Route notes
Why this routing works
This four-week itinerary uses an open-jaw start in Europe, with Barcelona listed as an overland arrival rather than a flown segment on the ticket. That structure can be useful when one stop is brief, as it keeps the long-haul pricing anchored on Boston while leaving flexibility for how you reach the first European city.
After the Barcelona arrival, the ticket resumes with onward flights to Lisbon, then Marrakech, then London, before the final transatlantic return to Boston. The sequencing is straightforward for a multi-stop Atlantic trip: a short stop, a longer base in Lisbon, a one-week North Africa segment, and a final European stop before flying home.
With 15 nights in Lisbon, 7 in Marrakech, and 5 in London, most of the trip time is concentrated in the middle and back end of the route rather than spread evenly across every stop. In economy, that balance works well for travelers who want a simpler ticket with a limited number of flight legs and only one overland break built into the plan.
For timing, a May departure in the April-to-June season places the route in a common shoulder-period window for transatlantic and intra-regional travel. Based on the sold itinerary data, this routing was priced from USD 1,361 to USD 1,782 in economy.
