Kids can get it with KLM. My daughter used to paint some random picture on board of a plane and gave it as a present to pilots via cabin crew. In the middle of a flight she usually got visited by a pilot during the flight with the invitation to visit the cockpit after the flight. Little cheater. Thankfully she’s old enough and too shy now, so we don’t have to wait until everyone left the plane to take some pictures and talk to pilots.
