Are you all carefully monitoring your accounts after flights & hotel stays? I find it astonishing how often you get an incorrect amount of points or no points at all.
I haven't kept any statistics, just off the top of my head I would say that around 50% of the time I have to file a claim.
That's why I sometimes think that those hotels and airlines should give bonus points each time they give you a run for your points or miles.

This month so far:
Hilton & Marriott posted correctly
Accor: got points for the stay, no points for the extras (food). Was solved in a matter of days
Iberia: points for 3 flights out of 4
AA (credited my wife's Iberia flights to AA as that is her main account) : 1 flight out of 4 posted incorrectly. Showed up as Economy while we flew Biz
