Rome's Fiumicino airport, known officially as Leonardo da Vinci, has three new direct high-speed connections with Naples and Florence as part of a major development to link rail and air travel for its passengers.

The new Frecciarossa services comprise two running to and from Napoli Centrale and Napoli Afragola and one departing from S. Maria Novella in Florence, Rome's airport management company Aeroporti di Roma (AdR) said in a statement.
