A single image, taken on a routine flight from Helsinki to Copenhagen, has ignited a firestorm of debate that’s rippling across social media. It shows a plus-sized man struggling to fit into a standard airline seat, his discomfort palpable. The photo was first posted by consumer advocate Christopher Elliott, then later resurfaced thanks to the Miami-based hip-hop group Pretty Ricky, who added fuel to the fire with a caption that struck a nerve.

“Airlines will have to have something in place for plus-sized passengers,” the group wrote. “This image was taken recently on a flight showing how difficult it is for people who are bigger than one seat. It’s also difficult for those sitting next to them. It’s a difficult situation because the airline will need to think of a happy medium.”

That “happy medium” set off thousands of comments—many passionate, some compassionate, others cutting.
