I was still in school in those days (late 60s early 70s) but would often go to the international passenger building terrace at El Dorado to watch the Super VC10 startup, taxi and takeoff on runway (13/31) - the only one in those days and of course fly over our house once a week.
Just to put this into a time frame The Prisoner, The Avengers and The Saint were all on local TV. I actually flew on a Britannia BOG - LHR in 1961 and back. A very long trip with all that Caribbean island hopping including CCS. Got a pic of family from our return trip Britannia in Barbados .
More recently 80s/90s until 2004 I flew the route as a pax in BA 747s but it was a great shame when BA stopped flying to BOG & CCS in 2004. Why? Never quite knew the reason for this as it was a historic route since BOAC. It was a very convenient route compared to what I have to do now - flights via Madrid, Paris or USA and no free drinks !
