Compass Airlines (United States of America) is closing its base at Seattle Tacoma International and laying off 197 people effective May 1, according to a report in the Seattle Times. The regional operator disclosed the redundancies in early March after it filed a notice with the state Employment Security Department.

The Minneapolis-based regional carrier flies its E175 aircraft for Delta Air Lines (DL, Atlanta Hartsfield Jackson) at the airport, however, it lost its contract with the Skyteam carrier last August. According to the ch-aviation schedules module, Compass operates services to Bozeman, Sacramento International, San José, US, Santa Ana, CA, and Spokane International from Seattle Tacoma on behalf of Delta.

Compass’ check-in and gate allocation at Seattle Tacoma was part of the facilities leased by Delta. The Atlanta-based carrier is replacing the flying operated by Compass with another regional partner, SkyWest Airlines (OO, Salt Lake City), as well as upgrading some other flights to mainline Delta aircraft.

As its Delta operation winds down over a period of 11 months, Compass’s fleet is shrinking to just 20 jets. According to ch-aviation fleets module, the airline is currently operating thirty-seven E175s, of which six are listed as inactive. The regional airline’s only other contract is with American Airlines (AA, Dallas/Fort Worth). The majority of its flights for the Oneworld carrier is operated from its base at Los Angeles International, where it flies to 21 destinations.
