Flying out of Washington Dulles
Washington Dulles is United's mid-Atlantic hub and the most convenient long-haul airport for the DMV's very large South Asian population across Fairfax, Loudoun and Montgomery counties. Dulles punches above its size on India routes specifically, and because BWI and Reagan National handle most of the region's domestic traffic, IAD's international schedule is unusually clean — fewer misconnects, and a realistic same-terminal connection where other hubs would need a terminal change.
What to know before you fly to Athens
Entry requirements for US travellers
US citizens can visit Greece and the wider Schengen Area without a visa for short stays. The EU's ETIAS travel authorisation is being phased in and will eventually apply — check whether it is in force for your dates on the EU's official ETIAS site rather than assuming either way, and note that Schengen days are counted across the whole area, not per country.
Best time to go
May, June, September and early October are the sweet spot: hot enough for the islands, cool enough for the Acropolis, and materially cheaper than July and August. High summer is genuinely crowded and expensive. Winter fares are the lowest of the year and Athens itself is a fine winter city, though most island service is seasonal and thins out sharply.
Airports and arrival
Athens Eleftherios Venizelos (ATH) is the country's main gateway and the hub for domestic connections to every island. The metro runs straight into Syntagma in about forty minutes. If you are island-hopping, ATH is where the ferry and the domestic flight networks meet.
Baggage
Most US–Athens itineraries connect through a European hub, and the second leg is frequently on a partner or low-cost carrier with tighter rules than the transatlantic one. Onward flights to the islands are stricter still. We confirm one allowance end to end rather than leaving you to discover the difference at a gate in Frankfurt.

Washington DC to Athens — frequently asked questions
Fares on the Washington DC–Athens route vary widely by season and how far ahead you book. We do not publish an estimate we have not measured for this pair; call our agents and they will quote the live consolidator fare for your dates.
Carriers on this route include Delta, United, American, Lufthansa, Air France–KLM, Emirates and Aegean Airlines. Others serve it on one-stop itineraries, and the cheapest is not always a name you would expect — the lowest fare we have tracked here was on a carrier outside that list more than once. Itineraries offer seasonal nonstops from the largest gateways, otherwise a single connection through a European hub, and total journey time runs about 10–16 hours. Which carrier is cheapest changes with the season and the fare bucket rather than staying fixed, which is why we compare them all on every quote.
Plan on 10–16 hours from Washington Dulles International (IAD) to Athens Eleftherios Venizelos International (ATH), including time on the ground if your itinerary connects.
Book four to six months ahead for June through September, when the island season and the transatlantic peak collide; six to ten weeks is enough for the shoulder months, and Greek Orthodox Easter — which usually falls on a different date to Western Easter — needs booking as early as high summer.
Yes — this route has nonstop service, with seasonal nonstops from the largest gateways, otherwise a single connection through a European hub. Nonstop is not always the cheapest option: a one-stop itinerary on the same dates is frequently a few hundred dollars less, and on a journey of 10–16 hours that trade is worth pricing rather than assuming. Frequencies change by season, so call us for what is actually flying on your dates.
The DMV has three airports and they divide cleanly: Dulles (IAD) has the long-haul network, Reagan National (DCA) is domestic and close-in, and BWI is largely low-cost. For an international trip IAD is almost always the answer, but if your itinerary connects through another US hub, a DCA or BWI first leg can be both cheaper and far easier to reach.
Yes, and for a specific reason: almost every US–Greece itinerary has a European connection and an onward island leg, and those three segments are frequently cheapest as separate fares that a booking site will never combine. An open-jaw — into Athens, out of Santorini or Thessaloniki — usually costs nothing extra and saves a backtrack. That is the kind of ticket that has to be built rather than searched. SkyKaro's agents are reachable 24/7, and nothing is charged until an agent has confirmed the itinerary and the price with you.
