Anticipate needing extra time for Domestic check-i
Cons: If you arrive in Athens on an international flight and are heading to Santorini, you must collect your bags, proceed through customs and then journey to a different area of the airport for domestic check-in. . Hahn's service was exceptionally slow, with only one window. if possible pay for your bags online. I wasn't able to find the option to do so. Airport fee to check 2 average size bags was 70 euro and required us to wait in another line just to make the payment. We gave ourselves 2.5 hours between flights and barely made the boarding for Santorini. Flight is approx 35 minutes. Service was good and seats were comfortable.
