Simple isn't it

Thanks for helping me understand that. So the real difference is that MLH is listed as a domestic flight from Paris and BSL a international flight. Do the planes park right next to each other? Odd. Would someone earn credit for the MLH-BSL flight? According to the flight shown it is listed as a flight.
