Sit on the Right side of the plane for the best views on flights from Montreal to Lisbon. Right seats capture the departure over the St. Lawrence and Laurentians, then offer views of Greenland's ice sheet and the North Atlantic during the transatlantic crossing. While the landing favors left, the 6+ hour flight duration means the right side provides more compelling scenery for the majority of the journey.

During takeoff from St Hubert (YHU), sit on the Right side for the best views. St-Hubert typically departs eastbound (Runway 06/24 favors east). Right-side seats offer views of the St. Lawrence River valley and the Laurentian Mountains receding eastward, plus the urban sprawl of greater Montreal to the north. Notable sights include: St. Lawrence River (immediate south), Laurentian Mountains (northeast horizon), Montreal urban area (north), Île Perrot (west, visible on climb-out).

When landing at Lisboa (LIS), sit on the Left side for the best views. Lisbon typically lands westbound (Runway 03/21 favors west approach). Left-side seats provide excellent views of the Tagus River estuary, the city's historic districts on the north bank, and the bridge approaches during descent into Humberto Delgado Airport. Notable sights include: Tagus River estuary (dominant feature), 25 de Abril Bridge (suspension bridge visible on approach), Lisbon city center and Alfama district (north bank), Cristo Rei monument (south bank, Almada).

The flight from St Hubert (YHU) to Lisboa (LIS) takes Approximately 6 hours 45 minutes.

Greenland's ice sheet (visible during mid-Atlantic crossing at cruise altitude—the massive white expanse of the Greenland Ice Sheet dominates the view if flying the northern great-circle route), the North Atlantic with occasional icebergs visible in spring/early summer, the Irish coast (County Kerry and Dingle Peninsula) as you approach European airspace, and the Bay of Biscay before descent into Portugal.
