The number of people traveling by plane has dropped by about 96% amid the coronavirus pandemic, according to multiple metrics.
The drop in passengers and orders across much of the country to stay at home have caused airlines to cut 71% of their capacity, according to Airlines for America, an industry group that represents carriers such as American, Delta, Southwest and United.
Only about one in every 10 seats on the US domestic planes that do fly are occupied, the group says.
The passenger airlines are also currently awaiting their first payments from a $25 billion federal fund meant to help them meet payroll. They are also awaiting details on how to apply for another $25 billion in loans.
Several US regional airlines have been forced to suspend operations or close because of the dramatic drop in bookings.
The Federal Aviation Administration says employees at 38 of its air traffic control facilities have tested positive for the virus, prompting altered operations and cleanings. Most recently, it said employees in Orlando and Newark tested positive.
