📉 Gestair Fleet Remains Unchanged, Utilization Falls 40.1%
Gestair had 28 active aircraft in each of two consecutive 30-day windows, but flight activity declined significantly, with the contraction concentrated in per-aircraft utilization. Avi-Go data show that, based on unique tail numbers with complete flight records during each period, the operator completed 499 flights totaling 1,017.21 flight hours from July 6 to August 4, 2026, averaging 36.33 hours per tail number. From August 5 to September 3, 2026, the figures fell to 303 flights, 609.18 hours, and 21.76 hours, respectively. Average flight time per tail number decreased by 14.57 hours, or 40.1%. With the number of active tail numbers unchanged, the shift during this window primarily reflects lower mission frequency and shorter flight duration among existing aircraft rather than an adjustment in the size of the active fleet.
Impact: The reduction of 196 flights and 408.03 total flight hours will directly affect the pace at which Gestair aircraft reach hourly maintenance thresholds and how crew assignments are scheduled. Meanwhile, all 28 aircraft remain active, meaning that parking, management, and fixed maintenance resources must still cover the entire active fleet.
Recommendation: Gestair could break down the average of 21.76 hours from August 5 to September 3, 2026, by tail number, prioritize identifying aircraft significantly below this level, and adjust crew rotations, scheduled maintenance, and parking arrangements for the next 30 days accordingly. It will also be worth monitoring whether the active fleet can remain at 28 aircraft and whether flight hours per tail number recover from the level recorded during this window.
