India to USA Via LHR 7.5-Hour Layover - DATV Visa Rules (2026)

Browse more guides: India travel | Asia destinations

A common Indian-traveler scenario: you're flying from India to USA via London Heathrow with a 7.5-hour layover. Do you need a UK Direct Airside Transit Visa (DATV) for the connection?

The answer is straightforward: with a valid US visa, you're typically exempt from DATV requirements. Without a US visa, you'd need a DATV for airside transit.

This guide covers the 2026 rules and what to expect at LHR.

Short answer

For Indian passport holders India → London Heathrow → USA with 7.5-hour layover in 2026:

With valid US B1/B2 visa: No UK transit visa needed for airside connection (US visa exempts DATV)
Without US visa: Need UK DATV (~GBP 35) for airside transit
Layover under 24 hours: Airside connection only
Both flights through-ticketed: Stay airside, no UK entry
Want to leave airport during layover: Need UK Standard Visitor Visa (~GBP 115)

Why Indians need UK transit visas

Indian passports are on the UK DATV mandatory list. By default, Indian citizens transiting LHR airside need a DATV.

However, exemptions apply for:
- Valid US, Canadian, Australian, NZ, Japan, Ireland visa holders
- Schengen visa holders traveling to/from Schengen
- US Green Card holders
- Diplomatic passport holders

For India-US travelers with valid B1/B2: US visa exempts DATV requirement.

Walk to US gate: Use Terminal 5 (Air India) or designated terminal
