I am going to Greece with 3 of my girlfriends in late August/early September and our first stop is Santorini. We want to get an Aegean flight out to Santorini on the same day we fly into Athens from the US. However, cost is an issue and there is only 1 flight left (at 5am) with the "economy" fare. Do they usually add more flights as it gets closer to the summer? Or is this it?
