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.

Boarding procedures are very tiring. We have to clear security twice for our connecting flights from Doha. Also every time we board flights we have to show boarding passes 5-6 times.

Overall good but staff in the place looked extremely tired after 8hrs in 14 hrs journey and then service was cut short and response time for calls increased in later part of flight. Food was ok not astonishing

Very bad. We booked 8 months in advance for 2 people but couldn’t get seats together. Food was so bad I couldn’t even eat.

The plane from Dublin to Doha was quite comfortable. I was in economy and the seats and rows were very tight. The man in front of me reclined his seat and it made my screen incredibly close to my face and I wasn’t able to take my tray down and my knees were pressed against the seat. I had to ask three times for him to pull his seat up but in his defence he hadn’t even reclined it far, the rows were just too close. I had a pain in my side by the end of the flight from the chairs which were quite worn and not very padded or supportive. It was a significantly inferior plane to the plane from Doha to Sydney and vice versa.

In spite of placing requests for vegetarian food, I didn’t get it because they ran out of stock. According to crew, only fixed number of vegetarian orders will be carried. Typically, they should have checked and served those who had specifically requested. I was one of those to get the food last.

You're like a poor man's Emirates Airlines. The Asian vegetarian food was awful. The entertainment selection was very limited and not contemporary at all. The seats were cramped. There was no plug for charging my phone (I refuse to plug into a USB port - A security risk). The plane itself was aged.

Vistara i bought a biz class fare but a few days before vistara always changes my biz class flight to economy .. happened to me 4 times .. seated could be wider .. boarding could be more organized .. crew did their best but not enough resources all in all very poor experience Qatar Delhi .. only complain .. no clear signage to lounge for transferring pax .. its a Delhi shot coming.. no feeling of exclusivity for biz/ 1st class pax.. but everything else was much better .. once i boarded Qatar .. i loved it Qatar to Washington .. only complain i boarding .. too crowded .. no separate area for biz/1st class should hav completely separate area for upper class.. security is stifling pax comfort by the gate ..but everything else was great

I really did like the food and beverage and crew was really good!

Seats were not comfortable and touch free remote wasn’t working.

The flight was canceled. Got rebooked to Chicago and when we arrived our luggage where to there. They were going to our original destination the day after. They would not deliver them to our house. We had to go pick them up.

One of the best flying experiences I’ve ever had.

The overall ambiance was good. Seating ain the last row not so pleasant.

Liked the excellent United crew, the food selection, the comfortable cabin and the excellent movie and tv shows selection. The interface on the screen is also excellent and gives the option to let the crew know to wake you up for meals, or not. I disliked the onboarding experience at the Brussels airport. The process is convoluted and was not explained to any passengers. I also don't understand why thee is an additional security screening when getting off the plane from Africa, when there was none when getting off the plane from the US.

They rerouted flight to LAX. Offered nothing but a 5 hr drive to SBP. No compensation. No regards to our healthy and safety.

Boarding was quick and efficient. My screen didn’t come on and everyone else had theirs working so a little bummer but it was a short flight!

The flight was clean and on time, the crew were all very nice and we got the seats we booked. Plenty of food and beverages. The seats are too close so it’s very difficult to try and sleep comfortably.

Due to a cancelled flight the day before this flight only had 44 people. Best flight ever on international route. Food getting better. Can United provide fruit ex apples and bananas for snacks? Crew fantastic.

Entertainment system did not function screen kept trying to reset. There was no beverages handed out luckily it was short flight.

The whole ordeal was a fiasco, the flight was delayed which made me miss my next flight and I had to spend the night in Munich. The german airlines customer service was very, very, very rude and total jerks. I do not recommend using Lufthansa to anyone.

Flight was delayed three hours waiting for the flight crew, even though the plane was at the gate for the scheduled departure

Late boarding to clean plane from previous flight; initial boarding announcement not loud enough; fantastic cabin attendant front of plane

It was less than what is expected for a business class ticket I thought that the staff actively ignored me because I either looked Indian or Hispanic to them and I guess I did not deserve their attention. The food which included a beef entree was not available so not enough food was ordered for number of seats available. I will say experience in Greenwich lounge was very good and the staff there at the airport were very nice. May be your crew needs to learn about racial equity so that everyone gets either the same aweful treatment or hopefully the best treatment which is what we expect I recommend you take a flight with Singapore airlines that I have taken and the crew remember your last names and use it to address each person, food never finishes if you are at the back of business class and crew anticipate your need even before you articulate. Same price and 100 times better service than American Airlines

American Airlines canceled the flight twice and was unable to facilitate a change of city for us after our travel plans became affected. We lost alot of money due to this and it seems like the airline was trying their best not to facilitate this. Mind you, I am a very loyal member.

For an over three hour long flight one pack of cookies was not enough.

Gate change was a little tough but it was a good flight otherwise

American always delays flight so it stressful getting the next connection

I had first class itinerary, yet they put me boarding group 5 from FNT to ORD! I spoke with the gate agent though, and she let me board in Group 1 like I should have been assigned. Would've liked water on that flight. I'm glad that I asked about food on the flight from ORD to DALLAS. If I fly United from ORD to any city in Texas, they always offer a hot meal and regardless if it is a time in between meal times. The excuse was that it was not dinner time yet. It was almost 6pm?? And the flight was over 2 hours. There were some healthy snack options at least, but fresh snacks like apples or something would be nice. At least offer cheese plates or similar. Please bring seatback screens like United is doing. The flight attendant in first class was wonderful.

Flight was a delayed a few minutes but nothing crazy, everything went extremely well

The flight attendants were rude. People sitting next to me agreed as well. Wifi wasn't to bad... it went into and out a few times.

It was a domestic flight so the food was not included. But we had not even a little snack and by the end of the flight they were coming around serving water.

On the flight back from SFO to Vancouver ..the crew was less than professional. They completely missed asking if I wanted a drink (and I was awake at all times) and I had to walk to the back of the plane to ask for a cup of water to take with my medication. Also, there was a charge for ear adapters for the movie screen which were given out free on the flight from Vancouver to SFO. The flight from Vancouver to SFO had pleasant crew members. What a difference in the flight back.

I got hurt and needed a wheelchair. They were excellent. I also appreciated the fact that they kept me informed thru out the whole trip regarding boarding, gate changes and luggage info.

Everything is very good, No need to be changed. Thank you

Terrible. We waited for over an hour to get our bags. After a 14 hour flight is was extremely frustrating

It was very bad travelling with air canada the people working at check in bagages was very bad person any way I pay to much many to get good flights but it’s not

Rouge airbus seat pitch is the worst I’ve ever experienced. 6’7” and couldn’t properly fit my legs in.

very disappointing there's no food service on an almost 7 hour long flight

It was a very pleasant trip from A to Z.
