Have no idea if it's true or urban legend, but....
I heard that the MOD tried to make Virgin give it the air miles from personnel travelling on the Heathrow-Dulles trooper. Virgin refused, apparently saying that air-miles were nothing to do with who paid for the ticket but purely a gift to the traveller.
In addition, has anyone ever actually tried to use BA air miles for business? A colleague tried to use his to upgrade on our last trip to the US and was told that air miles couldn't be used with the HMG bookings.
