Southwest Airlines today started a new fare war with $29 one-way fares from Sea-Tac to Spokane and return. With taxes, that amounts to $39.50 each way.
Alaska Airlines and its Horizon Air sister airline have yet to match those fares, though they’ve initiated a $49.50 each way fare including taxes.
The Southwest fares must be purchased 21 days in advance. They’re good through Aug. 22, and not all flights offer seats at that low price.
If gas is $3.15 a gallon and your car averages 20 miles per gallon on the highway, gas costs for the 584-mile roundtrip to Spokane from Tacoma would cost $91.98 in gas and consume about nine hours driving time.
Flying time roundtrip would total about two hours plus about three hours of waiting time for a total of five and a half hours.
