IAH's primary departure runways (15L/R southbound or 27 westbound) mean a left-seat passenger looking east or north gets the Houston skyline and the ship channel industrial complex as the aircraft climbs and turns northeast toward Montreal. The downtown Houston cluster is clearly visible to the left as the plane banks north. Notable sights include: Houston downtown skyline, Houston Ship Channel and refinery complex, Lake Houston to the northeast, Buffalo Bayou corridor.

On a typical approach from the southwest on runway 24, the aircraft tracks northeast over the St. Lawrence River valley. Left-side passengers get the broad St. Lawrence River, the Montreal island, and Mount Royal's distinctive wooded hill rising above the city grid — the most visually striking feature of the approach. Notable sights include: St. Lawrence River, Mount Royal (233m wooded hill), Montreal downtown skyline, Île de Montréal urban grid.
