In September I’m flying from Calgary through Toronto to Athens. 3 hours later I have an Aegean flight to Naxos. I’m carrying on from Calgary to Athens, but will need to check my bag from Athens to Naxos. I’m not sure how this works. Do I need to leave the international terminal and go to the Agean desk to check the bag, or can this be done on the airside?
Thanks for your help!
