I am arriving into Athens at 8.30am from Singapore Airlines, and connecting to 10.30am flight, Aegean Airlines towards Santorini. I am doing my own flight connection, so I need to check out of the immigration areas and check-in again. Will 2 hours be sufficient? How is the passenger immigration flow like in Athens airport? Are the counters easy to find?
Thanks a lot. It's my first trip to Greece.
