The industry went through a spectacularly difficult transition in the 25 years after deregulation.

The first half of that period was characterized by Chapter 7 and a lot of pilots on the street permanently

The second half was Chapter 11's and a lot of pilots on the street temporarily.

And all the FE airplanes got retired in that timeframe too.

The industry has changed/adapted/consolidated and the risks of MAJOR furloughs is low.

So take AA or DL ... it's not even close.
