Myself and some friends arrive at Santorini airport at 1.10 pm on the 24th of July. I see the latest ferry to Ios on the schedules is currently listed at 2.30 pm on the same day. My question is, as this doesn't allow for much of a delay, how likely is it that another later ferry is added to the schedule? Obviously a later ferry would be a lot less stressful in case of a flight delay. Do you think it's possible to make this ferry if we had pre purchased our tickets?
