PARIS (AP) — France's parliament granted final approval today to a bill raising the retirement age from 60 to 62, a reform that has infuriated the country's powerful unions and touched off weeks of protests and strikes.

The 336-233 vote in the National Assembly was a victory for conservative President Nicolas Sarkozy, who has stood firm despite the protests — a stance that has resulted in his lowest approval ratings since he took office in 2007.

Protesters aren't yet giving up the fight, since Sarkozy hasn't yet signed the bill. In an attempt to revive a protest movement that has lost momentum, unions plan a new nationwide day of street demonstrations and strikes Thursday that are expected to cause travel problems.

France's civil aviation authority says Thursday's strikes mean airlines must cancel a third of their flights at Charles de Gaulle, Paris' main airport, and half their flights at the smaller Orly airport south of the capital. Airlines generally try to spare long-haul flights in such cancellations.

Unions see retirement at 60 as a cornerstone of France's generous social benefit system, but the conservative government says the entire pension system is in jeopardy without the reform because French people now have longer life spans — an average of nearly 85 years for women and 78 for men.
