I don't think BA will be selling anything - they've withdrawn the 744s from the market a) because they couldn't achieve required pricing and b) because they're all flying full. They now say that the 744s will be in the fleet for the foreseeable future. Meanwhile Cathay, finally accepting that they can't get RR-powered versions have, together with Dragonair, agreed to buy 8 744s from SIA of which most, if not all, are for conversion to freighters. CX looking for at least 8 more.
