Those 9 extra BF seats are a big deal though. Same with the longer stage length the 767 allows. They're not really 1:1 swapable except on shorter stages, or lower BF revenue stages. (If you can sell every one of those 25 BF seats AND take more cargo, you're sure as heck going to want the 767-200 on that route.)
