2nd runway is still needed but the flexible opening hours is useful to pacify the locals until such times that extended/permanent opening from 0630 to 2200 is needed. In a very idle moment, I looked at all the scheduled services on a Monday morning just to see what kind of connecting opportunities exist - there are some 98 scheduled service movements from 0630 to 0930; 44 of them between 0800 and 0859. Add in the charters and you can see where the need arises for the 2nd runway. Having said that, they may be able to cope with 50 movements on 1 runway but I'd prefer it to pegged at about 44 an hour maximum.
