LHR airport guide
London Heathrow Airport
Practical support for Heathrow connections, terminal movement, delays, passport control, and baggage problems.
Practical orientation
Heathrow is connection-heavy and terminal choice matters. Start with your operating airline and terminal, then follow flight connections signs unless you are told to collect baggage or exit.
Terminal and connection considerations
Some connections involve buses, trains, security screening, or passport control. Build in more time if you are switching airlines or holding separate tickets.
What to do if delayed
- Monitor connection risk early if your inbound flight is late.
- Ask the airline whether you should continue to flight connections or visit a service desk.
What to do if a connection is missed
- Use the airline transfer or service desk before exiting arrivals.
- If you entered the UK because of the disruption, check baggage and hotel instructions carefully.
Changing terminals
- Follow purple flight connections signage where applicable.
- Check whether your terminal movement keeps you airside.
Long layovers
- Heathrow has many services, but they are terminal-specific.
- Do not count a long layover as free city time until document and return timing are clear.
Baggage problems
- For missing bags, report with the last operating airline.
- Keep the property irregularity reference and delivery address.
