We recommend booking a flight from JFK and LGA to Hyannis Airport (HYA). These flights are operated by Jetblue and American during the summer months and make for an easy trip from NYC to cape cod! These flights may not be available to book yet, but you should be able to book them as we get closer to 2024.
The easiest way to get to the cape for those outside of the northeast is to book a flight to Boston Logan Airport. From Boston it is a 1.5 hour drive to Dennis. You can also take a bus from the airport straight to Hyannis (Plymouth Brockton Bus line) or take the CapeFLYER train from Boston to Hyannis.
