First there were snakes on a plane. Now penguins are taking the air. Or at least that's what happened on Delta flight 1641 from San Antonio to Atlanta on March 8th, as captured in this adorable YouTube video. According to Yahoo News, the pilot made a special announcement asking if anyone was allergic to penguins. When the plane reached cruising altitude, the pair took a stroll down the first class cabin greeting passengers who snapped and filmed the cuddly creatures.
