M going to greece at end of sept. For ten days Want to go to santorini and mykonos for sure do i need to book my airline ahead of time to islands or just buy them same day? I worry that our flt from jfk could get us tgere late so could just purchase same days we go and leave islands? My athens rt tickets already confirmed
There is both a risk of your flight to Athens arriving late and a risk of flights to the islands selling out. You can give yourself a cushion, either by planning a longer layover at Athens airport, or by staying a night or two in Athens itself. September is not as busy as August, but also not low season.
