Boys boys boys do you really think the general public in this day and age really check an airports web sites for time tables??? Yes tell them where and who go there but that's all needed in this computer age!
Plus airlines these days change time/dates etc so oftern during the season far better get up to date info from horses mouth?!
KLM change their objectives all the time for example last year KLM were always the cheapest hub airport from NCL, now this year this has changed for Eastwards travel Emirates seem cheapest most times I've tried! Emirates have not changed fares drastically KLM have, taking less discounted Y fares. So less discount fares less people!!
