In fact, you will be WAY better paying fixed AS miles for last-minute flights, given that VX->AS at 1->1.3.
Especially if you redeem for F. This is probably one of the best arbitrage opportunities out there (read: I suspect AS is being super-generous either by accident or intentionally, but it won't last forever, because like most arbitrage opportunities, they go away once FT and blog readers descend on it like vultures).
