Summary United Airlines' choice of Pratt & Whitney GTF engines for A321neos has led to operational setbacks. Disconnection in the supply chain has caused issues with multiple grounded aircraft due to engine problems. Despite supply chain and maintenance concerns, the PW1000 family engine offers efficiency and cost savings.
During last year's Paris Air Show , many were taken aback by United Airlines' surprise announcement to power its future A321neo family fleet, an order consisting of 70 A321neo and 50 A321XLR aircraft, with Pratt & Whitney GTF engines - the PW1000G. Given the American manufacturer's challenges at the time, many were surprised that United didn't choose to go with the competing CFM Leap-1A for its A321neo fleet. One year and many new issues later, the situation is even worse with the GTF engines.
Given that United's large fleet of Boeing 737 MAX aircraft is powered by CFM Leap engines, it is surprising that the carrier didn't choose an already familiar engine. Thus, all of the above begs the question: Why did United choose to power its future A321neo fleet with an engine seemingly against its interests?
