Direct vs Connecting Flights — SAT to ATH Recommendations for September Travel
Since there are no nonstop options between San Antonio International Airport (SAT) and Athens Eleftherios Venizelos International Airport (ATH), you must choose between one-stop and two-stop itineraries.

Two-stop itineraries can be cheaper and allow flexible scheduling (e.g., overnight in a hub city) but increase the probability of missed connections. In September, aim for 90–180 minute international layovers to clear immigration and baggage re-check; prioritize itineraries on a single carrier or alliance to improve rebooking protections.
