I was denied lounge facility at airport. Explanation was not satisfactory.

6.0 GoodAnonymous, Jan 2025TRV - DOH

I was denied lounge facility at airport. Explanation was not satisfactory.

My experience with Qatar airway was very unsatisfactory. They lost my child’s stroller and I was told they found it and will send it to the hotel which was a lie. I had to go back to the airport baggage claim and pick up myself after trying to contact them many times!. There was a lack professional and communication. I am very disappointed in Qatar airway and will not be recommending them to friends and family nor will I be flying with them in the future.

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.

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.

Overall experience was OK. Seats were truly uncomfortable for such a long flight. Food quality was mediocre at best. The staff was great though!

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

It was good no problems made it on time for the next flight overseas!

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

Should have had business class line in immigration. Food quality suboptimal

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

The staff were wonderful but the seats weren't very comfortable for a bigger guy like me.

The flight take time was changed 23 times. The system kept sending messages it will be earlier at 4am and eventually the flight was at 9am I didn’t sleep all night because of that

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.

Bad. Flight was very uncomfortable with narrow and shallow seats, very little food and water. I will not fly etihad again.

Needs better seat for business class. My seat was falling apart. Also no WiFi on that flight

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.

Good. The food was very bad. Except for the chicken rice, rest of the dish went to trash.

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