He goes to both LW arenas and flies a few sorties in each. For you that want to fly jets to get him beware that if you do kill him you get a boot with a 5 minute ban. You will lose your perks, and even if you don't shoot him down Santa flies very fast so most of his escorts are going to be in jets. Best bet is to find where he is at and climb in a fast prop plane. Pony, N jug, or Ta 152 do great for diving in on him. The sortie before I vulched him last year I was in a jet and there were so many enemies flying by him I don't even know which one got me.
