Treviso airport is a small airport, smaller than the Venice airport, and it’s used mostly by the domestic and european flight companies like Ryanair…
You can catch here one of the frequent flights from/to Stansted UK and many italian cities.
The airport is at about 35/40 minutes drive from piazzale Roma or cruise port and, as the Venice airport, open the check in desks a bit less than 2 hrs before the flight departure.
