If you're looking to fly straight into Connecticut, this is the airport you should use. Prices are often comparable to flying into Boston or NYC, but sometimes slightly higher.
If you're looking to travel a little more while you are over on the East Coast, flying into Boston could be a good option. Boston is about a 1.5-hour drive from where we are located in Connecticut.
Another option would be to fly into NYC to do some sightseeing there. JFK is about a 2 hour drive from where we are located in Connecticut.
If you are looking to travel to NYC, the Amtrak train leaving from Hartford Union Station is a great option. Tickets are usually around 20-30 dollars roundtrip and it'll take you straight to Penn Station. You can also take the same train to Boston.
