The route

The direct connection between Seattle-Tacoma International Airport and Paris Charles de Gaulle serves as a vital summer link between the Pacific Northwest and Continental Europe. Operated by Delta Air Lines, this route offers travelers a premium nonstop experience, bypassing traditional East Coast layovers and connecting two major global aviation hubs.

This seasonal corridor utilizes Delta's flagship wide-body aircraft to bridge the 5,000-mile gap between Washington State and France. It is primarily designed to capture peak summer tourism demand and high-level business travel within the SkyTeam network.

As one of the few nonstop options from the PNW to France, this route significantly reduces total travel time. For SkyTeam loyalists, it provides a seamless transition from Delta's Seattle hub to Air France's primary base in Paris.
