Usually bonus miles of the kind you have in mind show in your account exactly 24 hours after you have
completely forgotten about them. Then you start wondering why you got the 1000 miles (or whatever) until you do a search in FT, find your several-months-old posting and you remember again! The only miles that take longer to be credited are those from the duty-free shops in AMS. Either they
never show, or it takes several years...
