Turkish Airlines implements flight cancellations and seasonal route suspensions due to a combination of severe meteorological disruptions—such as heavy winter snowstorms and low-visibility fog affecting its primary hub operations in Istanbul—and strategic network restructurings. Broad network adjustments are driven by soaring global jet fuel costs, regional geopolitical instabilities, and soft passenger demand on select international thin routes, prompting the carrier to optimize fleet utilization and reallocate capacity toward higher-performing destinations.
