Can United TravelBank be used to fly to Asia ?
I'm looking to fly from the West coast to Vietnam again (SFO-SGN).
I have $570 in United TravelBank .
There are several flights on StarAlliance for this destination, for example on Eva Air, but all with 1 stop (no nonstop US / Vietnam flights exist).
Strangely, those Eva Air flights can't even be booked for cash on United.com, let alone with miles or Travelbank.
Is there any way to use my Travelbank for this trip, or am I SOL ?
