Anybody know how a typical 9-10 hour us-europe flight is run. It seems to me like KL, BA, and AF would make very efficient use of their planes if they just fly IAH-EUROPE and turn around. They could cover the daily flight with one plane. Anybody know if this is what they actually do. If anybody flies a particular flight all the time, is it always one of two planes.

I know it seems stupid, but sometimes I'll plan "my airline". I need to know what kind of restrictions I have to work with.
