The CDC Says Blocking Middle Seats Really Could Reduce In-Flight Exposure to COVID-19

The Centers for Disease Control and Prevention (CDC) has waded into the debate on whether blocking middle seats on flights could reduce the risk of catching COVID-19, saying in a new study that the risk of exposure could tumble by between 23 and 57 percent if social distancing was maintained.

The study comes just two weeks before Delta Air Lines becomes the last U.S. carrier to abandon its middle seat blocking policy as domestic travel demand rebounds and more and more planes take to the skies without a spare seat in sight.

Conducted in partnership with Kansas State University, the CDC study concluded that leaving vacant middle seats to increase physical distancing could “provide additional reductions in SARS-CoV-2 exposure risk”. The study does, however, come with some important caveats.

The CDC admitted that the laboratory experiments for this study were conducted before the current pandemic so it didn’t take into account the routine and mandatory wearing of face masks to help reduce exposure.

Nor did it take into account the effect of vaccines in keeping people safe – instead, the study was just looking at the risk of exposure and not the risk of actual transmission. The study also said that the experiments were conducted in a higher humidity environment – which could have an impact on how far a virus droplet can travel.

Using different modelling approaches, the researchers found there was a 23 percent reduction to the risk of exposure when applied to a single passenger who was sat just two seats away from an infected passenger compared to sitting in the middle seat.

The exposure reduction dropped to as much as 57 percent when researchers looked at a three-row section that contained a mix of SARS-CoV-2 sources and other passengers.

Delta Air Lines said it took the decision to lift its middle seat block because of the success of the mass vaccination drive. The Atlanta-based airline also pointed to another study that concluded the risk of onboard transmission of COVID-19 on a full plane when everyone wears a face mask is just one in a million.

Other studies, however, have concluded that exposure to COVID-19 and inflight transmission could be increased when passengers are sat in close proximity to one another – even if they have taken a pre-departure test and been cleared to fly.

An earlier study published last summer concluded that blocking middle seats could reduce the risk of inflight transmission by nearly half. The airline industry dismisses those concerns, saying multiple layers of protection – including mask-wearing – are a good enough alternative to blocking middle seats.

Last year, United’s chief communications officer described middle seat blocking policies as a “PR strategy”.

  • But, But…Hepa filters and downflow air handling. All this is just guesswork at this point. The CDC seems clueless. They will allow people to travel for many hours in sealed metal tubes at 35,000 feet but won’t allow people to sail on more socially distant ships with large outdoor spaces, masked and 100% vaccinated crew and passengers.

    • The COVID 19 mess is all Trump’s fault for not following the CDC and “the science.” Oops wait a second, The New Messiah is in office and the CDC and “the science” are still issuing conflicting data about what we should or should not do to protect us from COVID. I guess the Johnson vaccine is safe for children, or not. Masks are necessary or not or maybe just if you use two or not. Middle seats should be blocked or not. Biden and “the science” should be kicked to the curb or not. Meanwhile we are back to uprising, burning, looting and murder that blew the party of the jackass into the White House and “the science” at least is clear that protests that “don’t have to be peaceful” often kill innocent people . Perhaps we should put our faith in BLM and looters who have proven that wearing masks and hiding behind umbrellas is safe, and profitable enough for BLM leaders to buy millions of dollars of real estate. Seems we are getting reparations for the sins of our past of putting that Donkey Kong Biden in the White House.
