I've just checked back at last year's schedule and it looks as though Flying Cat 4 made its first journey from Santorini to Mykonos on 6th April although that was on a Friday, but its next journey wasn't until the following Friday. However, I think that was just before Greek Easter which isn't until May this year. So this may be a possibility but until their schedule is published we won't know what date they are starting this year.

The provisional Flying Cat 4 schedule for the first few weeks of the seaon is now on GTP and Hellenic's web site - it doesn't start until April 27th this year.

That continues the usual pattern of FlyingCat 4 starting its season the weekend before Greek Easter.

Thanks Mikets. I hadn't realised that schedule was there yet. There's some odities like the Highspeed 5 finishing its morning journey in Tinos then starting its evening return journey in Mykonos :-), and Flying Cat 4 returning from Mykonos to Ios then Paros :-)
