France may impose a new tax on airline tickets to fund a planned rail link between Paris and the capital's Charles de Gaulle airport, the transport ministry said .
The government will finalise plans "in the coming weeks" for funding the planned CGD Express line, a ministry official told AFP.
"Such a tax would not be out of the question," Transport Minister Frederic Cuvillier told newspaper Le Figaro, which said the tax could raise up to €400 million ($535 million) for the project.
The rail link, which has been in the planning stages for years, is expected to cost about 1.7 billion euros, with the participation of the state-owned ADP Paris airport operator and three public transportation companies.
The project's backers hope the 32-kilometre (20-mile) line can be completed within the next decade.
