Having a dad that works for SAS, I get the oppertunity to travel as Jump seat pax frequently. I allways recieve a briefing in how to opperate the Oxygen mask and how to evacuate, both by rope and the traditional way. The crew allways make shure I know how to operate the jump seat quickly.
Of what I've understood, SAS employs the jump seat quite often on overbooked flights.
However, relatives to SAS employees generally get priority.
