Frequently Asked Questions
Do I need a visa for a 6-hour layover in London?
It depends on your passport and the destination. Many countries (Singapore, Hong Kong, UAE, Qatar, South Korea, Taiwan) offer free transit visas for 4-24 hour layovers. Schengen countries usually require a visa even for short stops. Check the visa note specific to this guide before you book.
Is 6 hours enough to leave Heathrow Airport?
For 3-hour layovers, leaving airside is risky. For 6+ hour layovers, you can comfortably see one neighbourhood. For 12-24 hour layovers, you can experience the city properly. Always factor in immigration queues (30-90 min) and security on return (60-90 min).
What is the best way to get from Heathrow to London city centre?
Most major hub airports have an express train or metro link that is faster and cheaper than taxis. For short layovers, prioritise the train (no traffic risk). For overnight or late arrivals, a pre-booked transfer is safer.
Is there luggage storage at Heathrow?
Most major airports have official luggage storage at USD 8-20 per bag per day. For cheaper rates, Radical Storage partner shops in the surrounding city charge USD 5-7 per bag per day — book on-app before you land.
