The largest and, most likely, easiest airport to find travel to is JFK.
We recommend renting a car for your travels around the East Coast, but if you must take public transportation from JFK, you can take the JFK Airport Shuttle to Grand Central station, which has an Amtrak line that runs directly to New Haven Union Station.
We have booked a hotel block at The Study at Yale Hotel for a discounted rate of $199/night for a standard room. Book online using this link or call The Study and mention the "Chao-Leung Wedding" for the discounted rate.
Reservations must be made by June 28th for the discounted rate.
We will have a free shuttle to transport guests between The Study and New Haven Lawn Club for the wedding.
Bradley International is a small airport north of Hartford, CT.
