And don't need the miles so badly that you've got to bold your entire post and worry about the miles posting over the weekend.

My Chase OnePass miles posted several days after the statement closed. I was happy with that, since as you acknowledge, the T&Cs give Chase/CO six to eight weeks to get the miles posted. There are a number of transactions that have to happen. First, a purchase has to occur and be posted to your account. Not a big deal, but it might take a day or so to clear fully. Then, Chase has to inform CO you've complied with the terms of the offer. And then, CO has to post the miles.

None of that has to be instantaneous. Or, if you're lucky, it could happen in lock step progression in the matter of hours. I wouldn't make plans around "instantaneous."
