Indian airline Vistara is to add a second route from London with the addition of flights to Mumbai from the new year.

The joint venture between Tata group and Singapore Airlines will run three departures a week from Heathrow starting on January 16.

The new service will complement a Delhi service and Heathrow as part of a ‘transport bubble’ bilateral agreement between India and the UK

The carrier will deploy a three-class Boeing 787-9 Dreamliner on the new route with economy return fares starting at £439.

Foreign Office travel advice for India states that a limited number of flights are operating under a bilateral agreement “but these are subject to strict eligibility criteria and details may change at short notice”.

Vistara said it will accept all eligible customers meeting visa/entry requirements in both the countries, as specified by respective government bodies.

The airline said it “strongly encourages” customers to fully understand travel guidelines before making bookings.

Cabin crew wear personal protective equipment (PPE) at all times and avoid all non-essential interaction with passengers.

Chief executive Leslie Thng said: “We are delighted at the very positive response to our service between Delhi and London Heathrow which has encouraged us to further strengthen the network by adding connectivity from Mumbai as we see considerable demand between the two countries, and remain optimistic about the future.

“Vistara is well-positioned with its brand new fleet, world-class cabin products, award-winning service, and more importantly, the trust of our customers.”
