In this April 1, 2020, file photo, several dozen mothballed Delta Air Lines jets are parked at Kansas City International Airport in Kansas City, Mo. The number of Americans getting on airplanes has sunk to a level not seen in more than 60 years as people shelter in their homes to avoid catching or spreading the new coronavirus. The Transportation Security Administration screened fewer than 100,000 people on Tuesday, April 7, a drop of 95% from a year ago. (AP Photo/Charlie Riedel, File)
