Route notes
Why this routing works
This itinerary is a short North America multi-stop built around an open sequence from London to Montreal, onward to Chicago, and back to London. With 3 nights in Montreal and 2 nights in Chicago, the routing keeps the stop pattern compact and fits within a one-week trip window.
Using a single multi-stop ticket for this sequence can simplify pricing and ticket management compared with booking each long-haul segment separately. The order also avoids backtracking within North America, moving west from Montreal to Chicago before the transatlantic return to London.
November timing places the trip in the October to December travel season, which is useful when comparing date options across the whole routing rather than pricing each leg in isolation. In economy, the sold fare range for this itinerary was USD 3,884 to USD 5,085.
