While reading one of the reports of flight diversion, I started thinking about how airlines manage aftermath of the diversion especially for long haul transatlantic flights.
Many of the reports say airlines provides a replacement plane. Replacement plane flies to the diversion airport, load up the passengers and continue.
If the original flight is full, what happens to original crew? Working with the assumption that new flight has new flight/cabin crew and there is not enough place for all.
If the airport is at significant distance where the replacement comes from or still has to fly significant distance, it's possible that replacement flight crew might run out of flying time.
Do they provide multiple sets of crews - one to fly to diversion and one to fly to actual destination.
