I've heard bitter stories about transiting in New Delhi. I haven't experienced it myself so I'm not for sure how they treat the " gorkhalis " . I would recommend acquiring some indian currency just to be on the safe side.. .. .. .. I think it's insane that you have to check in again with your luggage... but I guess that's how it works out there.. only if we had transit systems in nepal.. we would have show 'em .. . they would only be allowed to take a flight after they have completed a full check- in a and special tour of hanuman dhokha.. ... but we are a peaceful country .. we would never do something like that ....
