Starting next summer, San Diego will have additional nonstop service to Seattle, courtesy of Delta Airlines.

The flights, which will begin operating June 2, will depart four times a day, expanding the nonstop service already offered by Alaska Airlines.

The new Delta flights will depart at 6:45 a.m., 10:15 a.m., 2 p.m. and 5:05 p.m. Alaska Airlines is currently the only other airline offering nonstop service between San Diego and Seattle-Tacoma International Airport.

Delta’s new service between Lindbergh Field and Seattle-Tacoma International Airport will be operated by Delta Connection carrier SkyWest Airlines using 76-seat, two-class CRJ-900s. Each aircraft is equipped with first class and economy comfort seating, as well as onboard wi-fi.

“We have continued to strategically add service from key markets in an effort to support passenger demand for our expanding international destinations,” said Mike Medeiros, Delta’s vice president – Seattle. “Delta’s most recent additions will provide our customers with one-stop access to and from several of the top international and domestic destinations via our growing global gateway in Seattle.”
