On a 787, even at Delta rates, the pilots are basically free. A pilot costs a passenger about a dollar an hour.
If ALPA wins, it means that NAI has to hire a bunch of union pilots from the US/EU to run their operation. The US regionals have 20K pilots alone ready to work there. ALPA won't stop them, NAI is coming. The question is how do we deal with them once they are here?
