Overview

  • The new satellite just south of Terminal 1 will add 19 gates primarily for narrow-body aircraft, with flexibility for larger planes, and is slated to open in 2028.
  • City officials detailed a schedule that moves from heavy excavation later in 2025 to vertical construction in spring 2026 after years of preparatory taxiway and temporary gate work.
  • The project is part of the airport’s roughly $8.2 billion Terminal Area Plan that also includes a second satellite concourse, a new global terminal replacing Terminal 2, and an underground connector.
  • About 4,000 construction jobs are expected, with recent city reporting noting a 37% participation target for minority- and women-owned businesses.
  • Designs led by Skidmore, Owings & Merrill with Ross Barney Architects and JGMA feature a domed multi-tiered hall with an oculus, living greenery, and systems aimed at halving heating and cooling demand as the airfield continues handling roughly 120 flights per hour.
