The €148 million project adds 11 gates and 75,000sqft to Terminal 4's Concourse B and continues Delta's $1.2 billion investment to enhance and expand the terminal.
Through this latest investment, Delta is significantly enhancing the customer experience at Terminal 4 and Terminal 2 by relocating a majority of its connection flights at JFK from Terminal 2 to the expanded Concourse B in Terminal 4.
This will streamline travel for those with connecting flights at JFK and enhance access to amenities at both terminals.
Authority executive director, Pat Foye, says: “The Port Authority and our airline partners are committed to continuing our initiatives to transform and modernize JFK Airport into a world-class facility befitting the hundreds of thousands of people who fly in and out of our region each day.
"We applaud Delta's investment in New York City's airports to modernize and expand its terminal operations, and we will continue to work with all of our stakeholders to make sure JFK continues to serve as a premier source of job creation and economic activity."
The new gates at Terminal 4 will feature enclosed jet bridges and offer customers proximity to a flagship Sky Club and chef-driven restaurants, and facilitates intra-terminal connections with the addition of a new JFK Jitney bus stop at the end of Concourse B in Terminal 4 near the new gates.
This will complement the existing stops located by gate B18 at the base of Concourse B in Terminal 4 and by gate C60 at Terminal 2.
Ed Bastian, Delta's president, says: “The newest enhancements at Terminal 4 underscore the significant investment Delta is making in New York City's airport, nearly $2 billion over the last six years.
"Our customers and employees are benefitting from substantial enhancements to our JFK operations, and we thank our partners at the Port Authority of New York and New Jersey and JFKIAT for working with Delta to create a world-class facility that meet, and, we believe, exceeds the expectations of today's modern travellers."
As a result of the expansion at Terminal 4, Delta customers at Terminal 2 will also enjoy an improved experience, as all Delta flights that will continue to operate there will use climate-controlled jet bridges.
Customers will also have access to a renovated Sky Club, convenient iPad stations and a chef-driven food and beverage program featuring seven food and beverage concepts, fresh markets, coffee shops and concierge services.
In Q2 2015, the Terminal 2 bus stop will be refreshed, with escalators and elevators installed.
The expanded Terminal 4, which JFKIAT has successfully operated for more than a decade, improves the customer experience for the 12 million passengers Delta serves at JFK annually, and builds on Delta's $1.2 billion redevelopment of Terminal 4, which opened in May 2013.
That expansion featured nine new and seven renovated international gates; improved and renovated check-in areas, including a dedicated Sky Priority check-in area; a centralized security checkpoint; new dining and retail offerings; a new 24,000 square-foot flagship Delta Sky Club with the first-ever Sky Deck outdoor terrace; dual taxiways for less congestion and shorter taxi times; and improved Customs and Border Protection and baggage claim facilities.
Gert-Jan de Graaff, president and CEO, JFKIAT, says: “JFKIAT is pleased to join Delta to unveil the latest expansion at JFK Terminal 4. We applaud the company's commitment to develop an infrastructure at JFK that truly caters to the modern traveller."
