United Airlines Requests Pilots to Take Unpaid Leave Amid Boeing Delays

United Airlines is asking its pilots to take time off in May due to delays in receiving new Boeing planes, leading to a shortage of flight hours. The airline expects similar requests throughout the summer and possibly into the fall. The shortage primarily consists of Boeing 737 Max planes, including a new, larger model, and the FAA's increased scrutiny of Boeing is likely to further delay the certification of the Max 10. United is considering options to replace orders for the Max 10, and CEO Scott Kirby has been vocal about the problems at Boeing, seeking a meeting with Boeing directors. Boeing's CEO is set to step down at the end of the year as part of a leadership shakeup at the company.
