Nantes Airport uses one terminal common to all flights. The building is quite small and often very crowded.
Security and passport control are efficient and queues last a maximum of 15 minutes. Especially in the morning and afternoon rush hours, expect a shortage of seats after security check.
Transfer between flights
Nantes is not typically a transfer airport and therefore does not have a direct transfer transit zone.
If you schedule your own transfer here, you must always exit the transit zone and go back through security.
