United ask pilots to take unpaid leave amid Boeing aircraft shipment delays

United Airlines is asking pilots to voluntarily take unpaid leave because of reduced flight capacity stemming from delayed shipments of Boeing aircraft. 

The delayed deliveries come after a slew of safety incidents involving United aircraft that have led the the Federal Aviation Administration to tighten its oversight of the airline. 

"We can confirm that due to the recent delays in Boeing deliveries, our forecasted block hours for 2024 have been reduced and we are offering our pilots voluntary programs for the month of May to reduce excess staffing," United said in a statement to CBS News.
