As an LA native, my bet is that the Mexico flying is going to be profitable for Delta. And operationally speaking, I would guess that it could be one of the better performing hubs for ASA.
With the disappearance of Aerocalifornia, Baja is ready to be served.
So are the smaller cities that Delta has announced it's going to serve.
Unfortunately, my only concern would be that if SKYWEST baggage handleres handle ASA flights, expect Delays.
Too bad ASA isn't hiring right now.....
