French air traffic controllers and railway staff are set to join the walk-out, which is likely to lead to delays to flights and rail services from around 6pm this evening.
Air passengers are advised to check with their airline before they travel to the airport, and it is likely that long-haul flights to and from France will be prioritised in the event of major disruption.
Easyjet said it was unsure how severe the impact of the strike would be. “Our aim will be to protect our customers travel plans and keep them fully informed,” said a statement on its website.
Jet2.com said it was anticipating delays to some of its flights to France, or to those operating through French airspace.
“We would like to reassure our customers that Jet2.com will do everything possible to ensure flights operate as scheduled,” said a spokesman. “We would ask that all customers check-in on time as we will be boarding flights for an on-time scheduled departure.”
Meanwhile, further industrial action by Air France workers could lead to more problems for travellers on Friday.
The airline said disruption would be “limited to a few delays”, but advised passengers to check its website for updates.
This week’s strikes follow a 10 day walk-out by Brittany Ferries staff last month, which affected tens of thousands of people travelling from Poole, Portsmouth and Plymouth to ports in northern France and Spain.
