WINTER BY AIR
When October ends so do all the cheap charter flights. The only flight into Zakynthos is the daily domestic flight to Athens run by Olympic Airlines. This flight to Athens can be as expensive or more than the flight to UK.
WINTER BY BOAT
Ferries run all year although they will have a reduced service. Weather conditions can also be a major factor in the local time table. The ferries between Kilini and Zante are not bookable very much in advance. You buy your ticket when you reach port or you can get it a day or two before.
