This subject came up little while ago, but I can't find the earlier postings at the moment.
I found the website at www.airsealines.com/ Hope this helps.
Once operating, particularly if the aircraft operate out of the Brindisi/Bari area, this might provide a cheaper alternative to the current routes into the Ionian if traveling independantly. The unfortunatle thing about the Easyjet flight to Athens is that it doesn't readily tie up with the Olympic flight to Corfu in terms of timing and the inter island flight can be expensive for a 45 minute flight! This is particularly so when you consider that the extension is only about £20 if flying Olympic from Heathrow - and you can check your bags all the way through without having to go through reclaim at Athens.
I haven't looked for any schedules for the seaplanes yet, but the operational restrictions in bad weather might make the service a little unpredictable during the winter months.
