Airlines cannot predict or plan around aircraft engine repair timelines, crippling fleet capacity planning

Airlines face unpredictable engine maintenance schedules that keep aircraft grounded longer than operational plans allow, forcing them to cut passenger routes and scramble capacity. Maintenance shops lack visibility into repair timelines, and carriers have no way to forecast when engines will return to service, making it impossible to schedule flights or guarantee aircraft availability. Current workarounds (shifting to cargo, reducing networks) are reactive band-aids that leave money on the table and frustrate customers.
