Enterprises and Loop Capital created a joint venture named JLC Capital to invest in Phase 2 of LaGuardia Airport's reconstruction. The same month, Delta broke ground on the last phase of the airport's reconstruction. On December 9, 2017, six airlines moved at LGA in anticipation of the new terminals. Alaska Airlines and JetBlue moved to the Marine Air Terminal. American consolidated in Terminal B. Frontier and Spirit depart from Terminal C and arrive at Terminal D. Since the move, there have been further changes with Alaska Airlines ending service to LaGuardia, JetBlue moving all but Boston flights to Terminal B, and Spirit consolidating its operations in Terminal A. LaGuardia Gateway Partners, which manages the construction of Terminal B, has completed most of the complex. The first half of the seven-level West Parking Garage opened in February 2018, with 1,600 of 3,100 parking spaces being made available, and the rest of the garage was opened later that year. Eleven new gates at Terminal B opened on December 1, 2018, and were used by Air Canada, American Airlines, and Southwest Airlines. Five additional gates opened on June 2, 2019, when United relocated most of its operations to the new concourse. The new space included a concourse with a ceiling, food concessions, an FAO Schwarz toy store, and an indoor play area. The new headhouse at Terminal B opened on June 13, 2020, along with the new connector to the Eastern Concourse. On August 5, 2020, American opened the first seven gates of the Western Concourse, with ten additional gates and the bridge connector scheduled to open at the end of 2021. The second bridge connecting to Terminal B was later completed and opened to the public on January 27, 2022. On the east side of the airport, Delta is consolidating its two terminals, Terminal C and D, into a centralized Terminal C headhouse, which is located on the former Terminal D parking site. In addition, Delta is rebuilding its airside facilities into four "finger" concourses. The first concourse to open was Concourse G on the eastern end of the airport, which opened on October 29, 2019. Delta Shuttle flights moved to the Concourse G on November 16, 2019. On June 4, 2022, Delta unveiled its new Terminal C headhouse to the public in tandem with concourse E, which boasts 10 narrow body gates. The Terminal C headhouse consolidates the former Terminal C
