TF-ATO has a pylon problem which should be sorted before Christmas. The 767s are or will be in Africa for the winter, though I heard talk of one in South America, but they will be back in UK for the summer. Since European bought some ex-BA 747s I doubt that Atlanta's 747s will get much further into UK than Manston this summer.
I also hear that some Swedish outfit is currently offering 747s at ridiculous rates.
