anyone know when you hit the lifetime million miles, does anything happen?
Nope, as it's actually not that hard to hit if you're a frequent flyer. I know I don't fly nearly as regularly as some on here, and I clock up almost quarter of a million miles a year. You can, however, cash in your 1 million airmiles for a trip to Necker Island. I believe a flight in to space for 2 million.
But don't expect Richard Branson to walk on the plane and personally replace your gold card with an engraved solid platinum replacement when you hit 1 million.
