Nepal has been sent into another political whirlwind today and there may be intermittent (or worse) street protests, etc. 
H1N1 Flu has appeared causing the WHO to consider raising it's alert to State 6/Pandemic level.  This can make travel through Chinese and other airports difficult  and some travelers have encountered weeklong delays.

These things may cause apprehension in some travelers and some trips may be cancelled.  I am hoping for better days soon.  Lynne
