days 4567 in the CDG-IAD route
Seems like a lot more than that. In the weeks after the initial flight back in June, the flight (AFR028/AFR039) was a daily 388. Now since Jan 2, there have been only 4 times that the 388 was used, with the other 11 being 777 flights. And there doesn't seem to be any pattern to the 388 flights, with one each on a Wednesday, Thursday, Saturday, and Sunday.
This could also be a case of flight aware having the wrong equipment listed for a flight. But I haven't encountered that before.
Perhaps the best way to tell would be to wait until spring, a big travel time for tourists coming to DC.
