by the time they got to our row, they were out of some of the food options. games and movies were great but maybe more game options like tetris or pac man would be great

A few more inches of legroom is all i ask

Great as usual, some delays but well communicated and made up for in the air

Business class points redemption - good value for points paid, dubious value if out of your own pocket, domestic class business product okay for this length of flight. The flight left and arrived on time, crew were good, aircraft was a bit old and tired, but still miles ahead of their competitors in Virgin and Jetstar.

Airline running better than post Covid, proper boarding process now implemented, some aircraft feeling a bit old and tired, crew fine, online experience better.

We were upgraded and after just a short delay in attending to a safety check we were on our way. Would definately fly Qantas International on their Dreamliner again.

Five hour flight instead of four hours due to westerly headwinds which wasn’t the fault of Qantas !

I tried to check in online but was unable to do so. I stood in line for nearly two hours to check in. American Airlines was understaffed. When I finally got to the kiosk to check in, I was still unable to check in. No AA staff was available to help. Finally one of the airport security agents who was helping passengers became of lack of AA Staff told me: “I think the reason you can’t check in is that you are starting your name with an upper case letter when you write it. Just write it with all lower case letters.” That did allow me to check in. HOW COULD ANYONE POSSIBLY KNOW THAT IF THEY USE AN INITIAL UPPER CASE LETTER TO SPELL THEIR OWN NAME, AA WOULD NOT ALLOW THEM TO CHECK IN?????? Then I had to wait in line over half an hour again to drop off my baggage. Although I arrived at the airport 3 hours early, by the time I got to the gate, they had already started boarding.

One of the oldest most uncomfortable "lay down" seats I've ever experienced. Old plane and old seats that don't lay flat. The seat back does not even recline - at all. Instead the legrest awkwardly extends to fill the gap between a small cubby into which you must insert your feet/legs. I am 5' 11" and could not lay straight but had to tuck my knees. Ticket was also very expensive. Would not recommend flying business/first on Finair from Melbourne to Bangkok and will not do so again myself.

The wifi was out. Otherwise it was great flight. Richard, as CSM, was excellent.

Not sure how we end up with American Airlines instead of Qatar Airways. From Philadelphia to Qatar they boarded us then they asked us to unload. After 30 minutes later they board us again. The inside the plane it was burning hot and we were sweating like crazy. Crew members are absolute rude. The way they served the passengers were horrible. One of the crew members hit my knee with food cart and kept going. I was holding an ice pack for almost 2 hours. I am still with the pain.

Awful plane to Tashkent. Not even possible to sleep. In business class does not even recline fully

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.

It was ok, not much more can be said, as long as airlines/aircraft manufacturers insist on cramming in as many seats as possible....best of a bad situations, seats are simply too uncomfortable to sit in for more than a few hours. Lack of flexible headrests not a help on long overnight flights either.

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 only thing that could have been better, is that the food trays get left way to long after a meal. We had a snack 8 hrs into the trip, and they left us with the boxes and cups for way too long. It is not fun being trapped in your seat unnecessarily

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

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

I found the staff to not be very attentive at all. When paying for Business Class you expect a certain type of service and that was not found. They were almost rude even

United sent me a mileage plus number last year but that number is invalid so I can’t use it to check into flights or collect mileage. There is human to speak about the problem, only computers who keep asking me if I am using the correct email. It’s so frustrating and I cannot resolve it.

The attendant were friendly. I suggest you have a medical attendant on board every flight so that in case someone is sick , he/she will help them.

Boarded plane and then delayed 1.5 hours while on the plane

online check in was not available so i had to get to airport extra early. The flight was delayed and my luggage was lost. I had an argument with the person behind me who wanted to keep her bag on the floor and not allow my seat to recline on a 9hr plus flight. So overall, lots and lots of areas for improvement.

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

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.

We arrived 4 hours early and still almost missed the flight because they weren’t able to access one of the boarding tickets. They then sent hour bags late and we were all of our without clothing and eventually had to take an expensive cab back and forth to the airport as they wouldn’t deliver the bag which arrived late at night that day and we would have to wait until noon the began day (messing up a second day of plans). Also, all the food has dairy or pork. No vegan or even vegetarian option in the flight—even for purchase.

The flight was canceled 3 hours after original take off time

The comfort of the seats was great, the crew eased my child’s anxieties and the fact that I had full cans of my beverage choice was great.

3 hour weather delay followed by 1 hour (and counting) maintenance delay. UGH!

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.

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.
