I share Cough's reservations about point merge.
The plan I've seen for my airfield has all arrivals passing abeam the field at 10 or 11000'. This represents an extra 10-15 miles for every arriving aircraft.
I've questioned the logic of this and been told the benefit of an extra 3000' of climb for the departure far outweighs the fuel burn of the extra track miles inbound and that is what the airlines want.
Have the airlines been told every arrival will have to fly an extra 10/15 miles?
