Distance between London and Chennai

Driving non-stop from London to Chennai

How far is Chennai from London? Here's the quick answer if you have friends taking shifts as driver so that you can make the entire trip by car without stopping.

Nonstop drive: 6,819 miles or 10974 km

Driving time: 130 hours, 33 minutes

Flying non-stop from London to Chennai

Now let's assume you have a private jet and you can fly in the fastest possible straight line between London, United Kingdom and Chennai, India. Because of the curvature of the Earth, the shortest distance is actually the "great circle" distance, or "as the crow flies" which is calculated using an iterative Vincenty formula. For a long distance, this appears as a curve on the map, and this is often the route that commercial airlines will take so it's a good estimate of the frequent flyer miles you'll accumulate as well.

Flight distance: 5,106 miles or 8217 km

Flight time: 10 hours, 43 minutes

The straight line flight distance is 1,713 miles less than driving on roads, which means the driving distance is roughly 1.3x of the flight distance.

Your plane flies much faster than a car, so the flight time is about 1/12th of the time it would take to drive.

This is a fairly long flight, so unless you have a Gulfstream G650 or your own Boeing or Airbus, you might be booking a commercial flight. In that case, your travel time would really need to include how many minutes to get to your local airport, wait for security, board and taxi on the runway, land at the other airport, and get to your destination. Scroll down to see a more realistic calculation that takes into account all these factors to get a more accurate estimate of your actual flight time.

London to Chennai airports and flights

In the quick calculation above, we assumed you had a private plane and just wanted to know the time in the air from city to city. But for most of us, we're going to be flying on a commercial airline (whether it's first class or coach). So that means we really need to account for all the extra travel time getting to the airport, waiting for our flight, and making it to the destination.

To give you a better estimate of real-life travel, we've put together a flight itinerary with actual airports. Eventually you'll be able to customize this plan, choosing your own airports and flights. But for now, here's an example we've selected to give you an idea of how traveling might work between airports.

Departure airport: London Heathrow Airport (LHR)

Arrival airport: Chennai International Airport (MAA)

With the airports selected, we can estimate the travel time to and from the airport, based on how far the airport is from downtown.

Getting to the airport: 44 minutes

Getting to your destination: 32 minutes

Now finally, let's look at an actual flight from LHR to MAA on British Airways and figure out how long it would take to fly including take-off and landing, and time to taxi on the runway.

Commercial flight time: 10 hours, 43 minutes

So now we can finally get an idea of the total travel time from London to Chennai including time spent getting to/from the airports, an estimated wait time of 2 hours at the airport for TSA security lines and waiting at the gate, and the actual flight itself.

Total travel time: 14 hours
