Best direct flight routes from UK to South Asia

Highlights

• Conflict in the Middle East has caused disruption to global air travel
• Passengers are increasingly opting for direct flight to avoid disruptions
• Here are the best direct routes from the UK to South Asia

Amid growing tensions between US and Iran, airlines have been forced to cancel or divert flights across the region. This has affected air travel globally as the Middle East serves as a vital halfway connection point for major long haul flight routes.

As passengers navigate the growing uncertainty of air travel ahead of the busy summer, direct flights are proving to be the safest solution.

For those travelling to South Asia, here are the airlines offering the best direct routes from UK

1. UK to India

Air India is your best bet for the cheapest direct flight option to India. The airline has recently doubled down on its direct flight options, offering multiple daily flights from London Heathrow to major Indian cities like Mumbai, Delhi, Bengaluru, Amritsar, Kochi and Hyderabad.

Virgin Atlantic, with its competitive pricing, also flies direct from London Heathrow to Delhi and Mumbai and is worth considering for those who prioritise cabin comfort.

Indigo, India’s largest airline by market share also began a daily direct flight from London Heathrow to Mumbai in October 2025, which it has now expanded to Delhi.
