Delta Sees a $15 Billion Engine-Repair Bonanza in Airbus Jet Deal

Delta Air Lines Inc.’s new order for Airbus SE jets shows that it’s sometimes the side dish, not the main entree, that helps land a blockbuster deal.

In announcing a purchase of 100 planes, Delta also said it would become a major maintenance provider for the Pratt & Whitney engines powering the aircraft. That opens up a new revenue stream for the airline’s TechOps unit, which serves other airlines in addition to Delta.
