You have a Green Light. This means you have enough buffer to take the Heathrow Express into the city and actually enjoy yourself.
- Step 1: Drop Bags at Excess Baggage Co. (Arrivals, All Terminals). Do not drag your luggage into the city; it will slow you down.
- Step 2: Take the Heathrow Express to Hong Kong Station (Central). This is the fastest way to the city center.
- Step 3: Walk to Hyde Park Stroll. Snap the photo and stretch your legs after the flight.
- Step 4: Stroll over to Little Venice Canal Walk for a scenic change of pace.
- Step 5: Grab a meal at The Mad Bishop & Bear (Pub in Paddington Stn). It offers a great atmosphere without straying too far from the train.
- Step 6: Head back. Do not push your luck; catch the train back to LHR to meet your buffer time.
