A new study finds that boarding an airplane back-to-front doubles the risk of exposure to COVID-19 for passengers compared to random boarding. While back-to-front boarding limited exposure of seated passengers to those walking by them, it increased proximity between passengers sitting close together. Results showed the new method doubled the risk of exposure compared with random boarding. What's more, back-to-front increased the risk by 50 percent compared to the typical process of zone boarding prior to the pandemic. This gathering defeats the social distancing purpose of back-to-front boarding.'
