For your information, the carousels at Munich, Germany (MUC) go counterclockwise. And the airport code for Dulles in Virginia, USA is IAD, not DIA. I can verify that the motion is ccw there too.
You’re welcome.

Many thanks for letting us know about Munich. And for correcting the airport code for Dulles and confirming that its a counterclockwise airport.
