First of all I'm new to this thread and to BA. I'm pondering whether to use the current Diners Club (US) offer of a 50% bonus (i.e., 1 point = 1.5 miles) to BA Executive Club.
In reading the "sticky" I think some/all of the following links may be faulty. The first couple point to non-existent web pages (at least on my computer).
Thanks for the information. I'm still trying to decide whether this is a good place to deposit the miles.
