Perhaps.
However, why would a US Airline want to outsource to another country? We already have the lowest paid pilots in the world. Delta isn't going to outsource to Jazz or Cityline when they could just give flying to GoJet.
Not exactly.
For every British Airways, there three "Ryan Air's" low wages, lax labor laws and people clawing one another's eyes out to get there in order to get somewhere like... British Airways.
The math has already been done, trust me, you don't want it.
