Staff shortages across the industry are affecting availability
American Airlines is trimming 31,000 flights out of its November schedule. According to both CNN and aviation analytics company Cirium, that accounts for 16% of the airlines’ total schedule. American couched the move as being "in line with our approach to network and schedule planning throughout the year."
Breaking down Cirium’s data, the two routes suffering the most cancellations are American’s Boston to Philadelphia route and Chicago O'Hare to Dallas-Fort Worth.
