Route notes
Why this routing works
This route is built as a simple transatlantic open-jaw: fly from San Francisco to London, continue overland from London, then pick up the flight sequence again in Edinburgh. That structure works well when you want flexibility between arrival and the next ticketed segment without forcing a backtrack.
From Edinburgh, the itinerary resumes with a short intra-regional flight to Belfast, followed by the long-haul return to San Francisco. With 3 weeks total and 6 nights listed in Belfast, the pacing leaves room to spread time across the UK portion while keeping the overall flight pattern straightforward.
In ticketing terms, this is a clean multi-stop economy fare with one overland sector built in rather than a fully flight-only circle. For a July departure, keeping the route to a small number of stops helps limit connection complexity while still covering multiple points on one ticket.
