To find cheap flights from Athens Eleftherios Venizelos Airport (ATH) to Tampa International Airport (TPA) in October, start searching 6–10 weeks before your travel dates and use flexible-date calendars. Mid-week departures (Tuesday–Thursday) and red-eye transatlantic legs often lower fares. Consider one-stop itineraries via major European hubs (London, Frankfurt, Amsterdam, Istanbul) or U.S. gateways (New York, Atlanta) — sometimes splitting your trip (ATH to a European hub separately, then hub to TPA) can save money. Set price alerts, clear cookies or use incognito mode for unbiased pricing, and check airline sales from Aegean, British Airways, Lufthansa, Delta, and American for October promotions. Book refundable or changeable economy fares if prices are volatile due to late-season weather.
