Strike action by French public sector workers has been causing major disruption to air and rail services across the country.
Hundreds of domestic and European flights have been cancelled, and public transport in major cities has been seriously hit.
Some 80% of all flights across France were to be cancelled, the French civil aviation office said.
National carrier Air France said it was cancelling 55% of its short- and medium-haul flights. All long-haul services will continue to operate.
Many airlines are offering refunds to affected passengers.
