There was not enough food for everybody. Some dishes were missing.

8.0 ExcellentAgnieszka, Oct 2024NBO - DOH
Read more Qatar Airways reviews

There was not enough food for everybody. Some dishes were missing.

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.

Moved seats, didn't accommodate requests to change seats even though other seats were available.

Being a QR Platinum member traveling in business class, I expected the staff to be more courteous. Unfortunately, the lady staff was rude attending business class 1K side.

Staff was very friendly. There is no on board entertainment, but it’s such a short flight that it doesn’t matter. We also got a meal which was nice and unexpected due to the length of the flight.

Flight was fine overall. What you would expect from economy seats. I did appreciate the amenities (eyemask, earplugs, small toothbrush and toothpaste, thin socks).

Qatar airways from Doha to guangzhau was excellent big bird Boeing 777 more room and smoothly flight, I Love it

Not good. Expected a lot more as far as excellence.

It was a long flight but overall a good one. The one thing that I would comment on is that there is a real problem with disposable plastic products when it comes to the meal service. It would be great for Qatar Airways to find ways to make its meal service more circular and reduce the immense amount of waste.

I staff or crew they were very friendly and humbly, they done theirs service very well, I appreciate them and thank you to the company or Qatar 🇶🇦 Government for providing as good service in their flight ,once again, thank you 😊 🙏 😀 😉 👍

The seat was like there is no leg space....there were no proper option for food in the airline. It seemed like the airline was at brink of bankruptcy. The crew was helpful except for a few.

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

The flight was delayed which cause me to miss my connecting flight in AbuDhsbi airport.

Long way to improve. Toilets not working. Bad handling when flight was canceled

The business class experience is fantastic. The crew were polite but often unavailable even when I tried to call them! I even found myself bringing my used dishes and cutlery up to the crew because no one had come to collect it after over an hour.

Online was good boarding also but a child was crying all the way with no intervention from crew member.

1st of all on February 27th Abu Dhabi to Delhi flight the seat wasn't comfortable at all, coming back the Lounge at Abu Dhabi didn't have anything. Than the Food in the flight

Overall mediocre experience. Check in was good. They're were discriminatory. They were not attentive, food choices were not vegetarian friendly. The food served was frozen.

1st time with. Etihad Airways and it was amazing from check in to crew. Great flight.

The staff was very nice and polite but it was very very hot and no ways to have some fresh air. It would be nice to have more time to sleep since it was a night flight
