Four Corners Aviation (ULA) has ceased Cessna Citation charter operations following the retirement of its sole Citation XLS from its Part 135-certified fleet, ch-aviation research reveals.
N619FK (msn 560-5777), a 16.7-year-old aircraft configured for up to eight passengers, was last active under Four Corners Aviation’s 'ULA' code on December 31, 2024, flying between Dallas/Fort Worth and Dallas Addison, where it was based. Originally registered in Sweden, it was exported to the United States in 2022 and joined Four Corners Aviation’s fleet in 2023. It is currently not listed as Part 135-certified.
Following this retirement, Four Corners Aviation's charter fleet consists of a single 12.3-year-old Learjet 45XR, also configured for up to eight passengers. The company retired seven other jets in 2024, including another Citation, its only Citation Excel.
