The longest runway at BOS is 10000ft long, which isn't quite enough for a fully loaded 747/777 bound for Asia. At SFO, especially during the winter when they really load those 747s up with fuel due to strong headwinds, most of the flights I've been on have used up almost all of the 11000ft runway they have there (28R).
