The first flight with one of these engines took place on 22 February 2007, using a Boeing 747-100, fitted with one GEnx engine in the number 2 (inboard left hand side) position. By fall 2019, General Electric was offering the GEnx-2B, developed for the 747-8, for the revised 767-XF variant based on the 767-400ER, but needed enough volume to ...
On November 22, 2013, Boeing issued an advisory to airlines using General Electric GEnx engines on 787 and 747-8 aircraft to avoid flying near high-level thunderstorms due to an increased risk of icing on the engines.
