CDG and Orly serve different route mixes and sit on different sides of the Paris region. Compare the flight first, then the ground journey to your exact destination.
CDG transport
CDG is linked to central Paris by RER B and other ground transport. Terminal layout is complex, so your airline/terminal can affect connection friction.
Orly transport
Orly now has direct Metro line 14 service. For 2026, the dedicated Paris Region <> Airports ticket is €14 full fare for eligible airport journeys.
Changing airports
A CDG↔ORY itinerary is a full landside airport change. Add border/baggage time, the cross-region journey, check-in cutoff and security at the second airport.
How to choose
Compare your Paris neighborhood, flight timing, airline/terminal, public-transport route, bags and whether an airport change appears anywhere in the itinerary.
