Ah I see, thanks.
I recently got back from D.C on a flight to Westchester County Airport. The flight got in roughly ~15 minutes before the W12 bus comes to White Plains. The whole process went smooth, and among the almost fully booked flight, mostly everyone was heading to White Plains, yet only me and 4 other people actually got on the bus. The bus stop area isn't well designated, and I asked around while waiting for the bus and half the people didn't know there even was a bus to White Plains.
Which makes me think, could the reason the Airlink and the W12 itself failed is because no one knows it even exists?
