Interesting, thanks. The 25 is a sequence number, it is not related to March 25th. The BN promo code sequence has been in use for a long time. I can't recall seeing a promo code beginning with FGB before now, even though it is up to serial #15. Looking back through the promo offer history shows some interesting offers that I'd not heard about...but then again for many months I was unable to follow this forum other than on a very sporadic basis.

The curious can view the BN025 promo offer and the FGB15 promo offer if they are logged in to MySouthwest; just be aware that the "Register" button won't work if your RR# is not on the target list for the given offer.
