Route notes
Why this routing works
This five-week economy itinerary is built as a westbound loop from Lisbon through the United States, down to Mexico City, and back across the Atlantic via London. The sequence keeps the shortest stop first, with a one-night break in Dallas before continuing to Los Angeles for four nights.
From Los Angeles, the routing turns south to Mexico City for the longest stop outside Europe at 12 nights. It then uses a single long-haul move back to Europe, where London carries the final extended stay at 18 nights before the last leg returns to Lisbon.
As ticketing goes, this is a straightforward multi-stop structure with all sectors flown and no surface gaps. The pacing separates the transatlantic crossings, placing the westbound crossing at the start and the eastbound return later in the trip after the North American stops are complete.
