BANKE, May 1: Mohammad Aayatulla Rahaman operates a travel agency near Rajha Airport of Nepalgunj. About six months ago, he was preparing to send 15 passengers to Humla by a Tara Air chartered plane. As his business was just getting started, he planned to give his clients a  proper farewell with  garlands and khada, the traditional ceremonial scarf. However, when the day for the flight arrived, his company could not fly the clients from Nepalgunj  even though they had already paid the airline.
