Elin Ersson, whose Facebook page says she is a student at Gothenburg University, bought a ticket for the flight from Gothenburg to Turkey after she and other asylum activists found out that an Afghan was due to be deported on it, according to Swedish press reports.
As she entered the plane Ersson started to live-stream her protest in English. The video received more than half a million hits on Tuesday.
Facing both sympathy and hostility from passengers, the footage shows Ersson struggling to keep her composure.
“I don’t want a man’s life to be taken away just because you don’t want to miss your flight,” she says. “I am not going to sit down until the person is off the plane.”
