Runway 15L/33R at Boston Logan is only 2500 ft, which is barely long enough for a Cessna, let alone an airliner. I’m wondering if anyone knows why this runway was built or what purpose it serves. I find it a bit odd considering KBOS is certainly not intended for GA use. I don’t think there are any other class B airports in the country with such a short runway.
15L/35R is actually used for GA purposes although most of the time it is just used as a taxiway. KBOS has a GA ramp and FBO just north of the International Terminal (E). It may surprise you that most of the large Class B airports still have GA traffic and the facilities to support them. Also, a fully loaded C172 only needs about 1200 feet of runway for takeoff at 40C/sea level and 650 to land, so 2550 feet is plenty of runway.
