David – as you may remember year 2000 scared the pants off many people as they predicted planes would fall out of the sky. In fact the only good thing that came out of the year 2000 fiasco was that I changed jobs !!
However the 2000 nonsense returned yesterday as a particular low cost airline lets call them FlyBy managed to reek havoc with preventing passengers from printing their boarding passes as the system decided that 29/2/2012 was not a valid date.
So my advice is before flying with any airline is to write a script to check all the dates that you might fly on – and if it fails with any leap year – fly with someone else
