If flights to/from AUA require a USCIS capable station, then no since HPN lacks those facilities. If AUA pax are able to clear US customs/immigration in AUA itself (like Air Canada pax do at YYZ for US-bound flights) then it's a possibility. I'd personally be surprised if the HPN market could support such service in the first place though.

Personally I wish they'd add flights to BOS so we could access B6 flights to the west coast without having to drive down to JFK...
