PARIS — French trains, flights and other public services are set to be disrupted Thursday by nationwide strikes to protest against President Emmanuel Macron’s economic measures.

National railway company SNCF says only 40% of high-speed trains and half of regional trains will be running.

Airport authorities say 30% of flights to and from Paris are to be cancelled. Air France plans to maintain its long-haul flights but warns of disruptions on European and domestic flights.

The Paris Metro is expected to run normally but suburban trains will be affected.

Public servants are protesting against planned changes they say will worsen working conditions.

SNCF workers reject a government plan aimed at adapting the company ahead of opening the service to competition.
