Flying return between Kathmandu and Bharatput. Nominally a 15-20 minute flight. Trip to Bharatpur was delayed 6 hours. Apparently it's usually at least 2 hours late. The front area of the terminal was more comfortable, barely, but the Nhudda agents at the front counter had no information about the delay or time to get more information, so we'd go through security, check the status from the gate agent, then go back out of security to the front of the terminal, then... for five hours.Then we sat on the bus for a while, then the plane (which actually was air-conditioned from an outside unit to a reasonable temperature). Once in the air, the prop plane flew as expected.
