God yes. Can you even imagine the problems at Delta? Twelve different type ratings and the most senior people flying the international widebodies that are now parked. Every guy they furlough off the bottom starts a domino effect in training, as that guy is replaced by someone no longer senior enough to hold his aircraft or seat, who is then replaced by someone no longer senior enough to hold his aircraft or seat, etc., etc, etc...

You could very easily generate requirements for a half dozen type rating trainings from a single furlough because no way is the seniority going to neatly line up with the aircraft still flying. And then the seat changes as junior captains default to FO in aircraft that they actually may never have flown before.

it isn’t like everybody has the same type rating and every aircraft is that type and each person is nearly interchangeable.
