How many terminals does Heathrow Airport have?

Heathrow Airport has four terminals – numbered 2, 3, 4 and 5.

Across all four terminals, a record of 80.9 million passenger travelled through Heathrow in 2019.

Unfortunately, the Covid-19 pandemic halted the aviation industry and there was limited to zero travel throughout 2020 and 2021.

In 2021, as restrictions started to ease and industries started trying to recover, Heathrow recorded its lowest number of passengers in 50 years, amounting to 19.4 million, which is even less than in 2020 -when the pandemic hit and was strongest – which was 22 million.

Does Heathrow have a Terminal 1?

Terminal 1 opened in 1968 but subsequently closed in 2015.

It was shut down to make way for the expansion of Terminal 2.

Which terminal is the biggest at Heathrow Airport?

Terminal 5 – the airport’s main terminal building – is by far the biggest of the four.

It is almost 3,800,000 sq ft and has more than 100 shops and restaurants spread over five floors.

This compares to Terminal 4 which is 1,135,388 sq ft, Terminal 3 which is 1,065,218, and Terminal 2 which is 430,556 sq ft.

In 2018, Terminal 5 saw a staggering 32.8 million passengers on 210,723 flights.

That is almost three and a half times the number at Terminal 4, almost double Terminal 2, and one a half times Terminal 3.

Can I walk between terminals at Heathrow Airport?

There are fast and convenient transfers available between Heathrow’s four terminals, but you can’t walk between every one.

There is a pedestrian underpass between Terminal 2 and 3 which takes about 10 minutes to walk.

Travellers going between the other terminals have to take a free train or bus, but this is still fairly quick and easy.

Passengers can travel on London Underground services and shuttle trains, providing they have an Oyster card or contactless payment card.

Anyone using the Heathrow Express or Transport for London rail must get a free Inter-Terminal Transfer ticket from one of the machines in the station.

These journeys tend to take around 20 minutes.

A free bus service – numbers 482 and 490 – also runs to Terminal 5 which can take up to 25 minutes.

Travellers can find out which terminal they are departing from or arriving into on the Heathrow website.
