The Horizon Air plane stolen from the Seattle-Tacoma International Airport is a Q400 Bombardier turboprop, a sleek aircraft with 76 seats.
Horizon Air, based at the Seattle-Tacoma airport, is owned by Seattle-based Alaska Air Group, which includes Alaska Airlines.
Both airlines serve as sister carriers and maintain connections and code-shares.
Alaska Air Group says there are 45 Q400s in the fleet.
