Airport Information & Terminals
SEA: Seattle-Tacoma International Airport. Sea-Tac connects to downtown by light rail, while cabs are useful for Bellevue, Redmond or late-night arrivals. Rain and freeway traffic should be part of the plan.
BIL: Billings airport. Billings airport transfer should be matched to the exact hotel, suburb or meeting area. Rail can work well for light luggage, but late arrivals, winter weather and family baggage often make a direct cab or booked transfer easier.
