VA upgrade with miles policy
I have 50-odd thousand VA flying club miles and want to use them to upgrade a return from LHR-LAX from economy to upper. If I search for just reward flights the system shows very little availability (1 or 2 seats!) in the entire month I want to travel (March 2014).
If however I buy an M class ticket, will I be guaranteed to be able to use my points to upgrade (I know this is an upgradeable fare class) assuming upper is not already full, straight after I make the booking or is the availability of miles only ticket purchase seats the same as miles upgrade ticket seats? I'm out of the UK at the moment so not able to call them.
Any help appreciated.
