I am traveling to Greece in June 2022 and need advice on how much time to give myself during a layover in Athens when switching airlines!
I will be flying from Atlanta, USA on Delta Airlines and will land in Athens at 11:20AM. I would then like to fly into Santorini from Athens. I was planning on buying a seperate ticket from Athens to Santorini through a European airline like Volotea or Sky Express (Delta does not even offer an itinerary from Atlanta to Santorini so I actually have to do this).
I am wondering.... when I deplane in Athens, can I just stay in the Athens airport and go to the gate for my other airline and fly to Santorini, and do passport control/immigration at the Santorini airport (I figure if I can do that, the normal 1.5 hour layover is fine)? Or will I have to deplane in Athens, go through passport control in Athens, re-enter international security, and then fly to Santorini? If that's the case - I would guess I need something more like a 2.5 or 3 hour layover.
We only have carry on bags so don't have to check luggage.
Thanks in advance!
