Make sure you keep your MH documents. I flew AMS-KUL in J and some regional Asian flights. Despite loading my FD number in at check-in, booking etc the miles did not appear. It took an e-mail, fax and letter to FD to get the miles credited (about three months). And this was a KLM codeshared MH flight with a ticket on 074 paper. On-lin retro claiming does not work on codeshare flights even if the ticket is issued on KLM stock with a KLM code.

But the miles came through in the end.

Also, are Malaysian domestic flights still exempted from earning KLM mileage? I took some very nice (cheap) F-class flights around Malaysia and found they accrued nothing on KLM. Presumably as most Malaysian domestic flights are government subsidised, MH is not prepared to buy the FD points as well.
