xyz_pilot. Yep, this is not a problem for me - I was just trying to put some more info into the reason for all the flights arriving at LHR in the first 90 mins of the day (apart from the obvious curfew). I am well aware that Biz pax set the agenda. When I am biz pax, I am more than happy about that.
KLM to JNB are probably doing the daylight return, if their route has become more of a tourist one and they want to lower prices.
I agree with rsoman that allowing 60/90 mins for connection at LHR at that time of the day is not sensible. People still seem to think that a/c will arrive on time and that the jet-way will kiss the door at
exactly the time on the itinerary.
For LHR and other Europeans hubs, the removal of the curfew would fix the problem and remove some pollution. But, as we know, LHR is in both the Right and Wrong place! The airport has been 'fudged' by politicians since it's inception and there is no political will to fix the problem. Nominally, move the airport or move the people that live around it.
