Is there a nonstop from Seattle (SEA) to Montreal (YUL)?
No airline currently schedules a nonstop from Seattle (SEA) to Montreal (YUL). Our records hold a single departure on this pair, in October 2026, operated by Sun Country, and no other in any month we have sampled. That is the pattern of a charter, a weather diversion or an aircraft being repositioned, not of a route you can book.
If an airline launches scheduled service here it will appear on this page once we have seen it fly in two separate months. In the meantime, Seattle–Tacoma International Airport flies nonstop to 129 destinations.
Based on observed departures through October 2026. Airlines add and drop routes continually — confirm with the airline before you plan around this.
