Airport staff and visitors flocked to the fields of the Concorde Club where 300 car enthusiasts lined up their treasured vehicles at the 12th annual event.
About 1500 spectators saw classic cars and motorbikes, as well as enjoying refreshment, funfair rides, a craft fair, and an auto jumble.
Entertainment on the day came from the British Airways pipe band. Motorists entered their vehicles in one of seven categories: American and Custom; Classic; Commercial; Military; Vintage; Motorcycles; Motor Scooters; and each received a commemorative plaque.
Winners were presented with an engraved tankard by management from Allport Freighter, which also sponsored the event. David Winter who works in British Airways logistics department came top of the Vintage category with this 1925 Ford Model T.
A raffle raised £450 which will be donated to the British Heart Foundation.
Garry Court, BA engineer who helped organise the show, said "it was a successful day with many more varies entries than years before, We look forward to seeing more cars at next years Heathrow Classic Car Show which will be held on Sunday 7th July 2013".
