The carrier on Tuesday (19 November) set out its summer 2020 flying programme from Heathrow.
It includes a new weekly Friday flight to San Francisco, boosting the service to twice-daily.
Virgin will deploy its new Airbus A350 aircraft on the route from May 2020 which, when coupled with the new weekly flight, will increase capacity by 40,000 seats for the summer season.
It has also announced it will deploy the A350 on routes to Johannesburg, Los Angeles and Lagos.
From March, Virgin will operate a daily Heathrow-Johannesburg A350 service. In April, the A350 will fly daily to Los Angeles and daily to Lagos from August.
The aircraft features a redesigned upper cabin and “unique” new social space, says Virgin.
Meanwhile, a new second daily service to Delhi will get under way on 29 March 2020. It will depart Heathrow in the morning, complementing the airline’s existing evening departure.
Virgin has also re-timed its Heathrow-Mumbai flight to an evening departure to make it more convenient for business passengers.
Juha Jarvinen, Virgin Atlantic executive vice-president commercial, said: “Next year will mark 20 years since Virgin Atlantic started flying to Delhi, and the service continues to grow in popularity for both business and leisure travel.
“The second daily service from Heathrow is an excellent opportunity to meet customer demand on this route and, coupled with our new service to Mumbai, we’re able to offer even more choice and unrivalled Virgin Atlantic service to customers travelling between the UK and India.
Jarvinen added: “We’re delighted to announce our flying programme for our brand-new A350 aircraft, starting from next summer. We’re confident our customers will love to fly on this new aircraft and will enjoy the onboard experience of our newly redesigned cabins.”
