About the London → Delhi route
London to Delhi is proper long-haul — nearly 6,700 km and just under eight hours in the air. That puts it in the sweet spot where you're tired enough to actually sleep but not so wrecked that you land feeling like a different person. It's one of those routes that carries everyone: British-Indian families visiting relatives, corporates doing deals in Gurugram's office parks, first-timers chasing street food and temples. Air India and British Airways both fly it non-stop from Heathrow, which means you've got real choice on comfort and price.
Why travel from London to Delhi?
Honestly? Delhi rewards repeat visits in a way most cities don't. First-timers from the UK tend to make a beeline for Old Delhi — specifically Chandni Chowk, where the food alone justifies the flight. But there's also the obvious pull of history: the Red Fort, Humayun's Tomb, Qutb Minar. Beyond the sightseeing, loads of UK travellers use Delhi as a base for Rajasthan or the mountains. Then there's the family connection factor — the UK has one of the largest Indian diaspora communities in the world, and this route carries an enormous amount of that emotional freight. Business travel between the two capitals is growing fast too, particularly in tech and finance.

Practical tips for LHR → DEL
October to March is genuinely the best window — cooler, drier, and fares tend to dip outside of Christmas. Avoid November if smog bothers you; Delhi's air quality gets rough. At Indira Gandhi International, immigration can move slowly so budget extra time. The Delhi Metro Airport Express runs directly into the city center in about 20 minutes — cheap, fast, skip the taxi queue. UK passport holders need an e-Visa, which is straightforward to apply for online. Carry some rupees for small purchases — cards aren't always accepted everywhere. Flying east means jet lag hits harder in the mornings, so plan your first day light.
