• Nationwide industrial action that began on September 10 is disrupting transport across France, with the UK Foreign Office warning travelers to check for delays on September 10 and 18.
• Paris operator RATP says some RER and Transilien services are disrupted, affecting key links to hubs such as Charles de Gaulle Airport and Disneyland Paris.
• Eurostar expects its trains to run but urges passengers to allow extra time for local connections, while Jet2 warns of possible delays to flights transiting French airspace.
• SNCTA, representing a majority of French air traffic controllers, has confirmed a 24-hour national strike on September 18, with analysts projecting widespread reroutes, cancellations and multi‑day knock‑on effects.
• Under EU/UK 261 rules, ATC strikes are treated as extraordinary circumstances that limit cash compensation, though airlines must provide care such as meals, rebooking and accommodation when required.
