Route notes
Why this routing works
This is a short North Atlantic multi-stop built around two brief stays: one night in Toronto, then one night in Washington DC, before returning to Paris. With just one week total, the sequencing keeps the trip compact and limits backtracking by moving westbound across two North American points before the transatlantic return.
Ticketing is straightforward in structure: an open sequence of CDG-YYZ-IAD-CDG rather than separate round-trips. That matters on a short itinerary because it keeps the route tied together on one plan while covering two cities in two countries within a single ticket framework.
Timing is the key consideration here. With only one night in each stop, this routing works best when the goal is to connect two North American cities efficiently inside a one-week window, rather than build in longer stays. In economy, the price range on this sample itinerary was $884 to $1,348 for a September departure.
