The problem is Nepali travel agencies (in Nepal) have hard time confirming a ticket; I don't know if it is the outdated Amadeus software (?) they use or something else, but none of the 3-4 travel agencies I contacted have been able to tell me the ticket has been confirmed despite my giving pretty good time range (i.e of about 2 weeks starting end of July to 2nd week of August). Although, I've not been pleased with the price, when I do try online, I get the instant response.
