I have been to HPN and it is a small regional airport. It is located off of I-684 in White Plains, NY. The primary use of the airport is by business passengers, as I recall White Plains has a number of companies located there. It is a half hour drive from NYC, there is also a local bus that goes from the airport to White Plains where you can get a bus to NYC. The largest aircraft that flies there is probably an M80 or 737, there are many more prop and RJ (regional/exp airlines) planes that serve HPN. As I recall, UA has 4 737's to ORD, ACA has 4 J31's to IAD, AA has 4 100's to ORD, BEX has 12 SF3's to BOS (just to tell u, many less flts op on wknds), CO Exp has 4 ERJ'S to CLE, NW has 2 D9S and 3 ARJ's to DTW, also a D9S and ARJ to MSP, Comair has 3 CRJ's to CVG, US EXP has flts to BWI (4), BOS (10), PHL (5), PIT (1), POU (3), ROC (4), SYR (3), IAD (4), DCA (6). Also US mainline has 2 PIT jets. There is a small fenced observation deck. There is 1 small bag claim and hertz, avis, and national. Also a restaurant overlooking the field and a news stand.
