The most important innovation of the GE90 was that it used 22 carbon fiber composite fan blades, expertise first developed for the GE36. One among the foremost improvements for the engine had been its carbon fiber composite fan blades, which have been each lighter and stronger than conventional materials. They preferred that it could possibly be ferried Spin win with Free Slots one engine out, and could fly 'anyplace'- ETOPS (extend-vary twin-engine operations) hadn't begun then.

As enhancing engine reliability allowed ETOPS operations for nearly all routes, extra economical twinjets changed quadjets on many routes. Until November 2015, it accumulated more than eight million cycles and 50 million flight hours in 20 years. On June 27, 2016, a GE90-115B powering a Boeing 777-300ER, on Singapore Airlines Flight 368, acquired an engine oil warning throughout flight and returned to Singapore Changi Airport.
