Sit on the Left side of the plane for the best views on flights from Dallas-fort Worth to Montreal. The left side wins overall because the Montreal arrival view — St. Lawrence River, Mount Royal, and the island city layout — is more visually dramatic and geographically distinctive than the DFW departure. En route, the left side also picks up better views of the Mississippi River crossing over Arkansas/Tennessee and the Great Lakes shoreline approaching Quebec.

During takeoff from Dallas Fort Worth International (DFW), sit on the Right side for the best views. DFW's primary departure runways (17C/17R heading south, or 18L/18R) often swing aircraft northeast toward Dallas. On a northeastbound departure to Montreal, the right side gives you the Dallas-Fort Worth metroplex spread across the horizon, including downtown Dallas skyline and the Trinity River corridor. Left side faces west toward open scrubland with little of interest. Notable sights include: Downtown Dallas skyline, Trinity River floodplain, Lake Ray Hubbard to the east, Fort Worth urban grid to the west briefly visible.

When landing at Montreal International Dorval (YUL), sit on the Left side for the best views. Montreal's Dorval airport typically uses runways 24L/24R (heading west) or 06R/06L (heading east) for arrivals. On an approach from the southwest, the left side gives you the St. Lawrence River, the Island of Montreal, and the city's urban core including Mount Royal. The right side faces north toward the flat Laurentian lowlands. Notable sights include: St. Lawrence River, Island of Montreal, Mount Royal (233m hill visible as a forested dome), Old Montreal waterfront district.

The flight from Dallas Fort Worth International (DFW) to Montreal International Dorval (YUL) takes Approximately 3 hours 30 minutes to 3 hours 50 minutes.

The route tracks northeast over Arkansas, crossing the Mississippi River near Memphis (a wide braided river visible from altitude), then over Tennessee and Kentucky. Continuing northeast over Ohio and Pennsylvania, the southern shore of Lake Erie may be visible on the left. Crossing into upstate New York, the Adirondack Mountains appear as a wrinkled dark forested plateau before descending into the St. Lawrence lowlands approaching Montreal.
