Let's speculate here for a second
Supposed I have leased a 767 for oh, I dunno, 15 years, to do a small run between Chicago and Kansas City, and now I realized it was not a smart move.
Terminating the lease would cost me 49 milions$ and that is 48 milions over what I have.
What can I do with this flying white elephant?
a) assigned it to a better route? (What would that be? long international haul?)
b) not assign any route to it, and just let it be?
I don't know what my options really are.
