Virgin Atlantic operates a daily flight between Delhi and London Heathrow.
In a release today, the airline said the Brexit calculator will help holiday makers in India work out how much they could save on a trip to the UK.
"With an exchange rate of 1 Indian rupee to 0.012 British pound, the campaign draws attention to the bright side of Brexit and emphasises that there has never been a better time to book a trip to the UK," it added.
Brexit refers to the UK leaving the European Union.
Virgin Atlantic Airways' Head of India and Middle East Nick Parker said the Indian rupee is at a record high against the pound, "which means you will save on literally everything when you visit the UK".
