Seattle–Tacoma International Airport (SEA), often called Sea-Tac, is the city’s main international and connecting hub serving legacy carriers and many full-service international routes, while also hosting several low-cost domestic airlines. It sits about 14 miles south of downtown Seattle; travel time to the city center is typically 20–45 minutes by Link light rail (about $3–4), airport shuttle or taxi (roughly $40–60), with ride-shares and buses offering variable fares. Sea-Tac is usually perceived as mid-range in price: cheaper than some transcontinental gateways but pricier than purely budget airports. Pros include frequent flight options and direct rail access; cons can be crowding during peak hours and occasional terminal congestion.
