Keep in mind that at present there is a BA transfer promotion going on.
If British Airways didn't know about it, what would you expect them to do about it?
If you borrow the 3-hole punch from the office overnight and take it back in the morning, have you broken the company rules?
If you get to the subway and the only turnstile is out of order, are you committing a crime by jumping over it?
Is this is the worst sin you ever commit, you are more than welcome to marry my daughter, if I ever have one.
