If you come by train from anywhere but Venice island, you'd better get off at Mestre station and take the orange bus 15 (a city line which stops several times along the route: it takes about 30-40 minutes) or the ATVO blue coach (direct, about 20-30 minutes, but more expensive). If you are at the Venice rail station, walk or take a waterbus to Piazzale Roma and take bus 5 (every 15 minutes at rush hours: it takes 20 minutes) or the ATVO coach (about 15 minutes).

Be aware that most European cheap flights are to/from Venice Treviso Airport which is in the city of Treviso and you should allow at least an hour for travel between Venice Train Station (or Piazzale Roma buses) to the airport.
