TK1979 route overview: IST to LHR

TK1979 distance and great-circle path

TK1979 covers 2,488 km, or 1,546 miles. That makes it a medium-haul flight, long enough for a full meal service, short enough for narrowbodies. Of the 439 routes we track, it ranks 297 by distance.

The plane leaves Istanbul heading north-west. 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 IST-LHR route appears on a tracker map.

Why TK1979 block time differs from cruise time

The schedule allows 4.1 hours from gate to gate. That works out to about 609 km/h. An Airbus A350-900 cruises faster than that. The gap is taxi time, climbing, descending and holding.

Flying west, this route pushes against the wind. The trip back east is usually shorter, even though the distance is the same. See what really moves flight times.

Can the Airbus A350-900 comfortably fly TK1979?

Not at all. At roughly 17% of its range, this is an easy trip for an Airbus A350-900. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Airbus A350-900.

How much CO2 does TK1979 emit?

Worked from the great-circle distance and the fuel burn measured for Airbus A350-900, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown2,488 km
AircraftAirbus A350-900
Fuel burn rate6.03 kg per km
Fuel burned15,003 kg
CO2, whole flight47.4 tonnes
Seats, typical layout300
Passengers carried249 at an 83% load factor
CO2 per passenger190 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 190 kg cabin average and a flat bed well above it.

Economy246 seats, 204 flown
140 kg CO2 per seat
Business45 seats, 37 flown
405 kg CO2 per seat
First9 seats, 7 flown
559 kg CO2 per seat

Taken whole, TK1979 emits what 790 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 1,120 km, or 5,440 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 9,208 km, 10,249 km and 12,116 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 TK1979 against another flight.
