Can we use l'aeorgare as well? The road signs to my nearest international airport say l'aerogare rather than l'aeroport.
aérogare represents the buildings of an airport. It doesn't include the roads for the planes or even the planes themselves
Aérogare sounds pretty interesting to me, haha! But yeah, just use Aéroport, it's an international word and it is known (and used!) everywhere.
