> The manufactures of aircraft engines are not doing the service on those engines. I would be hard pressed to think of an airline that gets GE and its ilk to service the engines. Many airlines and fleet operators of all sizes "lease thrust." The airline signs a contract for X amount of thrust for Y planes, writes a check....and RR, GE, CFM, etc configure the engine's control unit to deliver that amount of thrust (which can be anything up to the engine's rating), and handle everything necessary to assure that the engines go vroom when they're supposed to. That means maintenance/repairs, handling parts/supplies logistics, live monitoring via satellite telemetry and predictive analysis. On your next flight one of the engines could be showing signs of future failure or accelerated wear and the parts will be on their way to the shop, time booked on the mechanics schedules, and airline alerted to the plane coming out of service for X amount of time to accommodate the repair, before the plane is even half-way to its destination. I don't know why you're speaking so authoritatively on a subject you don't know the first thing about.
