DUB?
How about DUB for a start? Currently no direct flights to Asia or Africa (SIA has just ended its flights), but plenty of potential* - particularly if you feed into another airline's network at a major M/E or African hub?
SIA Cargo operated a 744F; EY is doing very well on cargo, as EI has been (although it is soon to cut DXB route, to focus on US routes) ... Irish govt has strong trade growth plans for Asia.
You could do a lot worse ...
