Traditional economy class. Not a full flight so spare seats. Food and drinks were good

10.0 ExcellentPeter, June 2025MEL - HKG

Traditional economy class. Not a full flight so spare seats. Food and drinks were good

Was bumped to a later flight because of inefficiency on part of the airline.

Inflight entertainment, poor that there are no headrest screens on aircraft used for an international flight.

The Emerits/Qantas flight was cancelled to Wellington. We need a refund. Had to buy another airline ticket. How do we get the refund. Still not in Wellington.

Delayed QF59 flight once again, Qantas doesn't fail in maintaining there delayed departures and arrivals. USB points do not work nor do the power point sockets on the plane, Qantas staff admitted that on the flight. Don't expect to your charge devices. Saving grace, was the ice cream. Bottom line, if you expect to fly to HND and make it on time avoid Qantas and if you're interested in ice cream - visit 7/11.

Pretty excellent. I don’t know what the pilot could have done better with the bumping ( there was a storm) nor what happened to my ears coming down into bendigo. It doesn’t happen coming down into Sydney just the return flight. I wonder why?

Touch screens were very difficult to use, generally being laggy and unresponsive- it was quite an art to get it to play the thing you wanted rather than some thing at random. Selection of films and Tv was good when touchscreen decided to finally respond.

Their aircraft are old and amenities lack way behind other international carriers leaving from BNE. Even in economy

Airport and crew experience was excellent. We had to queue for the runway - no one’s fault, but it did mean we were 30 minutes late leaving

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

Worse fight I ever take since I start flying , still have even made home , and crew abandon us half way home . No water no food and no even anyone to answer our questions

I’ve flown with Qatar multiple times and the service has always been great. Very professional, organized, the food is delicious and plentiful, tons of entertainment.

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".

I was unable to pre purchase sear upgrades or internet. Their online site is not user friendly and poor. I felt singled out in customs. Seats are very small even for a small person.

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 Qatar Airways staff pre-boarding and also on the flight from Dallas to Doha were incredibly mediocre and arrogant. Consider retraining these individuals Other flights were ok.

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.

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.

Smooth flight, especially take off and landing, and great crew on board. Really loved the stroopwaffles!

United out of SFO is having issues with catering so none of our meals were loaded on the plane and no offer of compensation for our tickets purchased was offered.

Food and flight attendents with positive dispositions and friendly behavior, more professional attitudes

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.

I’m impressed that we were on time in Sacramento after having a late departure in Newark and our made it. The staff was friendly and warm.

5.5 hour delay with no explanation on why, along with no proactive effort to reaccomodate me.

Flight was full, and would have preferred an aisle seat, but due to getting a late ticket ,the seat I had was adequate. The flight crew were very help full and hard working. Food and drink were excellent for the 11hr flight. Overall I was pleased with flight, and would recommend British Airways again.

More choices on menu. Seemed only thing offered was Scottish, and while that’s good for the Scot’s it doesn’t help the Americans who don’t like that food. And I really hate it when, during sleep time the attendants have a very loud conversation right over you. Lastly, I paid 5000 dollars for business class, and having to pay more to choose my seat early is really an insult. Seems greedy

Wonderful crew and early arrival to our destination. It was so nice to have free wifi access and movies too. Thank you!

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
