Airport Information & Terminals
ATL: Hartsfield-Jackson Atlanta International Airport. Atlanta airport is one of the world's busiest, so connection time and terminal movement matter. MARTA is useful for downtown and Midtown; cabs are better for suburbs or heavy luggage.
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.
