Three of his female relatives were seated next to men they did not know. The British Airways pilot, however, was evidently a firm anti-dhimmi, and would have none of it: when the Sheikh complained, he ordered him and his entourage off the plane.

MILAN (Reuters) - A Qatar sheikh held up a British Airways flight at Milan’s Linate airport for nearly three hours after discovering three of his female relatives had been seated next to men they did not know.

When none of the other business class passengers agreed to swap seats, the sheikh, a member of Qatar’s ruling family, went to the pilot, who had already started the engine, to complain, an airport official said.

But the pilot ordered him and his traveling companions, the three women, two men, a cook and a servant, off the plane.
