hours afterwards. Crew were lovely though.

After flying Quantas (Prem Econ - SYD-SFO) which was Spectacular, we boarded AA flight SFO/PHL.. Prem Econ was NOT available on this flight so we were stuck in Econ - even though we paid $2600 EACH/ONE WAY for this ticket. I even had to BUY extra legroom seats - this AT LEAST should have been included on the AA flight. There were no screens in seatbacks, forcing passengers to use phones for entertainment. No water bottles were provided - only cups of water. The Quantas flight was FAR superior to the AA flight - even though we purchased Prem Econ for the FULL trip....

Ease of boarding. Staff were friendly and helpful. Food was good. In flight entertainment great.

Uncomfortable plastic seats even in premium economy. No free wifi. Even paid wifi was spotty to nonexistent. Bad food. Much worse than economy on foreign carriers like Qantas.

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

Everything went well except the turbulence what no one have a control of but pilot and crew handled very good!

Good flight. However, when booked flight with United, assumed the layover included by United in San Francisco of 1 hr and 40 minutes was sufficient . Not so and would recommend at least 2 hours or more. Needed to go through US immigration (very long lineups), then pick up bags, take all the way to another terminal, running because we did not have sufficient time. We made the flight because they held the door for us but luggage didn’t follow.

I still prefer Delta, but Delta doesn’t fly to State College PA.

Flight departed owing to SFO TSA delays as well as incoming flight running late I know these delays are commonplace but when you’re flying long haul international the least that could be done is priority being given to customers in this situation I raced to the gate the plane was still there but NO UNITED AIRLINES STAFF in the surrounding area could seemingly provide effective support This coloured my view of flying with UA The actual flights were good

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

Nothing bad to say about the actual crew or airline. It was nice to have a complimentary FULL can of soda, as well as a snack. Blankets and earbuds were also provided at no cost for this red eye flight. I especially appreciated the free WiFi and movie selection with the Bluetooth option. It helped the flight pass more quickly. No matter who you fly, boarding and disembarking are always SUCH a pain. As I mentioned, this is on the passengers and not the crew!!

Flight attendants rude and impolite… flight delayed by almost 5 hours.

Ok so apparently the new policy on United Airlines is that customers in the main cabin should NEVER be served more than once and besides picking up trash there should NEVER be another interaction with the customer for any reason.

When we checked in at the Siem Reap Airport in Cambodia, we were only given three boarding passes and told that we would have to check in with American when we arrived in Boston. This was a source of stress for us. After we landed in Boston, we had a long passage from Terminal E to Terminal B (American Airline ticketing counter). Because the electronic ticketing kiosks for check-in would not recognize our Confirmation Code, we had to wait for an hour in a long line where only two AA reps were taking care of Special Services passengers. In many years of both business and recreational travel, I have never had this experience. I would expect more from AA being in partnership with other airlines to do a better job with this.

It was very good. It was a long flight and being a tight with little leg room.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

Not sure how we end up with American Airlines instead of Qatar Airways. From Philadelphia to Qatar they boarded us then they asked us to unload. After 30 minutes later they board us again. The inside the plane it was burning hot and we were sweating like crazy. Crew members are absolute rude. The way they served the passengers were horrible. One of the crew members hit my knee with food cart and kept going. I was holding an ice pack for almost 2 hours. I am still with the pain.

I felt that when I was rerouted it should have been to business class.

Seating is terrible, having seats so crammed is unacceptable for a 15-hour journey. I cannot stress enough how uncomfortable it is to sit in such an aircraft. Leg space is roomier in a domestic aircraft. I have not experienced this kind of crammy seating in domestic flights either in the US or other international airlines overseas.

It was a really long flight from Doha to Philadelphia and it was overall a good one. The one area that I would comment on is that there is a lot of single-use plastic and disposables in the meal service for American Airlines. It would be great to see more circular options in the meal service to reduce the amount of waste.

I found it weird that the quality of the flight different from Australia to Doha than the Doha to Berlin leg. The quality of the toiletries pack (was in a box from Australia) and then a proper bag from Doha. The biggest variation was the inflight entertainment, which had a significantly shorter amount of content compared to the Doha flight. My QSuite seat was also broken and did not recline all the way flat. Wasn’t the best and I wouldn’t be happy if I’d paid cash for the flight.

The crew was great and the food and liquor offerings were good. Seats were a bit cramped. Flight arrived early at destination. That's a plus.
