Florence Brown, the airport's communications director, said while stay-at-home orders in states across the country have put a halt to most travel, PHL still has a role.
And there's a steady stream of cargo planes — some carrying needed COVID-19 response supplies for greater Philadelphia.
Brown says the airport has never seen passenger counts like it’s been recording the past few weeks.
"Our reduction in air travel is looking at about 80% to 90% down year over year, and that's what we're monitoring by week," Brown said. "But, again, we’re encouraged by that news, because it means that this country is trying to keep itself safe."
In the meantime, Brown said the airport’s complement of nearly 800 employees remains on the job, with about one-third working from home.
