IndiGo, India’s largest airline, on Sunday operated its inaugural non-stop flight between Mumbai and London Heathrow, marking a major milestone in the carrier’s global expansion strategy.

The daily service, operated with IndiGo’s Boeing 787-9 Dreamliner, features a dual-class configuration — standard Economy and IndiGoStretch, the airline’s customized business-class product.

Heathrow, one of the world’s busiest airports, is considered a key gateway for international airlines. IndiGo’s new route connects two of the world’s major financial hubs, strengthening ties between India and the United Kingdom. The airline said the service will cater to strong travel demand between the two countries for education, tourism, and family visits.

With this launch, Indian travelers will now have the option to fly with IndiGo to London and connect onward through the carrier’s codeshare partners. Similarly, travelers from London will gain direct access to IndiGo’s network of more than 90 destinations across India.

“We are delighted to announce the launch of direct connectivity between Mumbai and London — two vibrant, global financial hubs with deep cultural and economic ties,” said Pieter Elbers, IndiGo’s chief executive officer. “This route is not just a new destination for us; it’s a bridge between cultures, businesses, and families.”

Elbers added that the new service represents a defining moment in IndiGo’s journey toward becoming a truly global airline, reaffirming its commitment to connecting India to the world through “efficient, consistent, and reliable service.”

IndiGo said the new route aims to make travel between India and the U.K. more seamless, accessible, and affordable.
