Keeping middle seats open on plane could reduce passengers’ exposure to the virus that causes Covid-19 by greater than half, in response to a brand new study revealed Wednesday.

Researchers from the Centers for Disease Control and Prevention and the Kansas State University present in laboratory modeling that passengers’ exposure to SARS-CoV-2, which causes Covid-19, on wide-body and narrow-body planes could be lowered between 23% and 57% if airways depart middle seats open — even when they don’t seem to be carrying masks.

The study comes after airways have spent a lot of the final yr touting stepped-up cleansing procedures and onboard filtration to calm vacationers frightened about flying throughout the pandemic. Travel demand has since rebounded considerably as extra of the general public is vaccinated towards Covid-19.

U.S. airways together with JetBlue Airways and Southwest Airlines capped capability on board their planes earlier within the pandemic however have since done away with the policy, citing hospital-grade filtration on board and different security measures as limiting the chance of exposure on board. Delta Air Lines plans to cease blocking middle seats next month, the final U.S. airline to make the change. It paused its capability caps throughout Easter weekend, although, throughout a staffing scarcity that contributed to dozens of flight cancellations.

The researchers’ study didn’t look at mask-wearing on flights, which turned an airline and federal authorities coverage throughout the pandemic.

However, they cited a New Zealand case study that stated “some virus aerosol is emitted from an infectious masked passenger, such that distancing could still be useful.”

They used a surrogate virus to face in for airborne SARS-CoV-2.
