I regularly fly IB coded/operated flights GVA-MAD, and post to both my AA and BA accounts. The flights have never posted to either account in less than 10 days, so I imagine there is a 'batch' process that IB runs to issue credit to other OW carriers. Before I had my gold BA card, the IB flights would post about 1/2 the time. Now, I make sure the boarding pass is correct before I leave the counter. No more "it is in the computer, so it will be OK" story.

Bottom line, the miles/points will post in 7-14 days, or they never will...

Good Luck!
