Friendly staff, surprisingly good premium economy seats allowing good sleep/ snooze opportunity and very good menu.

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.

Liked some flight attendants. 1 was rude I'll not say her name I don't want to get her jn trouble on my flight back to Dallas from Doha. Very rude to some races of people clearly. She needs a better attitude and bedside manners. Asking her questions and she responds "WHAT" twice rudely like I was bothering her and "is it going to be cranberry or mango juice with an attitude".

Qatar Airways did a very good job. Flights were slightly delayed with boarding but pilots made up time by arrival. The food was OK, no better or worse than other airlines. Although it would be nice to have three meals during 16 hours flight instead of two.

The space was tight, hardly any leg room and the crew surprisingly were busy and did not take the time to attend to passengers, felt rushed. There was a delay for check in since the systems were down the airport staffs were accommodating

Seat experience average as they use old 777 for must flights despite full load. Qr fares are higher than other airlines for same routes so they should at least upgrade the planes . Food is average and same dishes for months on most routes I travelled at least - the Arabian rice dish “Maqboos” on every flight for months - I am sure there are other food Arabian dishes ?? It’s become boring ! Crew is always good which makes up for these things but hey confirm us what we need

Overall good. Food choice in business class is a concern as same dishes on every flight for months. Crew is great and seats on this sector were fine . They need to have more variety in dining

Very unimpressed that I was dumped from the seat I had booked and paid for after check in. Apparently a family wanted to sit together, however as they all were adults I think they should have pre booked their seats like I did. I will be approaching Qatar for a refund. That and the dreadful state of the flooding toilets made me wonder how they managed to be voted the best airline. Not worth the money.

riding in first class, you don't expect every time you order your dinner or breakfast that the first thing the stewardess says is Let me see if we have any left. Also, the food selection was not great: 3 of 4 entrees had mushrooms and I dont eat mushrooms, the 4th item was 'let me see if we have any left' and this was within 30 mins of entering the flight! Same experience level, it didn't feel first class this round.

Was downgraded from business to economy due to a faulty seat in business class. However when I boarded the plane there were no less than 5 free business class seats. Will never fly Qatar Airways again

The overall flight experience between Doha and Kolkata was satisfactory. The staff onboard were notably engaged, responsive, and enthusiastic, providing a level of service that stood out, especially when compared to the less attentive crew on the earlier leg from Heathrow to Doha. Their eagerness to assist made the journey more pleasant. Additionally, the time spent at the Silver Lounge in Doha contributed positively to the experience. The lounge offered a comfortable and relaxing environment, with adequate amenities and attentive staff. Overall, both the flight and the lounge experience in Doha met expectations, making for a smooth and satisfactory travel experience.

Delayed my flights and no communication. We end up spending 6 hrs in Doha. No food or any concern from the airline. Terrible

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

Flight was cramped with every seat taken. The food was fine, nothing crazy to write home about. The plane felt dated and needing some TLC, the button for the window shade didn't work and there were no AC outlets to use. When communicating with staff all except one nice lady never seemed happy to help me almost like I was bothering them when asked for things like a glass of water or a snack. The flight was overall fine. It did what was needed which is get me from point A to point B. But it certainly was not special. I don't expect much in economy but I believe economy on a host of other airlines is more memorable and better experience.

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

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.

Old and out of date plane, it seem like every time I fly with united there’s and issue. We were delayed,

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!

I have long legs, my foot was out in the aisle and when a flight attendant came walking by and I didn't notice, instead of saying "excuse me" or anything like that, she kicked my foot. Extremely rude

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.

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!

My flight got delayed for almost 4hrs and then it thankfully went to only 2hrs. Then we were told that there were no space for carry on bags and I had to get it checked... well I counted at least 8 spaces that weren't used and I was one of the few left that actually had one. There was definitely enough space and either the crew can't count or just genuinely are so lazy they don't want to do their jobs correctly and make sure that there ACTUALLY is no space.

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.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.
