Route notes
Why this routing works
This itinerary keeps the routing simple: Boston to Lisbon, onward to Malaga, then back to Boston. With 5 nights in Portugal followed by 28 nights in Spain, it is structured as a short first stop paired with a longer stay before the transatlantic return.
As a multi-stop ticket, this routing is built around a single Atlantic crossing in each direction while linking two European cities in sequence. That can be useful for locking in the full city order in one plan rather than arranging separate one-way tickets between North America and Europe.
The timing fits a 5-week trip departing in March, with the schedule weighted heavily toward Malaga. In business class, the fare range of $6,865 to $8,987 frames this as a premium but straightforward two-stop Europe itinerary with one intra-Europe connection built into the overall routing.
