I know several -400 rated guys flying in dubious parts of the planet looking to get back to Europe. GSS in STN will offer up a few too. As for the 330/340 there must be quite a few Emirates/Qatar/Etihad folks looking to get out of the sandpit.
Who knows, in a few years time you'll be in BA anyway, once Delta/AF screw up their big share of Virgin (with lots of protected commands too!)
