Not true, this meme is probably made by an airline employee who will be laid off after 9/30 (the Coronavirus Aid Package prohibited airlines from mass layoffs until 10/1).
From the CDC: Social distancing is difficult on crowded flights, and sitting within 6 feet of others, sometimes for hours, may increase your risk of getting COVID-19.
Don't put your life at risk by believing this crap. @Marhew cares more about his/her job than your safety.
