At long last, New York’s major airports are getting some much-needed upgrades. We’ve already written about some of them, like LaGuardia’s rebuilt Terminal B, JFK’s upcoming new Terminal One, and Newark’s replacement Terminal A.

Out of the multiple megaprojects that are underway, few are bigger than JFK’s Terminal 6, slated to open in the first half of next year. The team behind the $4.2 billion project invited us to join a tour of the active construction site. We loved the behind-the-scenes look at a major terminal coming together, and we came away with a better understanding of what flyers can expect once it is completed.

There will be a HUGE passenger experience boost compared with JFK’s older terminals. T6 will showcase JFK’s status as a world airport, hosting long-haul international airlines from multiple continents along with a few domestic and low-cost airlines. The building will sport plenty of high-tech features, some for the sake of improved passenger experience, and others boosting the sustainability and efficiency of behind-the-scenes operations. Importantly there will be plenty to keep people entertained, including a standout list of lounges, outposts of multiple famous NYC eateries, and some great planespotting potential.

Read on for more of what you can expect when JFK’s Terminal 6 opens in a few months.
