Route notes
Why this routing works
This itinerary is structured as a compact 2-week North America loop from Berlin, starting with short stays in New York City, Montreal, and Toronto before an open-jaw break between Toronto and Houston. That overland segment gives the ticket flexibility without forcing a backtrack, then resumes with flights from Houston to Seattle, on to San Diego, and back to Berlin.
The sequencing keeps the trip moving generally east to west across North America after the Atlantic crossing. With only 2 nights in New York City and 1 night each in Montreal, Toronto, and San Diego, this works best as a fast-paced multi-stop plan where the flight order matters as much as the stop list.
Because Houston is reached overland, this is not a fully air-only chain; it is a mixed routing that can suit travelers who want to handle one section independently. On the ticketing side, that open-jaw structure can be a practical way to connect multiple cities without requiring a same-city continuation between Toronto and Houston.
In economy class, the sold range of USD 1,164 to 1,775 places this as a relatively accessible multi-stop itinerary for a September departure in the Jul-Sep season. The route is best understood as a logistics-first plan: transatlantic entry into the U.S., short hops through eastern Canada, an overland gap, then a westward continuation across the U.S. before returning to Berlin.
