Everything You Need to Know Before Flying from London Heathrow(LHR)
London Heathrow (LHR) is the UK’s busiest airport and one of the most connected hubs in the world. With four active terminals and a sprawling layout, it can be intimidating. Opened in 1946 as a former RAF airfield, Heathrow evolved from basic runways to a global gateway with Terminal 5 debuting in 2008.
Heathrow operates four terminals handling 218 destinations across 84 countries, making it the world’s most connected hub. Located 14 miles west of central London in Hillingdon, it features two parallel runways operating near full capacity. British Airways dominates with a strong presence, alongside carriers like Emirates and United.
