Southwest Airlines will build a new maintenance facility at the Baltimore/Washington International Thurgood Marshall Airport. The announcement was made a ceremony marking Southwest’s 25th year of operation at the airport. The hangar will cost $130 million and be 130,000 sq. ft. and is scheduled to be completed by 2021. Gary Kelly, CEO of Southwest Airlines called the plans “a serious commitment” to the area. Southwest says about 240 aircraft fly through that airport daily and that it parks about 30 aircraft there nightly. The new facility will allow routine maintenance to take place inside according to Southwest Senior Vice President of Technical Operations Landon Nitschke.
