Channel Tunnel operator Eurotunnel has said demand from holidaymakers has helped to lift traffic on its shuttle services.
Vehicle numbers rose 15% in the three months to September from a year ago.
Eurotunnel also generates income by charging other freight and passenger services, such as Eurostar, to use the tunnel.
Across the company, like-for-like revenues were up by 8% at 181.3m euros ($252m; £158.6m)
Eurotunnel said that 14 August was its busiest day on record, seeing it carry 14,975 cars, motorbikes and coaches.
The company said that a squeeze on holiday budgets in the wake of the recession meant holidaymakers looking for better value for money by taking a car full of passengers through the tunnel at a fixed price.
It added it had also benefited from customer disaffection with air travel following disruption caused by the volcanic ash cloud earlier in the year.
"As a result... Eurotunnel's traffic grew substantially and the company succeeded in adapting rapidly to the rise in demand," it said.
