i would think that lhr-jfk would definitely be one of the most profitable, but not based on what happens in coach. biz and first class airfares are routinely higher out of the uk than most other european countries. the fact that us-uk open skies can't be done because of the fierce battle for slots at lhr also lead me to believe that this route is a gem for those that have it. i'm aa plat, and i usually don't try to upgrade it, as i feel the route is too short to give them 25k for, but i rarely see that biz cabin with any open seats, and there are always people up in first as well.
i also puy jfk-lax on the list, cause i can never get an upgrade as a plat as most of the seats are purchased in biz class by hollywood types.
