United Airlines' oldest plane: A look into their long-term fleet strategy

United Airlines, based in Chicago, Illinois, is recognized for having the largest commercial aircraft fleet globally. The airline operates over 1,000 aircraft, including a mix of Airbus and Boeing jets. Among these is the oldest aircraft in its fleet, a Boeing 767-300ER that first flew for United in 1991. This jet primarily serves routes within United's transatlantic network and to the Hawaiian Islands.

The airline has maintained an average fleet age of 15.9 years, making it one of the oldest on average worldwide. Despite this, United Airlines has plans to modernize its fleet through its "United Next" strategy by retiring older aircraft and introducing more fuel-efficient models.

Since 2021, United has ordered over 500 narrow-body jets and more than 150 widebody Boeing 787s. Additionally, they have decided to purchase 45 Airbus A350-900 jets to replace their older Boeing 777-200ERs. These new additions are expected to improve operational efficiency and enhance passenger experience with features like Bluetooth connectivity and power outlets at every seat.
