Bucking, while there's no way mainline labor COSTS could match that of Go Jets, one question is to ask is could that be negated by a REVENUE increase to DELTA. To outsource that flying, Delta must relinquish some of the revenue to another operator that would have normally gone to them in order for that operator to make their own profit.

Depending on the circumstances, it might be possible for mainlines to recapture SOME flying like that and break even as opposed to outsourcing.
