Everyone is so focused on the small end, but how many pilots does it to staff one 777? Maybe 20?
You're 20 pilots short on your staffing plan, do you park 2-3 RJs (having your 20 pilots fly at $200k+ a year) or do you find a way to defer the delivery of one 777 (and those 20 pilots then make $30k/yr) and have that route be flown by a revenue sharing joint venture, where those jobs are now at a foreign carrier?
Unfortunately the answer seems to be: both.
But, the top end is much harder to get a handle of, get an idea of how many jobs have been lost, and to protect against. It sure is scary.
