A recent report from the CDC emphasizes the significant role of empty middle seats in airplanes for minimizing COVID-19 exposure among passengers. As travel resumes with increasing vaccination rates, it’s essential to understand how certain safety measures can effectively reduce virus transmission in enclosed environments like aircraft cabins.
The CDC, in collaboration with researchers from Kansas State University, analyzed data from 2017 regarding potential exposure to airborne viruses in various seating configurations on airplanes. Their findings suggest that leaving middle seats unoccupied can decrease the risk of contracting COVID-19 by an impressive 23% to 57% compared to fully booked flights. The data relied on models that simulated the dispersal of bacterial aerosols, reflecting how a virus like COVID-19 might spread similarly.
The research indicated that when middle seats were vacant, the risk of exposure was notably diminished. For instance, if a passenger was sitting two seats away from an infectious individual, their exposure risk dropped by 23%. However, when middle seats were unoccupied across three rows, the risk of exposure decreased to 57%. The study concluded that removing potential infectious passengers from middle seats significantly enhances safety for remaining travelers.
It’s important to note that this data focuses on exposure risk rather than actual transmission rates, and does not take into account additional safety practices like vaccinations or mask-wearing, which are crucial in further reducing the risk of infection.
Despite these findings, many airlines are moving away from the practice of keeping middle seats empty. As reported by Bloomberg, Delta Airlines, the last U.S. carrier upholding this guideline, plans to end the measure starting May 1. This decision appears to be driven by the airline industry’s need to recover from substantial financial losses incurred during the pandemic, totaling around $35 billion in 2020 alone. Unfortunately, the potential for more space and reduced anxiety about virus transmission while flying may soon be a thing of the past.
