NYC to Nantucket?
 

I'm trying to figure out the best way to get to Nantucket from NYC. Jetblue has a flight out of JFK which, for some reason, takes an hour and a half flight time. Or I can take Amtrak to Providence, cab to airport and CapeAir to ACK. I usually leave from DCA or BWI so I'm not familiar with getting there from NYC. Also, are there any passenger boats from New York to Nantucket?
Thanks for the info.

US Air has flights from LGA.

No boats from NYC to Nantucket.

Continental has flights from Newark.

Thanks!

You need to watch the USAir flights since some of them stop in Hyannis or the Vineyard before coming here.

The JetBlue flight might do that too, but when my family takes them from Richmond, connecting at LGA, they haven't mentioned the scheduled length of the flight so it may be a schedule change.

What I must say is that getting to Nantucket is very much dependent on the weather, and in the summer the issue is fog. If you fly here from DCA, you know that. Many don't, and the atmosphere in the departure lounges at LGA can get a little testy.
