My point was that domestic pricing is getting pretty crazy, I think you would have to be living in a cave note to see this. The price differential between Domestic F and International J ON SOME ROUTES may not be as great as in previous years. I didn't even look at what F was on that ticket given the $1300 coach fare, I can't / won't buy it. However, as jsloan stated, the cabin size is generally much smaller hence less potential supply of domestic F seats (again on some routes).
