sahjayog,

I am also looking to travel to Nepal this winter in Dec. I am getting my tickets from our local travel agent in dallas--Sky Pass Travels; they have a Nepali agent working especially for tickets to Nepal and he got me a good deal on my tickets in October, last year. So check out with him; you can google Sky Pass Travels in Dallas to get their contact info.

Good Luck. BTW, where are you flying from????
