There will be 1.5 hrs. from the time I land at the Athens Airport by the international flight till I catch the next domestic flight from Athens to Santorini. Do both the international and the domestic flights depart at the same airport building or just next to each other ? I want to know if 1.5 hrs. is sufficient for me to change to the domestic flight. You know, I don't want to miss my next flight since it fits my travel plan nicely. Any view is welcome ! Thanks !
