Delta just shamed other carriers for refusing to block middle seats during the COVID-19 pandemic.
A tweet posted to the carrier's main Twitter account read, "A haunted house, but they're not blocking middle seats." Delta is currently one of two major US airlines blocking middle seats as a COVID-19 safety precaution during the rest of 2020.
Alaskan Airlines announced Thursday the company would extend blocking middle seats onboard until January 6, 2021.
American, United, JetBlue, Frontier, Allegiant, Spirit, and Sun Country have stopped blocking middle seats, and Southwest announced it would do so ahead of the holidays beginning December 1.
Despite the relaxed rules blocking middle seats on airplanes, the risk of contracting the novel virus remains high as the US entered its 3rd wave of cases this month. The number of new cases have gone up in 41 states, and the US is seeing an average of more than 50,000 new cases per day.
Epidemiologists say sitting too close together on air planes increases the risk of contracting COVID-19 from a nearby passenger. "The main risk is people in the rows [and seats] around you," Salvatore Pardo, MD, the chair of emergency medicine Northwell Health's Long Island Jewish Valley Stream Hospital, told Business Insider's Tom Pallini.
