5X points for airfare -how/when do they post?
Hey, new with Amex Platinum. Bought airfare a week or so ago. I assumed 4X points would post right away and then the 1X points for the purchase would post after billing cycle closes. Similar to many Amex offers with double points. So, how does this work? If the points don't post right away will it be easy to identify down the road that this airfare purchase got 5X points?
