Passengers travelling to France this week are being advised that they may face disruption due to a planned national strike over the next few days.
The industrial action is expected to affect both air traffic controllers and airport staff in France, which may lead to flight cancellations and delays.
Air traffic controllers are expected to take action on Thursday (May 19), although airport workers could stage short-team stoppages at Paris’ Orly and Charles de Gaulle airports from Tuesday (May 17).
Eurocontrol, the European air traffic control organisation, is due to hold a conference on Tuesday afternoon to discuss the impact of the planned national strike on airline services.
There is also set to be disruption to rail journeys - including SNCF trains where workers are planning a 48-hour stoppage - and sea services in France from tomorrow.
Eurostar said that it planned to run all services as normal during the strike period.
The train operator added: "Onward connections within France may be affected by this action, and we would encourage all customers to check onward travel plans with the relevant transport provider as soon as possible."
TMC Carlson Wagonlit Travel issued an alert about the potential disruption: “Unless averted, flight delays and disruptions are to be expected. Travellers are encouraged to check their travel itinerary and the status of their flight before departure.”
Cardiff airport has also warned travellers to check the status of their flight if they are travelling to France on Thursday.
French unions are taking industrial action in response to planned changes to the country’s employment laws.
