The UK’s busiest airport has been the subject of controversy in recent years, when plans to build a sixth terminal were scrapped by David Cameron’s government after complaints from local residents and green groups, unsurprising given the proximity of the airport to residential areas such as Hounslow , which is why it shuts at night. Passengers embarking on long haul flights from London will most certainly be departing from Heathrow, and the Heathrow Express train will get you there from Paddington in 25 minutes. Additionally there are numerous coach services; even better, it’s accessible by tube. Terminal 5 has the most shops, including designer fashion.
