srodr, from what others have posted in the threads re: bonuses, it looks like all the Amex bonuses are combinable -- and retroactive, if I'm not mistaken. So you can buy the ticket now, and you'll get all the Amex bonuses you register for, including BLM1.

thecortex, according to the fine print, tickets must be purchased between 4/1 and 6/30. I got the BLM1 offer in the mail, so here are the relevant conditions, for reference (I skipped over the usual legalese):

• This offer is valid only on flights operated by Continental Airlines, Continental Express, Continental Micronesia or Continental-ticketed flights on Virgin Atlantic or Air France. To qualify for this offer, all flights must be round-trip and flown from 4/1/01 through 6/30/01. [...] Tickets must be purchased from 4/1/01 through 6/30/01 with Blue from American Express. [...] Double OnePass miles will be calculated on the actual miles flown.
