San Diego International airport's new 10-gate expansion will allow United Airlines and other carriers consolidate their operations, while freeing gates elsewhere at the airport.
Chicago-based United will use seven gates (38-40 and 43-46) in terminal two west, which includes the so-called Green Build expansion that opens on 13 August, the airport disclosed today. Delta Air Lines will use five gates (47-51), JetBlue Airways one (36) and US Airways three (33-35).
The Green Build includes gates 42 to 51, as well as renovations and upgrades to other spaces in terminal two west, which includes gates 33 to 41, and a new second level vehicle roadway in front of the terminal.
United previously operated from five gates in terminal one as well as two gates in terminal two west, a legacy of the separate Continental Airlines and United operations at the airport prior to their 2010 merger.
With the carrier's consolidation in terminal two west, Alaska Airlines could now expand its operations into the four vacated gates that are adjacent to its own three - the airlines share one additional gate - in terminal one.
Seattle-based Alaska has expanded significantly at San Diego since the beginning of 2012. It has added new nonstops to Boston, Fresno, Kauai, Monterey, Orlando and Santa Rosa during that period, and will launch new seasonal service to Mammoth, California, on 19 December.
The airline was the fifth largest carrier at San Diego with a 6.9% share of the airport's 16.8 million enplaned passengers during the year ending 31 March, according to US Department of Transportation (DOT) data. Its growth helped it surpass US Airways, which held the fifth spot a year earlier.
United was the second largest with a 14.4% share of enplaned passengers after Southwest Airlines with a 38.5% share, the DOT shows.
Alaska did not respond to inquiries regarding any planned expansions into United's former gates at San Diego.
San Diego is focused on renovating terminal one and building a consolidated rental car facility on the north side of the airfield, with a potential connection to the region's Trolley rail system, after the Green Build opens.
