Being the capital of the French republic and being one of the top cities of the world, Paris is frequented by millions of people every year. There are several airports built in and around the city of Paris, including Charles de Gaulle Airport.
To catch flights from Paris to Milan, you may have to go to any of the numerous airports that serve the city of Paris. Charles de Gaulle Airport and the Orly Airport are within the city limits, but Châlons Vatry and Beauvais–Tillé airports are outside of Paris. If your flight takes off from the Charles de Gaulle airport, you can admire its avant-garde architecture, designed by Paul Andreu.
