United Airlines Pilots Asked to Take Unpaid Leave Due to Boeing's Delayed Deliveries

United Airlines is asking pilots to take unpaid time off next month due to delayed aircraft deliveries from Boeing, impacting the airline's growth plans. The request comes after United had to pause pilot hiring this spring because of the late arrivals from Boeing. The airline was contracted to receive a certain number of Boeing 737 Max planes this year, but now expects fewer deliveries due to production issues. Boeing's CEO announced a leadership shake-up last week, but the company did not immediately comment on the situation.
