According to the Transportation Security Administration, more people are choosing to travel on commercial airplanes now than they have over the past seven months. That’s despite a recent spike in COVID-19 cases around the country. So, how safe is it to be on an airplane, or at an airport, right now? We get some answers to those questions, as the holiday season gets underway. Our guests are Dan Pippenger, chief operating officer for the Port of Portland, which operates the Portland International Airport and Richard Corsi, an indoor air expert and dean of the College of Engineering and Computer Science at Portland State University.
