Primarily a resource for international travelers, the establishment exudes a vibe of efficiency and professionalism. Don’t be awestruck by LHR’s massive size though; there are plenty of inviting lounges, restaurants, and shops to make you feel more comfortable. Additionally, there are free buses and trains to shuttle you around the airport in case you need to get to a different terminal or catch a connecting flight. More must-know information about London Heathrow is available at Flights.com .
Transportation from the Airport
There are a myriad of options to get to Londontown once you arrive at Heathrow. Utilize the city’s public ground transportation to get to the center of the action. The Underground, fondly referred to as “the Tube”, is a metro system which serves not only the various neighborhoods of London but parts of Hertfordshire, Essex, and Buckinghamshire counties as well. If you choose to forego the Tube, catch a ride on the Heathrow Express. The Heathrow Express is a high-speed train which takes about 15 minutes to get to the centralized Paddington Station. After you’re done saying hello to Paddington Bear at his very own gift shop, exit the station or board a connecting bus or train to further your travels in the city.
Lastly, choose to avoid the hustle and bustle of public transportation by renting a car for your stay in London ahead of time here on Expedia.com. This way, your journey can begin as soon as you land.
