The GTF Advantage features the most state-of-the-art hot section in the single-aisle market. It will deliver up to twice the time on wing compared to today's GTF engine, along with 4-8% more takeoff thrust, enabling longer range capability. GTF Advantage is fully intermixable and interchangeable with today's GTF engine model, simplifying operations for airlines like United that maintain combined fleets. Pratt & Whitney will transition its entire PW1100G-JM production line to the Advantage specification by 2028. 

Customers operating the current GTF engine model will have the opportunity to realize up to 90-95% of the GTF Advantage's durability benefits with the GTF Hot Section Plus (HS+) upgrade option for the PW1100G-JM engine, which will be available for incorporation during maintenance visits early next year.
