They seem to be very inconsistent about the time taken to post the points. I have seen anywhere from 2 days to a week. The time that it took a week was right at the beginning of FTE, and it was a F fare, so I'm not sure if that had anything to do with it.
They are always posted and correct, though, and I've never had to contact CS. Unless if I needed the points right away (to redeem them) I probably wouldn't bother contacting them until 2 weeks had passed (after 2 weeks, it seem clear that something is wrong)
