6E31 route overview: DEL to SIN

6E31 distance and great-circle path

6E31 covers 4,158 km, or 2,583 miles. That makes it a long-haul flight, a widebody route with a full night's flying time. Of the 439 routes we track, it ranks 245 by distance.

The plane leaves New Delhi heading south-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 DEL-SIN route appears on a tracker map.

Why 6E31 block time differs from cruise time

The schedule allows 5.8 hours from gate to gate. That works out to about 723 km/h. An Airbus A321neo 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 Airbus A321neo comfortably fly 6E31?

Not really. It uses about 56% of the Airbus A321neo's range. That leaves room for a full load of passengers and bags. The full numbers are on our aircraft page for the Airbus A321neo.

How much CO2 does 6E31 emit?

Worked from the great-circle distance and the fuel burn measured for Airbus A321neo, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown4,158 km
AircraftAirbus A321neo
Fuel burn rate3.3 kg per km
Fuel burned13,717 kg
CO2, whole flight43.3 tonnes
Seats, typical layout180
Passengers carried149 at an 83% load factor
CO2 per passenger291 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 291 kg cabin average and a flat bed well above it.

Economy158 seats, 131 flown
237 kg CO2 per seat
Business22 seats, 18 flown
686 kg CO2 per seat

Taken whole, 6E31 emits what 722 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 1,711 km, or 8,312 km of the same journey by train.

How this is worked out. Fuel burn is read from published measurements of this type, taken at a 1,222 km sector, the only published sector for this type, applied to this route's 4,158 km unadjusted. 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 6E31 against another flight.
