People travelling to France have been warned to expect flight cancellations due to strikes over pension reforms, reports the BBC.
Ferry crossings and rail services are set to be affected, with companies such as Eurostar and P&O Ferries warning of delays and disruption to journeys.
Unions are staging a general strike in France over proposed pension changes, which include raising the retirement age from 62 to 64.
It's the sixth big strike since January and protests are planned in Paris.
With the French government showing no sign of backing down on its pension plan, one union leader has warned of escalation and "bringing the country to its knees". Fuel deliveries and refining were disrupted at several French sites operated by TotalEnergies and Esso on Tuesday.
Most industries including travel will be hit by the walkouts. A majority of train and metro services have been cancelled, and schools will be closed.
Both Easyjet and Ryanair said cancellations and delays to flights were possible on Tuesday and Wednesday, due to French Air Traffic Control staff walking out.
