The Direction générale de l'Aviation civile (DGAC), France's civil aviation authority, has asked airlines to reduce flight operations at Paris-CDG and Marseille-Provence airports on Tuesday, September 29, 2026, due to anticipated public sector strikes. These strikes, organized by a coalition of trade unions known as the public sector intersyndical, are expected to cause disruptions across various sectors, including aviation. To minimize delays and ensure flight safety, the DGAC has instructed airlines to cut their flight schedules on specific days and times. At Paris-CDG, a 5 percent reduction in flights is required between 7:00 AM and 8:00 PM, which may lead to schedule changes, cancellations, or adjustments that affect some passengers. In Marseille-Provence, the restrictions are more severe, with a 25 percent reduction in flights scheduled between 4:00 PM and midnight. Disruptions are also expected at several regional airports, including Nantes-Atlantique, Strasbourg-Entzheim, Limoges, Tarbes-Lourdes-Pyrénées, and Pau-Pyrénées, during specific time slots. However, other airports across France are expected to operate normally. The DGAC advises passengers to contact their airline directly to confirm the status of their flight before heading to the airport, as changes may occur last-minute. Regarding rail travel, SNCF Voyageurs, the national rail operator, stated that most high-speed and regional train services will operate "normally" or "almost normally." However, disruptions are expected on TER regional trains and some lines in Île-de-France, the region surrounding Paris. RATP, the public transport authority in Paris, warned that traffic may be occasionally affected in the city. In the context of the broader national strike, train and RER services operated by Transilien SNCF Voyageurs on behalf of Île-de-France Mobilités will run normally on RER A and B, as well as on lines H, J, K, L, N, P, and U. Other lines will experience reduced service, with some routes operating at less than full capacity. Detailed information about train schedules and disruptions will be available by 5:00 PM on the websites and apps of Île-de-France Mobilités, transilien.com, and SNCF Connect. Transilien SNCF Voyageurs and Île-de-France Mobilités recommend that travelers on affected lines consider limiting non-essential travel on Tuesday, September 29, 2026, and explore the option of working remotely if possible.
