Plan your connection at Heathrow and free up time to spend as you wish.
If you’ve booked two flights separately, in most cases you’ll need to pick up your checked bags and check-in for your connecting flight. If so, simply exit through Arrivals and check-in at Departures. Be sure to keep a keen eye on the time.
If your connecting flight leaves from a different terminal, simply follow the purple signs to your departure terminal.
