Best side of the plane YUL to CDG
Montréal to Paris. The better window changes with your date and departure time, because the sun moves and the approach into Paris depends on the runway in use. Run your own date for the real answer.
Which side today? →What decides it on this route
Three things: where the sun sits relative to your heading, which side Paris passes on during descent, and what scenery the track crosses — coastline, mountains, lakes or islands.
Sunset and sunrise
Sun position is calculated exactly for your departure time, so this is the most reliable part of the answer. An evening departure and a morning departure on the same route often favour opposite windows.
City views into Paris
The last fifteen to thirty minutes matter most. We estimate the likely runway from wind and runway geometry, then place Paris relative to that path — and lower the confidence because air traffic control can change runways.
