LONDON (Reuters) - Passenger traffic at London's Heathrow airport rose 3.9 percent in March, boosted by strong growth on European and Chinese routes, Heathrow Ltd said on Friday. Of the 5.9 million people who passed through the London hub last month, passenger numbers to China rose 15.1 percent year-on-year with India also delivering good growth, the British airport operator formerly known as BAA said.

Spanish construction group Ferrovial, owner of London's Heathrow airport, said Tuesday its net profits plunged 43 percent in 2012 after major one-off gains the previous year. "The 42.9 percent decline in net profit is attributable to the extraordinary gains obtained in 2011," which totalled just over one billion euros, it said in a statement. "A significant portion of that figure did not represent a cash inflow since it was attributable to the revaluation of Heathrow Airport Holdings," Ferrovial said.

By Rhys Jones LONDON, Jan 28 (Reuters) - Britain's government pressed ahead on Monday with a planned high-speed rail link that is opposed by many of its own lawmakers, striving to show it is committed to projects that will eventually revitalise a moribund economy. The route for the second phase of the $50 billion HS2 rail project will run between Birmingham in central England and Leeds in the north, slashing journey times to London by almost a half, the Department for Transport (DfT) said.

LONDON, Jan 21 (Reuters) - London's Heathrow airport cancelled 10 percent of flights on Monday, a day after it cut its capacity by a fifth, and said services could face further delays with more snowfall expected. Heathrow, Europe's busiest airport, said it had cut around 130 flights - most operated by IAG'S British Airways - from its schedule on Monday to allow more space between aircraft because of low visibility.
