All was good, the only thing was it didn't run on time.

Great meal. Best seats ever! They need to teach other airlines how to do that.

Crew were pleasant, happy to be there and were a joy to be around. Entire operation was professional, well thought out and ran like a Swiss clock.

United flight from SFO to PDX was cancelled. I will ask for a refund. Had to book on Alaska

They announced food service but then never came around. We also couldn’t land so kept trying to get to runway and then had to come up and go around happened like 3 times and cause the child next to me to start throwing up

The recline on the seat in front of me came back so that I was staring at the top of the man’s head in front of me the whole trip. He refused to bring his seat back up twice every time he was instructed to do so and only relented when he had a tray of good in front of him. And then right back in my lap!!! Horrible man!! I complained to the staff multiple times, but no one would address the issue. Otherwise, it would have been a perfect flight.

There was a snafu with confirming seats at check which left us in limbo for the second leg of our trip. I believe the ANZ app is not well integrated with the systems at the terminal resulting in this disconcerting error.

Flight was canceled due to technical issue shortly before the check-in counters opened. Passengers were rebooked on a flight three days later. Request to be accommodated on Air Tahiti Nui could not be processed. Customer service sorted out the refund after calling and being put on hold for almost an hour.

Carring crew, nice ambiance of the cabin, comfortable beds, good food well served. We liked everything.

The pilot tried to make up for lost time due to delays that were out of her control. She communicated the issues openly and clearly and made every effort to do what she could to alleviate issues.

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

It was a good experience except when boarding a female flight attendant did not go out of her way to assist my teenage daughters in finding space for their carry-ons after their compartments were full.

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Big plane, long flight, absolutely no leg room and basically non existent air! I am 5”4’ and always travel Main Cabin, I was miserable on this plane and could barely move when we arrived in Cabo due to the cramped leg area!

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

The pilots were good. Disappointing when planes don't have electrical ports

I liked the piloting of the aircraft. Very disappointed about lack of electrical ports. Also, although a short flight. there was enough time to hand out snacks to comfort + seats as was done for first class.

Initial flight was cancelled so moved to an alternative flight. As a result, stuck in a middle seat. Flight then place in holding pattern prior to landing resulting in a very late trip home.

There was nothing I didn’t like, prices a little lower would help

Flight delay was informed at the last minute. Food quality is not up to Qantas standard I was unable to book an online boarding pass on any of my 6 flights.

Rescheduled after ticket purchased and issued, not 2 or 3 times and not a fourth but by 5 times, by Qantas, that's right, 5 changes! Forcing an overnight stay in Chile and need for visa. Qantas can no longer provide basic services as a national or international service provider. Professionalism is extinct and the provider needs to be mentored and educated in perfecting who to operate as an airline. Qantas is the spirit of Australian dissatisfaction.

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

The crew were amazing - A great job. They made me feel special and valued.

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.

The flight met my expectations. It left and landed on time

My bag didn’t make it but otherwise it was a great experience.

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.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

All flights were on time and boarding was issue free

Terrible! The plane was old and you are required to connect your own device to their Wi-Fi rather than have entertainment options in the back of the seat in front of you. The Wi-Fi went out during the flight and there was only one plug for the devices every two seats. Three out of five surrounding my family did not work. The seats and spaces under them were so small I could not fit my backpack, which I’ve always brought on flights and fit before no problem. The crew were unpleasant and patronizing.

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Food was terrible Not many options Stewards dont care Delay

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

Again, multiple delays and I eventually just canceled and drove!

Great crew. Very comfortable business seats with nice bedding. Good food. We were delayed to let late passengers on the flight, but otherwise great experience.

Great crew. We were delayed so that late passengers could get on the flight. Love the bedding in business class. Good food. Great experience.

The CX617 from HK to BKK was delayed more than 1.5 hours.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

I was in business class. There was an excellent headset. But half an hour before arrival they collected them! The rest of the trip I had to use a cheap earphone. There must be a better way to protect the headphones.

All four American Airlines flights I took in last seven days were delayed. Caused me loads of problems, missed meetings, loss of time and money.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money
