(KL miles awarded now seem hard to determine in advance. The ticket is on KL stock.)
Only use your KE number. Complete all travel - both the outbound and the return - and wait until all sectors have posted to your KE account.
Only then should you launch a missing mileage claim in Flying Blue for the "O" sectors in order to claim miles in Flying Blue for those.
Always let the miles post naturally where they go; once that process is complete, go and chase up the "missing" miles in your second/alternative programme
