Passengers using Eurostar rose by 2% to 4.9 million in the first half of the year.
Sales revenues were up by 7% to £453 million from £425 million in the same period last year.
The high-speed channel tunnel passenger rail service said second quarter traffic grew by 4%. More than 200 extra services have been added between London and Paris as a result to help meet increased demand this summer.
There was a “significant increase” in the number of business travellers in the second quarter of the year. Overall corporate travellers in first half of the year grew by 3% compared to the same period in 2012.
Leisure sales revenues grew by 8% year on year helped by the introduction of several new routes and destinations, including a new winter ski service to the Swiss Alps in partnership high speed operator Lyria, as well as Eurostar’s first new direct service in more 10 years connecting London with Lyon, Avignon and Aix-en-Provence in conjunction with TGV.
Eurostar is now working on plans to introduce a fuller, all year-round service to the South of France from 2015.
Chief executive Nicolas Petrovic said: “We have delivered a strong performance in the first half of 2013, characterised by new routes, extra services and increasing sales revenues.
“A trip on Eurostar continues to be a big draw for international and European travellers alike. We have seen a surge in booking from outside Europe and our new service to Provence has proved a great success with many services running at full capacity.”
He added: “The overall outlook for the business markets is more positive reflecting signs of greater economic stability, particularly in the UK.
“We have seen a return to more normal patterns of business travel which were impacted negatively in the first half of 2012 ahead of the opening of the London 2012 Games.”
