Stansted is to be linked to India for the first time next month with the start of flights to Amritsar.
Air India is to run three flights a week to the city in the north-west of the country.
The Boeing 787 Dreamliner service starts on October 31 offering a two-class configuration.
Airport CEO Ken O’Toole said: “Stansted is ideally situated to serve the Asian community in north and east London and across the East of England so we are delighted that Air India has recognised the customer demand for Amritsar.
“Just last week, we published our ‘Gateway to Growth’ report that highlighted the strong and growing demand for long-haul services across the region.
“Our ambition is to use our spare runway capacity to build our long-haul route network and improve the UK’s connectivity with the rest of the world at a time when availability is in short supply across south-east airports.
“The welcome arrival of Air India is another positive step towards that goal.
“India is an important and popular destination for UK residents, both for tourism and business interests. We look forward to working with Air India to make this route a great success and further improving the connectivity between London and India in the coming years.”
