Round trip

Southwest has Seattle down to $177 round trip, 52% below the usual price and just above the $144 floor we have ever recorded on this route. Seattle brings easy access to the San Juan Islands, Mount Rainier, and a serious food and coffee scene for a fraction of the normal fare. With one connection on a reputable carrier, this is about as easy a booking as they come.
