Questions like this can generally be answered by consulting the T&Cs of the offer and/or existing FT threads, as is evidenced in the answers above. (The T&Cs of the offer can be found on the United website. @:-)) 6-8 weeks after the end of the offer (i.e., 6-8 weeks after June 15) is correct. Don't expect them to post any sooner than 8 weeks (i.e., mid-August).

Interestingly, last year the double EQMs posted right about the END of the time promised in the T&Cs, which was several weeks later than a lot of people hoped, and therefore there was a lengthy thread with a lot of whining and screaming about "why haven't they posted yet" etc. Really unbelievable. I hope we don't get another stupid thread like that this year.
