...is there a remote chance that the unionization within the big operators is responsible for NHV being able to "get more flying done with their crews"?
I don't work in the NS but have many friends working there.
No offense, but to me it is understandable how you could get more work done than working only 13 days/month, 4-5 hours/day (at the airport, not flying) plus vacation and sick leave.
Running for cover...
