We (DAL) have "general vicinity," which means you can't be in another city on short-call. The unwritten call-out time is 2 hours.
NYC and LAX are special cases, one only has to be within "2 hours" of one of those airports.
Correct. The widebody orders will be smaller and more frequent going forward.
As far as buying Boeing goes, they are a big backer of the EXIM bank, and have no qualms selling 100's of widebody jets to subsidized foreign competitors with tax-payer-funded loans.
At this point it's just business.
