American Blames United’s ‘Reckless Scheduling’ for O’Hare Woes

American Airlines Group Inc. is blaming its competitor, United Airlines Holdings Inc., for overscheduling at Chicago O’Hare International Airport that has resulted in US regulators moving to reduce summer flights at the busy hub.

“Without intervention, United’s reckless scheduling will lead to challenging conditions at ORD this summer: long taxi times, extensive tarmac delays, missed customer connections, disrupted crew sequences and cascading disruptions across the system,” American Airlines executives said in a letter sent to Chicago employees on Tuesday.
