Where are you coming from. And what part of NY is your business. If it is on Long Island I think JFK, or LGA. If it's the city or upstate I suggest EWR, and of course Continental Airlines if the fares can work for you.
I would fly Continental, IND-CLE-White Plains. Those flights are Embraer jets. The IND-CLE is an ERJ135, brand new. Also, if possible I would fly into White Plains-Westchester County because EWR,JFK,LGA are PACKED all the time, Also you could fly Delta w/a connection at CVG. Or USAirways w/a connection in PIT. There are many choices.
life wasn't worth the balance, or the crumpled paper it was written on
