Manchester-Boston Regional Airport (MHT) is the closest to the seacoast area — 25 minutes from Concord, and roughly 50 minutes from Rye and Portsmouth by car
We recommend renting a car if you fly into MHT, but taxis & shuttles are available as well
Boston Logan International Airport (BOS) is just over one hour from Concord, Rye, and Portsmouth by car
Car rentals & taxis available, plus a C&J Bus that will take you straight to Portsmouth
C&J offers affordable, reliable, and comfortable service between New York City, Boston, and Portsmouth (Svati has taken it many times!)
