Vail, fuhgetabout it, no CX published fares out of Vail.
The rest I can't make sense of.
thread title is
ATL?-xxx-HKG-KTM two awards
but then text is:
I recently tried to make a booking using miles from SE Asia to the Middle East zone, specifically Nepal.
and:
The route from HKG to KTM was one fare and then another one to HKG
If by SOME chance OP meant flying from N.America -> Nepal (as the thread title might imply), transatlantic routing only.
