Just wondering if anyone knows how often/when miles for CO flights post to a FD account? Is it X no. of days later or is it batch posted every few weeks or whatever? I took some CO flights lately and the outbound posted within a week. More than a week since the inbound and nothing.

FWIW, some Hilton stays posted nearly a month after the stays (all on consequetive days) so it appears Hilton stays are batch posted near the beginning of every month with a cutoff date of around 25th day of the month previous. An Avis rental took a week to post.
