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 255 routes we track, it ranks 174 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 70% 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.
