Airport Information & Terminals

SFO: San Francisco International Airport. SFO connects by BART to the city, while cabs or app rides are easier for Silicon Valley, family luggage or late arrivals. Fog and bridge traffic can affect plans.

STL: St. Louis airport. St. Louis 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.
