Southwest Airlines will suspend its Seattle-Nashville non-stop service for the winter beginning Nov. 7, new schedules show.
Southwest in recent years has suspended its Nashville non-stop service from Sea-Tac during the winter months when tourist traffic is lower.
In other airline developments, SeaTac's Alaska Airlines is dropping out of the highly competitive nonstop Portland-Denver market in early September. Four airlines, United, Frontier, Southwest and Alaska, now connect the two cities nonstop. Alaska, with just one non-stop flight a day, is the only one of those airlines without connecting flights beyond Denver.
Denver is a hub for both United and Frontier and a "emphasis city" for Southwest.
