I just returned from a trip to SIN. All of the flights on CO metal have posted.

On March 29th I flew NW 19 from NRT to SIN. The ticket was on the CO codeshare CO 5019.

There's an entry in my OP on line statement of the date and flight, but no miles posted.

How long does it generally take for NW to notify CO?

Thanks in advance for your assistance.
