U.S. Southwest Airlines plans to co-fund a new $130 million regional maintenance facility at Baltimore, Washington International Airport, to better meet its needs at the second busiest airport in its network.

Southwest will invest $80 million, with the Maryland Aviation Administration contributing the remaining $50 million.

The three-bay hangar will be complementing six maintenance hangars in Atlanta, Chicago, Dallas, Houston, Orlando and Phoenix. The facility will include additional exterior parking spots for eight aircraft, as well as office space.

Construction of the hangar is expected to create 450 jobs. Construction of the 12,080 square meter line maintenance facility will begin early next year, with completion in 2021.
