Vegas Agent could probably give a little better advice, but I think on most predominantly leisure routes, LAS, MCO. That NWA traditionally does not have a lot of Elites flying that route on any given day. An exception could be a convention in town. However, due to this history, they can safely oversell the back by 15-18 people and still get everyone on the plane. All elites and companions get upgrades first, then they just randomly move people to the front. The flight goes out full, NWA sold more coach seats, the bump ups are happy they bought coach and got to fly in first, everyone wins.
