Heathrow Airport’s catering income climbed by 5.6% to £19m in the first six months of 2013, as passenger traffic increased 2.4% to £34.4m in the period, driven by European traffic.

Overall, Heathrow’s turnover increased 9.2% to £1.15bn in the six months, with adjusted EBITDA up by 18% to £610m.

Heathrow Airport retail income climbed by +4.6% to £227m.

Heathrow chief executive Colin Matthews said: “Performance at Heathrow this year is encouraging. The number of passengers using the airport increased, passenger satisfaction hit record levels and we maintained solid delivery of our service standards.

“Our earnings support the investment made in Heathrow and that continues with the new Terminal 2: The Queen’s Terminal opening in June next year. We want to build on our achievements and continue that progress over the next five years, which is why we’ve submitted fresh plans to the CAA for a further £3bn of investment, if returns to investors are fair and competitive.”
