Yes, I read the last part, but it still sounds like a Yank applying a U.S.-centric interpretation of the word "scheme" to a post where it's used it in the U.K. sense (which doesn't have the same sinister implications).

To the OP:

1. Welcome to FT!

2. The additional information requested in the first reply would help. It's hard to collect enough miles for this without flying, unless you own a business and can put all its purchases on a mileage-earning credit card or some such. So, knowing what other flying you expect is important.
