I did not read all the other guesses, so if I'm repeating anyone sorry.

If history is close if you are in the bottom 45% spend the next couple of months preparing financially.

However, it is very likely 30% of all the big 4 will be furloughed. Hope not.
At UAL that would mean somewhere near 3,500 pilots. It will not happen overnight (of course it actually could with all the surprises this crisis has given us) but over probably 6 - 8 months and during that time be evaluated a few times.
