Our airport tip for catching a lift to your next gate at Charles de Gaulle? Take the LISA, the ideal way for frequent flyers to save time getting from terminal 2E to satellite S3. This automatic shuttle runs every 4 minutes and takes you directly to your gate in almost no time at all. Going to a terminal even further away? Take the CDGVAL, which serves the 3 terminals in 5 stations, including the RER and the TGV station.
