The new 105,000 sq ft concourse at New York's LaGuardia Airport (LGA) is set to be open to the public as part of an $8 billion transformation of the airport.
Next week will see the opening of the new concourse and seven gates at Terminal C, which will be the home of Delta's flights at the airport.
Delta operates more than 275 peak-day departures from its LGA hub and began construction on the $4 billion replacement of Terminals C and D in 2017.
Delta CEO Ed Bastian said: "Two years ago, we set out to build a state-of-the-art facility at LaGuardia Airport, an airport that our customers and the people of New York deserve. Thanks to the commitment and hard work of the Delta team and our many partners, today marks the beginning of a new era for millions of Delta customers at LaGuardia. The excitement that is building here is palpable and contagious, and we are already looking ahead to many more milestones to come."
When complete, the new terminal will feature 37 gates across four concourses connected by a centralised and streamlined check-in lobby, security checkpoint, and baggage claim.
