Heathrow is the third busiest airport in the world in terms of passenger numbers. It carried more than 69 million people in 2011.
Passengers were left stranded today when a glitch at an air traffic control centre caused chaos at airports across the UK and Ireland.
An air accident investigation is under way after a parked Ethiopian Airlines Boeing 787 Dreamliner caught fire at Heathrow.
A co-ordinator for the Back Heathrow campaign, which is calling for expansion of the airport, has called Boris Johnson's candidacy a "slap in the face".

Boris Johnson's selfish plan to stand in the same borough as Heathrow is a slap in the face to tens of thousands of people in west London.
These people rely on Britain's hub airport and the Mayor wants to close it which would result in more than 100,000 people losing their jobs including many in Uxbridge and South Ruislip.
Heathrow's bogeyman may win the selection battle but he won't get his way.
Passenger Phil Jackson has only received one of his 5 bags after landing in Bogota. Day 6 into his 2 week holiday with a group of friends, he is still waiting for 3 pieces of luggage.
He should have left the capital of Columbia as part of his multi-stop trip but instead, is having to wait around to find out what will happen with his luggage. Some of his friends have moved on to avoid losing out on their pre-booked flights and trips.
It was only a couple of days ago too that he discovered that it was not the airline's fault his luggage had gone missing but was in fact due to massive problems at the baggage systems at Heathrow's Terminal 5.
A Heathrow Airport spokeswoman said "it will take several days" for all of the passengers affected by a computer glitch to receive their luggage.
– Heathrow spokeswoman
We experienced intermittent issues with the T5 baggage system between June 26 and 29 which caused some bags to be processed manually. Passengers can now check in bags as normal.
Manual processing led to some bags not making flights in time. While passengers are receiving bags all the time, it will take several days to reunite all passengers with their bags.
We are very sorry for the disruption passengers have experienced and we are working round the clock with airlines to reunite passengers with their bags as quickly as possible.
A Heathrow Terminal 5 computer glitch has meant some passengers have still not received their luggage days after the problem started.
The technical error began on Thursday and has affected departing British Airways passengers.
Some of the affected travellers had to fly without their hold luggage and many have still not received their bags yet despite normal baggage check-in resuming at T5.
The terminal opened in March 2008 when thousands of bags went missing and there were long delays and cancellations.
Gatwick has said its expansion plans are cheaper and far more beneficial than Heathrow's.
Heathrow and Gatwick airports have both unveiled revised expansion plans to the Airports Commission in a bid to secure permission to build a new runway.
The west Sussex airport said expansion at Gatwick would deliver the following benefits:
- Will achieve £40 billion more in economic benefits to the UK than expansion at Heathrow
- Expansion will deliver more than 120,000 jobs in London and south east England
- Fewer people will be affected by noise pollution
- Around 10 million more passengers would be able to travel with a second runway at Gatwick each year than with a third runway at Heathrow
The Airports Commission is considering the following expansion plans:
- Heathrow Hub
- Thames Estuary
People affected by the proposed third runway at Heathrow will receive an "exceptional compensation" package, the airport's boss has pledged.
– Heathrow chief executive Colin Matthews
We are committed to treating those most affected by a third runway fairly. Since the previous runway plan was rejected in 2010 we have listened to ideas for how we could improve our proposals.
People have told us that we should provide more generous compensation and go further in insulating homes against noise.
We recognise that the expansion of Heathrow deserves an exceptional compensation scheme. That's why we're going further than statutory schemes or Government guidance. People will receive fair compensation in the event that Heathrow expansion goes ahead.
Heathrow's bosses have pledged to allocate £550 million for noise insulation and property compensation for local people.
Heathrow's bosses are set to lay out revised plans for the airport's proposed expansion which includes an improved compensation plan for those affected by the building of a third runway.
Bosses will allocate £550 million for noise insulation and property compensation to local people.
Around 750 homes would need to be compulsorily purchased to provide space for the extra runway at the west London airport.
The proposals, which will be submitted to a Whitehall-appointed Airports Commission, will propose compensation of 25% above market value plus stamp duty costs and all legal fees, in relation to purchasing a new home.
The plans also include making those dropping off passengers at Heathrow by car being subject to the congestion charge - once transport improvements are finished.
Heathrow Airport have denied that any planes issued mayday or distress calls last night but say that some aircraft were re-directed due to the strong winds.
A Heathrow spokesperson said:
"The story in the Sunday Times is untrue. There were no mayday or distress calls received at Heathrow. Due to high cross winds some aircraft were diverted to other UK airports that have spare runway capacity."
