One of my favourite in-flight moments was on an Air New Zealand 747-400 flying from LHR-LAX and I had chance to go and sit on the flight deck, superb experience, awesome views.
My favourite flight however was on 6th July 2000. It was flight SN2174, my first ever flight with Sabena. It was also my first flight on an Avro RJ. The steward greeted us with “welcome aboard the best flight of your life”. During the safety demonstration he said “when we crash into the sea make sure you don’t get eaten by the sharks”. He was making jokes throughout the flight, which made it a fun experience. When we landed his final words were “welcome to Brussels. Sorry for the delay but what’s fifteen minutes in a lifetime!!” I only hope he continues to work for SN Brussels.
