2170 and 2172 operate to BOS. You also free up additional space for travel to BOS, which would help. Even the 4:30 departure is pulling people fro, 2172 as it gives them another half hour but doesn't arrive too much later than 2172.
True, although how many folks get on 2170 and 2172 in WAS, BWI, and BAL and go all the way to PVD or past that? I can definitely see people going from WAS to STM or even NHV. But as far as travel between both ends of the corridor I'll have to look into that. Cause I actually am fairly curious to see what those numbers are like. But either way folks shifting to 2402 definitely frees up some seats for intermediate travel on 2170 and 2172 regardless of travel origin and destination.
