That doesn't make any sense! If they are licensed to work on A340, B747 and B777 (and these aircraft fly all over the world and not to a certain region), still they would only fly to their own division?
A340 goes to JFK and BKO (Bamako). Still, the crew belonging to Division Afrique would only go to BKO whilst the crew belonging to Division Amerique to JFK, wouldn't they?
