Airport Information & Terminals

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.

YYZ: Toronto Pearson International Airport. Pearson sits outside downtown. UP Express is often the fastest way to Union Station; cabs or app rides are better for suburbs, families, students with bags or late arrivals.
