Paris Charles de Gaulle Airport

Operating Environment

CDG operates four runways — two parallel pairs at 08L/26R, 08R/26L (north) and 09L/27R, 09R/27L (south). The configuration supports independent simultaneous operations and gives CDG significantly more theoretical runway capacity than London Heathrow's two-runway setup.

Three terminal complexes serve passengers: Terminal 1 (Star Alliance and partner long-haul), Terminal 2 (Air France-KLM hub plus SkyTeam partners across halls 2A–2G), and Terminal 3 (low-cost and seasonal). CDG handles around 70 million passengers per year and is consistently among the top-three busiest European hubs alongside Heathrow and Istanbul.

The airport is operated by Groupe ADP (Aéroports de Paris). All runways are equipped for CAT III low-visibility operations. Night-flight slot rules apply but are less restrictive than at LHR.

Major Carriers

Air France is by far the dominant carrier, with operations concentrated in Terminal 2E, 2F and 2G. Together with KLM (via Air France-KLM group operations), the SkyTeam alliance has unrivalled connectivity at CDG. Transavia France operates seasonal and low-cost routes.

Star Alliance and oneworld partners operate principally from Terminal 1 and Terminal 2A–2C; significant operators include Lufthansa, United, ANA, British Airways, Cathay Pacific, Singapore Airlines, Qatar Airways and Emirates. easyJet and Vueling lead the low-cost portfolio.

Recent Operational Events

Common Disruption Patterns

• Recurring controller industrial action. SNCTA and other unions issue strike notices several times per year. Under French law, minimum-service rules force airlines to pre-emptively cancel up to 50–70% of schedules on notified strike days, even when the action is later suspended. The cancellation wave precedes the strike decision by several days.
• Downstream EU flow effects. Because French airspace is a major transit corridor between Northern Europe and the Iberian Peninsula / North Africa, French controller actions impose ATFM delays on flights that neither depart from nor arrive at French airports. Trans-European traffic is structurally exposed.
• Adjacent labour disputes. Air France pilots, cabin crew, and CDG ground handlers periodically raise industrial action notices that can compound ATC events. Peak summer and Christmas windows carry elevated exposure.
• Winter weather. Île-de-France winter fog and occasional snow events trigger LVPs and de-icing surge demand. Less frequent than at northern European hubs, but they propagate quickly given CDG's connection role.

Surrounding Airspace Context

CDG operates within Paris FIR, managed by DSNA (Direction des Services de la Navigation Aérienne). Greater Paris hosts CDG, Orly (ORY), Le Bourget (LBG) and Beauvais (BVA), creating a complex shared TMA. Routes to Iberia, North Africa and the Mediterranean concentrate in southbound flows; trans-Atlantic and trans-polar routings dominate westbound.

No material GPS interference is reported at CDG itself. Closure of Russian airspace and recurring Iranian/Iraqi airspace restrictions affect Air France-KLM's long-haul portfolio — Asia routings now use longer southern paths via Central Asia or the Middle East. The May 2026 UAE airspace security corridor period briefly impacted onward connection structures.
