With the London Olympics less than two weeks away, sports teams from around the world have started touching down in the capital.
At Heathrow, bosses have drafted in extra immigration officers and hundreds of volunteers to help with the huge influx of visitors.
Monday was set to be a day like no other.
“We’re expecting a record breaking 237,000 people to move in or out of the terminals which will be the busiest day we’ve ever recorded if that forecast materialises,” said Tom Willis, Operations Director for Heathrow Airport’s Terminal Four.
There had been fears that Heathrow would not be able to cope, but on Monday at least, it seemed the years of planning was paying off.
“I thought it was going to be a bit more packed,” said Alia Atkinson, a membr of the Jamaican Olympic swimming team.
Security has also been a challenge for Games organisers. The government has been forced to draft in troops and extra police officers after a private security firm failed to recruit enough guards.
