Anyone know which airlines release J class seats more than 2 at a time. In my experience, it includes:

BD (short-haul at least)
LH (selected dates and routes only long-haul, lots short-haul)
TK (long-haul)

TG is frustrating as they only release 2 at a time but am looking for a Thailand trip (EDI-BKK). I need 3 seats but can only get 2 so am having to route via IST with TK although able to use LH on the way out.

Any other experiences to share?
