Oddly enough (according to AAs chart at least) Europe will cost 55K in business class even if you fly from LAX-JFK in business on a 3 class plane as long as you fly on AA from JFK-Europe. Fly on a partner to Europe and you're hit with the 7.5K penalty for connecting from LAX-JFK in business on a 3 class plane.
Think it's a typo on AAs part?
