The American/Hollywood movies in the entertainment system lack english subtitles, they tend to have only arabic subtitles. Coupled with the low quality airplane earphones and cabin noise, it sometimes is difficult to follow the movie dialogues.

Seats very small and unable to pre purchase internet or seat upgrades

I recently travelled in Business Class with Qatar Airways, and overall, it was a pleasant experience. The cabin crew stood out for their kindness and professionalism, making the journey truly comfortable. The food exceeded expectations and was exceptional in both quality and presentation. The boarding staff was courteous, though I would like to mention that the staff member responsible for checking tickets during boarding could benefit from additional training to be more welcoming. A warm and hospitable approach would enhance the passenger experience significantly. However, one aspect of the journey was particularly frustrating. The in-flight entertainment system was disappointing, as the headphones provided did not work at all due to a loose connection. This significantly impacted the experience, especially since the flight also lacked Wi-Fi service. Addressing these issues would greatly enhance the overall travel experience. Lastly, I would suggest implementing a section-wise boarding process to streamline the boarding experience and minimise potential challenges. I appreciate the efforts Qatar Airways puts into delivering high-quality service and hope to see these improvements implemented in the future.

The food is not good and also if you ask crew to bring something they say ok I will bring but you will never get it. Please they should listen good to passengers

Qatar Airways in-flight first/business class service is superior to any US airline; excellent meals are served on short haul flights such as between DXB and DOH.

Boston to Doha was great but Doha to Dhaka was the worst experience.

The rows of seats in economy class are seriously close to one another making eating and resting just about impossible - there is hardly any legroom. Anyone larger than average size would have an incredibly uncomfortable flight. I had to basically share my seat with the lady passenger next to me as she was too big to fit into her allotted seat.

Do I need to repeat my complaints about my lost carry on bag?

As gold member there is no priority checkin. Meaning you either have to board with your zone or last with business class pax. As economy pax all the baggage bays are filled by the time you arrive

they give hard time at checking, they not allow computer bag or purse

I was charged for my daughters bag when I am supposed to receive two free checked bags with my United Explorer card.

The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.

I needed to make changes to my flights. When I called customer service, they assisted me with care professionalism.

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

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

Seats were comfortable. It’s was so cold and very uncomfortable. I paid 2000 miles for wifi service that was choppy the whole flight. Would like to be reimbursed for my miles Food was so disappointing. Three cold and terrible meals for $3000 round trip. This needs to be better.

Very good - being handicap it was very hard for me in a center aisle bulkhead seat that Zi was assigned think it was 29-G as I had a hard time opening the entertainment screen and tray table. 30-G would have maid it easier. I was assign 29-G as it was the only handicap seat without being charged even though I was handicap (disability)

Great. Food going from Australia to the US was better than other way around, but still needs improvement in terms of quality and quantity!!!

Fight was delayed an hour due to operational issues ,then further delayed due to ground control for a total of about 1.30 hours. Salad was completely frozen and flatware was so cold you could barely handle it. Crew was friendly and professional and the flight was smooth. The aircraft was clean and well-serviced.

I completely missed my flight because the first leg was longer than planned. I had to sleep overnight in the airport because no accommodation was provided and then sent to Trinidad in the morning with an anticipated 7 hour layover before my flight to Georgetown which was now with Caribbean Airlines. I tried twice with customer service to see if they could put me on an earlier flight which had seats available but was told it wasn’t possible.

Mechanical delay and no compensation. Missed connection as a result of their delay. Mediocre performance and service. Horrible airline currently with horrible culture.

Several delays. Next flight was worse. Did not arrive home until 2am PT

We missed our flight. The boarding pass had the wrong gate and by the time we received the text from Kayak, our flight was already gone. I’ll never use Kayak again and will go direct to the airlines in the future.

Uncomfortable seats and flight attendant was rude as she insisted on waking up my husband to ask him if he wanted a drink. When he said that he was sleeping, she replied “without an attitude “. He was seated at 8c

Very friendly and efficient and smooth boarding. We were even way early arriving at my destination. Thank you.

Flight was delayed taking off over 2 hours. Original plane was taken out of service and replaced. They didn’t tell us they were replacing plane until after original takeoff time had past. No power on new plane to charge devices. When eventually landing at destination no gate was available waited 1 hour for new gate. No Americans finest hour.

The flight was quick and to the point. The crew just did their job w/o excessive talking and everything was just perfect.

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.

Everything was great except it became so hot on the plane I couldn’t sleep on my red eye flight. It didn’t really cool down till we started descending.

Same as before being upgraded to business class made it perfect
