The TSA announced Monday morning that for the first time since March 16, the U.S. had more than a million air passengers a day. Historically, airports saw between 2 and 2.5 million passengers coming through each day. Numbers plummeted in April to below 100,000 and stayed in the low 100,000s in May. The aviation industry got hopeful in June as the numbers slowly ticked back up to half a million, but as more waves of coronavirus outbreaks hit over the summer, numbers remained around half a million, occasionally ticking up on holiday weekends.
