We have a trip to Greece planned in September (6 nights Crete, 4 Santorini, 2 Athens). Our roundtrip flight from the US is booked, as well as out hotels & flight from Athens to Heraklion (I was able to get a 19 euro fare). I have been watching the flights from Santorini to Athens, hoping that the prices will go down, but they seem to be going in the wrong direction. The flight I want is currently 79 euro (it was 64 the other day). Should I wait to see if a saver fare shows up, or is this not likely to happen? How fast do these flights fill up? The date I'm looking at is September 23. Thanks for your help.
