There's a budget airline based in Cologne, Germany, called Germanwings.
It competes with other European budget airlines, including one called EasyJet, which is based in London, England.
It seems Germanwings wanted to advertise its superiority over EasyJet. To do so, they installed actors aboard an Easyjet flight, and filmed them (presumably surreptitiously, and certainly without EasyJet's permission!). Here's the result.
Note the amusement of the Easyjet passengers when the final boards are displayed. Cheeky, but very funny!
