I often have stays outside US, as a result the bill is not in USD. Points are calculated on the USD amount so there's a currency conversion involved. There used to be a point when I did not really check the number of points awarded and just checked if all stays posted. Since last year I'm paying more attention and I noticed that each and every time the number of points I receive is below the number of points I would expect based on the exchange rate I use (google).

It always involves small amounts butt adding everything up I may have missed a few 1000 points by now. This weekend I had another stay and yet again there's a 5pct difference.

Have others similar experiences? Has anybody ever complained about this?
