dreamer is right...one of my friends who recently went home for Dashain via Delhi confirmed that you do not have to even leave the terminal...also mentioned he had no problems whatsoever in Delhi...and he saved a bundle too.. his total cost to delhi (roundtrip ticket bought at travelocity) was 1020, and he spent an additional 120 for the roundtrip to ktm-- I think he probably saved about 300.00
