Looks like the way you do it to setup an account for "Cello YourLastName".

(I get the sense that very few people in the world do this, and their stories have spread like a good urban legend.)

If you or I decide to take "CheapGuitar YourLastName" on a mileage run hoping to hit a juicy promo twice in half the time, we'd probably get the schpiel about inanimate objects - and CheapGuitar would get tossed into the belly of the plane.
