As JFK becomes 777, FRA will see 747, along with LAX.
For inter-Asia, currently PVG/NRT/HKG frequently see 747 for their morning flights. From this winter schedule, only PVG keeps daily morning 747 flight, while other routes (PVG/NRT/HKG) will have 3-4 weekly evening 747 flights. It seems OZ won't sell F for HKG and NRT flights, though, which means aircraft swap will happen a lot for these two.
