Route notes
Why this routing works
This 5-week economy route departs Saint Louis for Paris, then continues through Basel, Amsterdam, London, and Dublin before returning to Saint Louis. The stop order keeps the trip moving in a clear sequence across Western Europe, with longer stays in Paris, London, and Dublin and shorter intervals in Basel and Amsterdam.
At 9 nights in Paris, 5 in Basel, 3 in Amsterdam, 10 in London, and 7 in Dublin, the timing balances major gateways with shorter connecting stops. That mix can work well for travelers who want a multi-city ticket with defined pacing rather than a faster loop with many one- or two-night stays.
From a ticketing standpoint, this is a classic open-jaw-style multi-stop structure built as one continuous itinerary rather than separate round-trips. Starting with the transatlantic flight into Paris and finishing from Dublin back to Saint Louis reduces backtracking and keeps the final leg positioned on the western edge of the route.
With a July departure in the Jul-Sep season and a sold price range of USD 2,135 to 3,257 in economy, this itinerary fits a peak-season transatlantic travel window. The route covers five European cities in five weeks while maintaining a simple outbound-across-Europe-then-home structure.
