Thanks for the heads-up.

I had already booked a MCS cross-country fare for later this month (for biz, so no cost to me to pay extra for the guarantee, though I'm sure I would have been upgraded anyway). I guess I will call the Gold line to see if they can give me the double-points on the base fare so I don't have to cancel and re-book (though maybe that's what they'll do on their end).

I'm also curious how this double-points bonus will interact with the 100% bonus I already get from Gold (i.e., will I end up with 3x or 4x points -- guessing 3x).
