A new concourse at Terminal 4 is scheduled to open in 2021. Southwest, the second largest carrier in Phoenix behind American, needs the new gates for its larger aircraft. The new gates have to potential to increase the frequency of Southwest’s flights and add destinations for Valley travelers.
Phoenix City Councilman Daniel Valenzuela praised the expansion, noting that Sky Harbor already supports about 240,000 regional jobs and has a total economic impact of nearly $30 billion. The new concourse, the eighth and final one at Terminal 4, will further expand the airport’s economic footprint.
