Just having a nosey at the bus timetable from Corfu to Arillas and Mon-Fri there are two buses one that leaves Corfu at 5am and one at 2pm. Says the journey takes an hour and a half but at a little over 4 euros yes that's FOUR euros a significant saving on the taxi price of usually 57-58 euros as well as a little adventure ! There are a few more options going back to corfu
There's the new bus station now open near the airport as well, Jo. A bit of a trek but definitely within walking distance. Apparently there is also a shuttle bus from the airport to the bus station but I don't know how dependable it is.
Enjoy.

Have used the bus several times both ways and you get a great tour of the north east. There is a new bus station which as above is close to the airport and town. There is a brand new web site with maps and timetables - just google Corfu green buses.
