You've read it? Maybe you can answer this then,

The AIP is purported to have hard snapbacks and concessions are temporary. The thinking is that these concessions are required because of the downturn in revenue caused by the pandemic.

My observation is that humanity has done a miserable job so far in predicting the end of the pandemic, yet our pilot negotiating committee has agreed to an end date? How do they know?

Since you're in the know, is it possible that snapbacks are tied to UAL cash reserves so that if United is at risk of violated covenants (free cash) and is headed to bankruptcy that we enter BK with our "real" contract?
