Cape Air announced this week that it will expand its service from Hyannis, Nantucket and Martha’s Vineyard to John F. Kennedy International Airport in New York city.

Year-round air service will begin in September.

The expanded service is in response to demand during the off-season, a press release said.

Cape Air has been operating for 30 years, and is the Vineyard’s only year-round carrier.

For information on the new service is available at or by calling 800-CAPE-AIR.
