Route notes
Why this routing works
This routing uses an open-jaw structure to keep the trip moving in one direction across Europe. It starts with the long-haul from New York City to Poznan, allows 9 nights on the ground there, then switches to an overland segment into Milan before a final intra-Europe flight to Geneva and the return across the Atlantic to New York City.
The overland break between Poznan and Milan is the key planning feature here. Instead of forcing a backtrack by air, the ticket separates those cities and resumes in Italy, which can make a short multi-country trip easier to sequence within a 3-week window.
In economy, this is a straightforward multi-stop setup with one transatlantic outbound, one transatlantic return, and a single flight inside Europe after the overland portion. With departure in June and a sold price range of $1,189 to $1,813, this is the kind of itinerary where the order of cities matters as much as the fare, since the ticket is built around surface travel in the middle rather than round-trip logic.
