Most visitors will only visit SeaTac for the Seattle-Tacoma International Airport , itself nicknamed Sea-Tac – the city named itself for the airport. Outside of the airport and its surrounding bevy of related businesses, including the corporate HQ of Alaska Airlines, there's little to attract tourists, although business travelers may appreciate the cluster of hotels close to the airport.
From I-5, take Exit 154B (SR-518) for the airport. The same interchange connects to I-405's southern end.
The region's sole light rail line terminates at the airport. SeaTac/Airport Station  also connects to a passenger pickup/dropoff just east of the airport, on the east side of International Boulevard at S. 176th St. The only parking at this station is in the airport parking garage. The line travels north through Tukwila to Seattle, reaching downtown in just over half an hour. The fare varies by distance traveled, topping out at $2.75.
Tukwila, immediately to the north, also hosts several hotels and offsite airport parking.
