August is prime beach and festival season in Greece, making it an excellent time for warm-weather travel but also the most expensive and crowded. If your priority is warm sea temperatures and nightlife, August is ideal; however, for lower fares, fewer crowds, and milder weather, consider May–June or September–October.

Use the primary search phrase 'cheap flights from Chicago O'Hare (ORD) to Athens International Airport (ATH) in August' when checking deals and compare shoulder season alternatives.
Nonstop flights (if available in August) offer the fastest travel time—usually under 10.5 hours—but tend to be more expensive and can sell out early. One-stop itineraries through European hubs like London, Frankfurt, or Amsterdam often cost less and offer more schedule flexibility but add 2–6+ hours of travel time including layovers. For travelers prioritizing comfort and speed, book nonstop; for budget-conscious travelers, choose a single connection with a sensible layover and check baggage-through and transfer times. When searching, include the phrase 'direct flights from Chicago O'Hare (ORD) to Athens (ATH)' to find nonstop options and compare with one-stop routings.
