Indian airline Vistara has completed its first flight between Delhi and Heathrow.

The airline, which is a joint venture of Tata group and Singapore Airlines, will fly three times a week between the cities, and is operating until October 24 under a bilateral agreement between the UK and Indian governments.

Leslie Thing, chief executive, said: “Though not regular scheduled flights, we are excited about starting operations to our first long-haul destination. This, in many ways, marks the beginning of a new phase of growth in the global skies for Vistara.

“This also gives us the opportunity to introduce India’s finest and only five-star airline to London.”

The FCO currently advises against non-essential travel to India, and travellers returning are required to self-isolate for 14 days under quarantine rules.

Entry to India is also subject to requirements, including a 14-day quarantine.

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

It added: “Vistara strongly encourages its customers to fully understand the relevant guidelines before making their bookings.”
