In 2026, Paris-Orly Airport (ORY) is located in Transport Zone 4 of the Île-de-France region. However, navigating the fares can be tricky because "standard" Zone 1-3 tickets (like a basic T+ metro ticket) are not valid for travel to the airport. To get there from central Paris via the RER B and the OrlyVal light rail, you need a specific "Paris Région-Airports" ticket, which in 2026 costs a flat rate of €14.00. If you are using a Navigo pass, a "Zone 1-4" or "Zone 1-5" monthly/weekly pass will cover the journey, but a standard "Zone 1-2" pass will not. Additionally, the new Metro Line 14 extension, which fully opened for the 2024 Olympics and is a primary route in 2026, connects Orly directly to central Paris (Châtelet) in about 25 minutes. While the airport is geographically in Zone 4, the transit authority often treats airport travel as a premium "special fare" zone regardless of your physical destination.
