Connecting the airport’s two terminals, the Aerotrén, which runs on elevated tracks, is the first such train in Latin America. It is speedy and efficient and provides an overview of airport activity—lively entertainment for restless kids. The Aerotrén operates from 5 a.m. to 11 p.m. Note: you must have a boarding pass to ride the train.
