Southwest Airlines is adding six red-eye flight destinations from BWI Marshall Airport to the West Coast.

Starting June 5, the airline will fly direct from Baltimore to Long Beach, San Francisco, San Jose and Ontario, all in California, as well as Portland, Oregon, and Seattle, the airport said in a news release.

BWI is Southwest’s busiest airport on the East Coast, according to the release, and already offers red-eye flights to Denver, Las Vegas, Los Angeles, Phoenix, Sacramento, California, and San Diego. In 2022 the state’s spending board approved around $425 million in construction contracts for renovations at Southwest’s concourses. The airport says “a substantial amount” of the project, which will connect the airport’s A and B concourses and install new baggage handling system, will be completed next year and then finished in 2026.

Around 300 flights depart BWI each day to about 90 destinations, the airport said.

“These new flights will foster tourism and business development for our state and region,” airport CEO Ricky Smith said in the release. “We are working to enhance the travel product for our customers while creating more opportunities for air service from our airline partners.”
