Two pilots died in a runway accident that shut New York's LaGuardia Airport on Monday and U.S. President Donald Trump deployed armed immigration agents to help ease hours-long ​security lines at major airports strained by personnel shortages, although their impact was not immediately clear, Reuters reported. 

The crash between an Air Canada Express (AC.TO), opens new tabjet and a fire truck at LaGuardia injured dozens of passengers and led to hundreds of flight cancellations at the start of the working week in the latest disruption for airports and carriers that have been knocked off-kilter by a weeks-long budget standoff in Congress, according to Reuters.
