Alaska Airlines will stop flying out of Dallas Love Field in May, giving up a presence the carrier has fought bitterly to preserve for years.

Dallas Love Field is home to new technology that’s turning wind from airplanes into renewable energy. It’s an innovative idea that came from a North Texas surgeon.

Delta Airlines, Southwest Airlines and Alaska Airlines operate out of Love Field, Alaska Airlines uses two spots within Love Field’s 20 gates. So with Alaska Airlines not occupying the two lanes, this will open up two spots for the other airlines. It’s unclear which airline will use the gates that will be vacated by Alaska Airlines.

Alaska Airlines will start flying in and out of Dallas-Fort Worth International Airport only, consolidating their flights in North Texas.

Alaska is authorized to use just two gates at DAL, which federal law restricts to 20 gates. The airline has also been leasing some of its space to Delta Air Lines (DL), which operates 14 daily round-trips from DAL to its hub in Atlanta (ATL). It is also worth noting that Southwest Airlines’ (WN) headquarters is adjacent to DAL.

After years of testing, the airport has installed five turbines that capture jet wind exhaust and covert it to electricity. It's in partnership with the tech startup Jet Wind Corporation.
