Delta Air Lines is significantly expanding services from its hub at Seattle-Tacoma International Airport with four new destinations: Boston; Orlando; Pasco, Wash.; and Victoria, British Columbia.

“Through our growth, our team of nearly 3,000 Seattle-area employees is working diligently to support the needs of our Seattle customers and the hundreds of thousands of other customers we connect through Sea-Tac each year,” said Mike Medeiros, vice president of Seattle, Delta Air Lines. “These new flights are important additions and are consistent with Delta’s industry-leading commitment to capacity discipline. We look forward to showing our customers what Delta’s brand of thoughtful, reliable and innovative is all about as Seattle continues to take its place as a global commerce center.”

Later this year, the carrier will offer three daily flights to Tri-Cities Airport in Pasco from Nov. 1 and one daily flight to Orlando International Airport from Dec. 19. The following year, one daily flight to Boston’s Logan International Airport and three daily flights to Victoria International Airport will launch April 4, 2016. Delta will also expand its existing service to Bozeman Yellowstone International Airport from Saturday-only seasonal service to one daily year-round flight beginning Aug. 1.

Flights to Boston and Orlando will operate with Boeing 737-800 and 757-200 aircraft, respectively, while service to Bozeman, Pasco and Victoria will be operated by Delta Connection carrier SkyWest with two-class, 65-seat CRJ-700 jets.
