For years, airlines ordering the Boeing 787 Dreamliner have had a choice to make. Do they go with Rolls-Royce’s Trent 1000, or General Electric’s GEnx? In theory, both engines promised efficiency, lower emissions, and cutting-edge technology. But in recent years, that balance has started to shift.

And in a market where engine choice can shape an airline’s profitability for decades, that’s a very big deal.
