Sit on the Left side of the plane for the best views on flights from Montreal to New York. While takeoff favors the right for mountain views, the landing experience on the left—with Manhattan's iconic skyline and the East River—is more visually distinctive and memorable. The approach into LGA offers superior urban geography views that outweigh the takeoff advantage.

During takeoff from Montreal International Mirabel (YMX), sit on the Right side for the best views. Mirabel typically departs eastbound (Runways 22L/22R). Right-side seats face north initially, giving views of the Laurentian Mountains and the Ottawa River valley. Left side faces the flat terrain south of the airport with fewer distinctive features. Notable sights include: Laurentian Mountains (north, receding to horizon), Ottawa River (visible as a dark ribbon threading through forested terrain to the northwest), Gatineau Hills (distant, across the river to the north), suburban sprawl of Greater Montreal (south and east, diminishing with altitude).

When landing at La Guardia (LGA), sit on the Left side for the best views. Approaching LGA typically uses Runway 4 (northeast heading) or Runway 13 (southeast heading). Left-side seats on descent into LGA offer views of the East River, Manhattan's skyline, and the Bronx. Right side faces Queens and less dramatic urban features. Notable sights include: East River (dark water body separating Manhattan from Queens/Bronx, clearly visible), Manhattan skyline (dense cluster of tall buildings on the left, recognizable by height and density), Bronx (urban grid visible north of the river), Flushing Bay and LaGuardia Airport itself (visible in final approach).

The flight from Montreal International Mirabel (YMX) to La Guardia (LGA) takes Approximately 1 hour 15 minutes.

The flight path crosses the Hudson River valley, passes over the Catskill Mountains (visible as a distant ridge to the south during cruise), and follows the Hudson River southbound. The Appalachian foothills dominate the terrain beneath cruise altitude. Notable water features include the Hudson River itself (visible as a dark ribbon on clear days), and various reservoirs in upstate New York. The landscape transitions from boreal forest north of the Mohawk River to mixed deciduous forest and increasingly dense suburban development as the aircraft approaches the New York metropolitan area.
