So I've read that you can only redeem once a month. But I can't find anything about whether the FLIGHTS have to be at least once a month...

My question: If I redeem a 1000mi award in Aug, and a 2,500mi award in Sept.... but I fly twice in Oct, would I get those award miles? Or just the 1000mi? Or even both on the first leg?

I have not experience with e-rewards redemptions, so any help is appreciated!
