I've traveled on Qatar to KTM couple of times. London to Doha or US to Doha service has been pretty good. It's from Doha to KTM where the service changes. Some of our nepali passengers were so rude. They got drunk, would not listen to the flight attendants, and kept on shouting. This one guy kept on standing up during landing. I was traveling with my 3-year old son and he got so scared. A drunk nepali guy kept on hassling my son with questions. It was awful. I'm not saying Qatar service is perfect but the passengers are not helping either.
