Boarding was effortless, the food was outstanding, the seats in Premium Economy were extremely comfortable, and the staff and crew were excellent.

Very good overall. However, your choices of free movies was limited and there was no music Channel???

This was the worst flight I’ve been on. Getting on the plane where is was 30 degrees outside was hotter on board cabin must’ve been 33 degrees. This is a health hazard. They cannot be doing this to save on fuel. People could die from this!!. Fans and a/c was, off entertainment was off. Poor excuse given. Crew made the excuse that the system didn’t have enough power. They basically were operating on one engine to save on jet fuel till 3 hours later on cruising altitude and they then started the second engine. And finally the cabin was cooled. On a 7hour red eye flight this made it so uncomfortable and impossible to sleep.

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+.

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

I disliked the fact that they forced people to put up their seats during meal service

Amazing! Was put on the earlier flight and I requested for an aisle seat and was given it. Thanks Qantas!

Boarding was terrible - the ground staff member Fredeya at lax was more military than customer service, have never encountered a customer service representative as rude as her. Apart from that all other staff were wonderful and the flight was good.

I travelled first class from LAX to MEL and it was a series of disasters which I put down to lax staff who dont care and a suck it attitude to customers - its all lip service and no delivery. The flight was delayed due to aircraft refuellers putting on 300,000 litres of fuel on a 380Q1. I entered via the first class bridge loaded my bags in the overhead locker. the lady in the next isle in first class also had hers in there as she wasn't allocated a locker over her seat. The attendant asked would I like a champagne - I said yes please. he promptly delivered a empty glass and the glass left on the desk. Then he ignored me for 20 minutes. When i asked him is he out of champagne he gave me the usual rubbish I was distracted. There are four staff and 15 first class passengers - give me a break. the glass stayed there on takeoff and then was still there 9 hours into the flight. When I arrived to my seat I told him I had eaten and wouldn't be eating on the flight - it was 10.30pm. Yet he comes by later 4am ( I happen to be awake) and says are you eating with us? I asked for the bed to be made up - they put a 3 inch 7cm mattress on the chair but as usual the break in the chair - the mattress sinks into it - so I had to move it around so I didnt get my back sunk in the V - Im 187cm tall. The cabinet next to 1K is for staff bags and the toilet is next door. I tried to avoid this seat but couldn't change - in to the flight 8 hours and the cabin rest change over kicks in - this attendant is shining his torch in my eyes taking out and returning his bag. Then the toilet starts flushing and forget trying to get to sleep. Yet no-one else needed torch! 11 hours into the 15.5 hour flight I ask for breakfast - I order two poached eggs, bacon on multigrain toast, tomatos and mushrooms. I get no bacon or toast and have to order it and the eggs are cold. Then I order a coffee which is so badly spilled - and not by air turbulence she brings back a serviette and replaces the first one rather than providing a clean dry saucer! First class in Qantas is a joke as the staff just don't get the meaning of prompt service and attention to detail. I will fly business class rather than first on Qantas as its better value for money but I have been very impressed with United First Polaris and given I fly internationally every month this is going to be my choice.

The business-class pajamas, though thin, and the mattress pad were much appreciated. This plane had adjustable air vents and enough room in the forward galley for me to stretch between meals.

Fine not above and beyond as I had a connection that was delayed due to maintenance

HORRIBLE, my initial flight was cancelled, they made me pay $200 extra dollars and that got cancelled as well! After 6 cancellations I decided to get a refund because I needed to get home to my babies. Out of $1000+ dollars they offered me only $40 in refund! Totally unacceptable! The flight that they cancelled I was able to fly it on another airline. I had to spend $400 on one way tickets just to get home! I’m still getting the runaround.

Flight was delayed. De-icing took a while. When we landed had to wait for another plane to vacate our gate. Just an overall bad experience.

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

Our flight was understandably diverted to a small regional airport in Laramie, Wyoming due to weather conditions, which I fully recognize and appreciate. However, the low rating stems from the experience that followed: passengers remained on board for over an hour without the option to deplane and stretch, despite the aircraft being stationary. Although the pilot opened the cabin door, only he was permitted to exit. Meanwhile, passengers grew increasingly uncomfortable as warm summer air entered the cabin through the open door, and being in the second row meant we were impacted immediately. While the flight attendants made efforts to keep everyone at ease, I believe allowing passengers to deplane briefly, given the extended delay, would have significantly improved the overall experience.

Overall a very poor experience - booked premium economy tickets but due to last minute flight delays , all my itinery went for a toss and had to fly economy class with no access to lounge or any compensation by united airlines to make up for the flight delays . i had expected better experience than that from united.

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

My flight was delayed for a whole day, so I lost a day of my vacation.

Onboarding - it would be great to see on the screen what group they were boarding. It was very confusing on who was boarding (even though they called it out) they were not clear and the space to board was strange.

Older plane. Food was really bad, almost not worth the effort. Huge difference with European based airlines.

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

Good crew and flight was on time. It’s a small plane with limited overhead luggage space. They said the overhead space was full and I had to check my bag. There was still space when I got on. Waiting for my checked luggage added 30 minutes to my trip. Not the end of the world but also not great.

Trip delayed for 2 hours because of rain. We boarded and have to get down the flight and reboard again.

No enough space plus only allowing one laggage instead of two like other airlines.

Qatar airways ,boarding arrangements at Hamid international airport could been better

Two flight changes before the scheduled flight. On the day of the flight, the flight was delayed, which caused the connecting flight to be missed. Then, I was directed to another airport (CUN) and traveled to Tulum. American gave a $12 voucher for lunch. The least expensive item on the menu at a Mexican restaurant was $9.99. Driving to Tulum was a bad auto crash, and traffic was delayed two-plus hours. The bottom line is that we should have been at the hotel at noon, but it ended up at 11:30 PM.

Miami lounges were overcrowded and we were unable to get in. We only had a short time. But the banks are too tight in all American hubs

DO NOT BOOK THROUGH AMERICAN AIRLINES IF YOU HAVE ANY ADDITIONAL NEEDS. Great flight, crew etc. it wasn’t full so had space to stretch out Only downside was there was no GF option for my partner. We booked through American and it was a Qantas flight so despite contacting both airlines to confirm, she didn’t have a gluten free meal for the 16 hour flight (nor the flight in the other direction). The flight attendants did their best to accommodate but it was not super substantial.

Overall boarding and debarking is a joke. I dont even bring luggage anymore on trips because you can never allow them to be place then in the overhead bin or you have to pay or you check them which is even worse having to wait for your luggage on the tarmac.

First time flying internationally with AA and probably my last. Not military friendly at all. Didn't allow free checked bag for military family members (dependents) on orders like other airlines. We were charged $100 for baggage weight overage (5 lbs!)even though we had military orders allowing us extra.. Didn’t allow military members to board early. Inefficient and long wait time to board. Seats are smaller and more uncomfortable than other airlines.. no drink service for over 7 hrs of flight! After initial meal was served, the crew never offered a snack or drinks until the breakfast's was served 1 1/2 hrs before landing. Overall expensive and poor experience for the entire flight.
