The seat map shown by ExpertFlyer shows all Envoy seats have been assigned, as well as probably 80-85% of Coach. Still could be some cruise operator that has assigned all the seats to themselves perhaps, but since there are seats actually assigned rather than J= 0 but a bunch of seats unassigned, I would think there are probably actual bookings already made for these seats, and that only onesy-twosy stuff might maybe open up. A lot of times when consolidators make bulk purchases, they don't actually assign the seats till very close to the travel date.
