After flying nonstop from BTR to Charlotte, Atlanta, Dallas or Houston, it’s a short hop to some of New York’s overlooked underground sensations. A purrfect start? Roosevelt Island’s cat sanctuary. Escape to weird museums dedicated to Houdini, eclectic antiques and outlandish tattoos. Sneak into Please Don’t Tell, NYC’s secretive speakeasy. Fly up, up and away to Brooklyn’s Superhero Supply store or bizarre night bazaar. Then cuddle up for Coney Island’s “most romantic ride in the world.” Visit your favorite travel site for roundtrip fares as low as $251, and be sure to check out www.flybtr.com for more trip ideas.
