The 35-second clip, shared Wednesday on Twitter by Erik Olvera, shows the woman, who’s not wearing shoes or socks, swiping away on the plane’s media screen with her toes.
“I fly a lot and this, by far, is the most disgusting thing I’ve ever seen on a plane,” Olvera tweeted. "Bringing #antibacterialwipes. Where’s @NaomiCampbell when you need her in-flight wipe down advice?”
The video has since gone viral with more than 2 million views and 3,000 retweets.
Twitter users appeared to agree that the passenger’s behavior was unsanitary.
“What the hell is wrong with people,” a Twitter user commented.
Another tweeted, “OMG! Pigs do fly!”
“That person looks like they’ve practiced foot scrolling a lot,” another Twitter user wrote.
“In 1st class looking like low class,” someone else tweeted.
Others jokingly questioned whether the woman had arms, to which Olvera replied: “Her arms were just fine. She carried her expensive luggage on/off the plane."
“Also used them to throw back cocktails and take snacks from the galley when the FA [flight attendant] wasn’t around,” he added.
A Twitter user slammed the passenger’s behavior as “passive-aggressive” and argued that it was “indicative of entitlement issues.”
“A confrontation would probably only result in them playing the victim or pretending to have a handicap -- anything that allows them to get attention and rage,” the person tweeted. “The kind of person who'll never admit they're wrong.”
