JFK→Athens, Rome→JFK (open-jaw, May 6-21)
An open-jaw US-to-Europe ticket is the value play this week — JFK to Athens, Rome back to JFK, routing via Lufthansa/United or Delta/Air France. Saves the internal Athens-Rome flight ($150-200 if booked separately) and enables a proper two-country trip. Operating 14-21 day windows in May held at $489-549 round-trip per person when we sampled Tuesday through Thursday.
