OK so looking at this (and the website) I can do something like:
Out: SAN-LAX-YVR-LON (stop) -FRA- BCN (dest)
Rtn: BCN-FRA-ATL (stop) -ORD-SAN
I am going to transfer points from Amex so can I call and check before I transfer the points or do I need the points in the account for the aeroplan agents to look at it?
