This luxury airport lounge has a hidden room for its most exclusive customers

Over the past decade, New York's John F. Kennedy International Airport has made a concerted effort to improve customer experience and integrate a higher level of luxury amenities. One of the most recent and impressive additions is the Etihad Airways Premium Lounge located inside JFK's Terminal 4.

"Everything we do at Etihad is about providing unparalleled luxury," Etihad senior vice president for the Americas, Martin Drew, told Business Insider during a tour of the facility. "We don't necessarily benchmark ourselves just against other airlines, but more so against some of the finest hotels and restaurants in the world."

Opened at the end of 2015, the lounge extends the Etihad's premium service beyond the aircraft - putting the airline in a prime position to attract highly lucrative business and high-class leisure travelers. In addition to the lounge, the Abu Dhabi-based airline is ramping up its New York operation with the adoption of the Airbus A380 superjumbo on its JFK-bound flights.
