I hear Kalitta and Southern are hiring too... I don't work at either, but if you are looking for something interesting/exotic and you ultimately want to jump to a legacy and take the ultra slow-road to the Captain seat, why not get some 747-400 (Kalitta operates them and Southern will be adding 400s shortly) time in the interim...
Your new office awaits:

I agree with J-rod - go do something different if you want to hang around and wait for the Legacies. If you already have the required PIC time to be competitive at the majors, go fly a 747 and see the world. Why not? I have also heard that Southern, Kalitta and World are hiring. You might just like it enough to stay... I know a senior Kalitta Capt from my freighter days and he loves the flying. I flew the 747 myself in the latter 90s and loved it. Best and most exciting flying I ever did and I am thankful for the opportunity.
