The Royal Dutch Airlines official Twitter account attempted to show their support for the gay movement, but people noticed something rather ironic about their imagery.
"It doesn't matter who you click with," they tweeted, "Happy [Pride Amsterdam]."
But, as some on social media noticed, their messaging was off because the seat buckle operation only works one way. And that seems counter to their attempted LGBT messaging.
"Um if you use the top two seat belts and the plane has turbulence, you could die," said Ben Shapiro.
"Someone might want to explain to this airline that two of those three pairs of seat belts will never actually click," tweeted Sean Davis.
"Only one of these seat belts will perform the intended function," tweeted Jim Treacher. "I realize that noticing this means I'm bigoted against the LGBT community."
Others on social media had a field day with the social justice graphic failure, noting that they accidentally affirmed the primacy of traditional marriage instead.
Royal Dutch Airlines has not responded to the social media sarcasm.
