Pratt does NOT have bad reliability!! I've flown on an worked on Pratt engines for 45 years. GE bought their exclusivity with Boeing for the 777 and 747 but we'll see about the newer models as PW develops the GTF technology. If it was all that? Then the USAF didn't think so as their new tanker the KC-46 is equipped with Pratt PW4062's which I KNOW to be a reliable engine and it has been since it replaced the JT9D
Go check the IFSD stats I've mentioned: CF6-80A2 vs PW4000, RB211-535 vs PW2037 and get back to us.
On the 767 in ETOPS service the PW4000 IFSD rate is almost twice that of the CF6-80C2. I believe that the KC-46 got the PW engine for political reasons, like the F-35.
