Our business model is based on providing scheduled regional airline service under code-share agreements (commercial agreements between airlines that, among other things, allow one airline to use another airline’s flight designator codes on its flights) with our major airline partners. In exchange for such services, our major airline partners pay us either fixed fees to operate the flight, referred to as “capacity purchase agreement,” or we receive a percentage of applicable passenger ticket revenues on the designated flights we operate, referred to as “prorate agreement.” Our success is principally centered on our ability to meet the needs of our major airline partners by providing a reliable and safe operation at attractive economics. From March 31, 2024, to March 31, 2025, we made changes to our fleet, including the addition of five new E175 aircraft and 17 partner-financed E175 aircraft.
