Our guide explains how the YUL-CDG route appears on a tracker map.

Can the Boeing 777-200ER comfortably fly AF343?

Not at all. At roughly 42% of its range, this is an easy trip for a Boeing 777-200ER. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Boeing 777-200ER.

What to know about AF343

  • Time change: you land 5 hours ahead of the time you left. That is enough to cause jet lag. Here is how pilots handle it.

What we know about AF343

What flying YUL to CDG takes

It is a long-haul sector, a widebody route with a full night's flying time. Air France needs a widebody twinjet: the sector needs long-range tanks and a cabin crew rest provision, which rules out most single-aisle types. Eastbound, the jet stream is usually a tailwind, so the return leg against it tends to be the longer of the two. In daylight the sun sits on the right (south-facing) side of the cabin for most of the crossing.

How we verified this

The origin and destination on this page are the ones we verified for callsign AFR343 through adsbdb, not a schedule copied from elsewhere. We have logged it airborne on 37 days between 2026-09-19 and 2026-10-25. Timings are observations, not an official operational status: always confirm with the airline before travelling.

This page was published from our own tracking record rather than a third-party schedule feed, so it grows as we see the flight again. The seven-day log below is the raw version of the same evidence.

AF343 against the rest of the YUL-CDG pairing

We track 2 scheduled services between Montreal and Paris, split between Air Canada and Air France. Among them, it is the only one flown with a Boeing 777-200ER.

Measured against AF343:

Block time is gate to gate, so it counts taxi at both ends. That is why two flights covering identical distance rarely share a scheduled duration.

AF343 activity in the past 7 days

Our database contains 4 observations of AF343 across 4 UTC dates in this window, most recently 2026-10-25. Those records contain 3 distinct transponder addresses. The most frequently resolved route was YUL-CDG (4 records).

The median recorded visibility was 1252 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does AF343 emit?

Worked from the great-circle distance and the fuel burn measured for Boeing 777-200ER, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown5,524 km
AircraftBoeing 777-200ER
Fuel burn rate6.96 kg per km
Fuel burned38,442 kg
CO2, whole flight121.5 tonnes
Seats, typical layout301
Passengers carried250 at an 83% load factor
CO2 per passenger486 kg

Where that lands by cabin

The aircraft burns the same fuel whoever is aboard, so the cabins divide one total rather than each carrying their own. A seat's share is the floor it takes up, which is why an economy seat comes out below the 486 kg cabin average and a flat bed well above it.

Economy247 seats, 205 flown
357 kg CO2 per seat
Business45 seats, 37 flown
1,035 kg CO2 per seat
First9 seats, 7 flown
1,428 kg CO2 per seat

Taken whole, AF343 emits what 2,025 trees take back out of the air in a year. One economy seat on it accounts for about the same carbon dioxide as driving a petrol car 2,858 km, or 13,883 km of the same journey by train.

How this is worked out. Fuel burn is read from published measurements of this type, taken at sectors of 5,556 km, 10,251 km and 11,112 km, all longer than this route, so the closest is held flat and the real figure is likely a little higher. It counts carbon dioxide only, and the cabin split assumes the layout typical of this size of aircraft. Read the full method, sources and caveats, or put AF343 against another flight.

The route and typical schedule are maintained reference data. Live ADS-B observations are evidence of receiver coverage, not proof of on-time performance. Always confirm the operating date and times with the airline.
