CA125 route overview: PEK to ICN

CA125 distance and great-circle path

CA125 covers 901 km, or 560 miles. That makes it a short-haul flight, a single-aisle hop where turnaround time matters more than range. Of the 439 routes we track, it ranks 390 by distance.

The plane leaves Beijing heading 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 PEK-ICN route appears on a tracker map.

Why CA125 block time differs from cruise time

The schedule allows 3.8 hours from gate to gate. That works out to about 240 km/h. An Airbus A330-300 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 what really moves flight times.

Can the Airbus A330-300 comfortably fly CA125?

Not at all. At roughly 8% of its range, this is an easy trip for an Airbus A330-300. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Airbus A330-300.

What to know about CA125

  • Time change: you land 1 hour ahead of the time you left.

CA125 activity in the past 7 days

Our database contains 8 observations of CA125 across 8 UTC dates in this window, most recently 2026-10-29. Those records contain 6 distinct transponder addresses. The most frequently resolved route was PEK-ICN (8 records).

The median recorded visibility was 80 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does CA125 emit?

Worked from the great-circle distance and the fuel burn measured for Airbus A330-300, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown901 km
AircraftAirbus A330-300
Fuel burn rate6.25 kg per km
Fuel burned5,628 kg
CO2, whole flight17.8 tonnes
Seats, typical layout277
Passengers carried230 at an 83% load factor
CO2 per passenger77 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 77 kg cabin average and a flat bed well above it.

Economy227 seats, 188 flown
56 kg CO2 per seat
Business42 seats, 35 flown
162 kg CO2 per seat
First8 seats, 7 flown
224 kg CO2 per seat

Taken whole, CA125 emits what 296 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 455 km, or 2,209 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 and 10,275 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 CA125 against another flight.
