The closest commercial airport is Marco Polo Airport (IATA: VCE), on the mainland near Mestre (technically part of the city of Venice but on the mainland and without Venice’s unique structure). There is a city bus and a shuttle bus from Marco Polo to Piazzale Roma. See the details in the “By bus” section below.
Treviso Airport (IATA: TSF) is 25km (16 mi) from Venice and is relatively small but becoming increasingly busy as the main destination for Ryanair, Wizzair, and Transavia budget flights. From Treviso Airport to Venice and Mestre, Barzi Bus Service offers a €22 (Oct 2016) round-trip ticket price to Venice. These tickets are also available on their bus.
The San Nicolo Airport (IATA: ATC) is an airfield directly on the Lido. It handles only small aircraft, as the runway is grass and only about 1km long. It does not have any scheduled flights, but might be of interest to private pilots (arrivals from Schengen states only) due to its convenience to the city; it is only a short walk to the vaporetto landing.
From the airport to the city centre
The airport is connected to the railway station of Mestre, opposite the city and convenient for connections to Milan, Padova, Trieste, Verona and the rest of Italy); to the railway station of Venice (5 minutes’ walk from Piazzale Roma); and to the bus terminal of Piazzale Roma in Venice by scheduled bus services. You can take a bus, a taxi or a water taxi.
Water taxi is also the most comfortable (and expensive) way to arrive directly to your hotel in Venice, to Venice Cruise Port terminal and to Lido di Venezia (a big island in front of Venice).
Water taxi departures are 10-15 minutes’ walk from the Marco Polo airport. From the arrivals hall exit, turn to your left through the airport grounds to the boat departure point. Here you will find free trolleys to carry luggage for the short trip to the water taxi departure point. There are also some companies that offer porter services and/or private minivan transfer from the airport to the water taxi departure point.
Depending on the kind of service requested (meet & greet, luggage assistance, minivan transfer or simply water taxi) the price can run from €100 to €160 (4 people with luggage) from Marco Polo Airport to Venice City Centre or to the Cruise Port Terminal. Every additional passenger costs €10-20. A maximum of 10 people can take one standard water taxi.
The price for a shared transfer will be €35 per passenger, but in this case you will have to wait for other passengers until the water taxi will be full.
When you exit the airport, the ACTV bus #5 will be on your left and the ATVO bus will be on your right; both will take you to Piazzale Roma (the only part of the city of Venice that you will be able to reach with ground transportation).
ATVO (provincial company) buses and ACTV (city company) buses (route 5 aerobus) leave for Venice (Piazzale Roma). When you exit the airport, the ACTV bus #5 will be on your left and ATVO bus will be on your right.
