AC870 distance and great-circle path
AC870 covers 5,524 km, or 3,432 miles. That makes it a long-haul flight, a widebody route with a full night's flying time. Of the 255 routes we track, it ranks 155 by distance.
The plane leaves Montreal heading north-east. On the map above, the line looks curved. That is normal. The shortest path over a round planet never looks straight on a flat screen. Our guide explains how the YUL–CDG route appears on a tracker map.
Why AC870 block time differs from cruise time
The schedule allows 7.1 hours from gate to gate. That works out to about 780 km/h. A Boeing 777-300ER cruises faster than that. The gap is taxi time, climbing, descending and holding.
Flying east, this route usually picks up tailwinds high up. The flight back west normally takes longer, even though the distance is identical. See how timing changes the trip in our red-eye flight guide.
Can the Boeing 777-300ER comfortably fly AC870?
Not at all. At roughly 40% of its range, this is an easy trip for a Boeing 777-300ER. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Boeing 777-300ER.
What to know about AC870
- Time change: you land 6 hours ahead of the time you left. That is enough to cause jet lag. Here is how pilots handle it.
