Yes, it's a promotion. I don't have the terms in front of me, but it was something like double miles for travel-related expenditures (other than at airlines) in the months of June, July, and August in excess of a specified monthly minimum. For me, the monthly minimum was $125.

I don't know whether it's appropriate to mention Visa promotions on an Amex board.... Wait, I know how to bring the topic back to Amex. I'm actually qualifying for a double miles promotion on a Visa that I've had for eight months, whereas I never qualfiy for promotions on an Amex that I've had for over twenty years!
