Thanks Chipledhunga, Monking bird and Zen Travel.  How about e-ticket ?  Chipledhunga, did you use e-ticket when you travelled to Nepal recently.  I have seen on Zen Travels webside that Dragon air can not process e-ticket at Kathmandu as of Jan 2008.  Is it still true or they already started to use e-ticket? Thanks all again for the  help/info.
