SeaTac's Alaska Airlines flew non-stop from Sea-Tac Airport to Cancun for nine years before halting the service in 2010.
Now it has told the Mexican government it wants to resume that service beginning in November.
When the airline canceled its flights to the Mexican resort four years ago, it was in the midst of a big push into Hawaii from the West Coast.
Now that the Hawaiian market has reached maturity, and airfares are increasing to Mexico, the airline says it wants to revisit the Cancun market.
Alaska's flight would be the only non-stop flight from Seattle to the east coast of Mexico. Alaska already is the largest provider of non-stop flights from the West Coast to Mexico with flights to Loreto, Los Cabos, Mazatlan, Puerto Vallarta, Manzanillo, Ixtapa/Zihuatenejo, Mexico City and Guadalajara.
If Mexican authorities and the federal Department of Transportation approve, Alaska will begin seasonal service Nov. 6.
