Direct flights take approximately 3 hours 40 minutes. Connecting routes can take 7 hours or more, so check the total duration before booking a cheaper fare.
January and February are typically the cheapest, followed by November. July and August are the most expensive, with fares often double the winter rate.
Turkish Airlines flies from Istanbul Airport to Charles de Gaulle, Pegasus operates from Sabiha Gökçen, and Air France serves the route from Paris. Comparing all three in one search is usually worth $30–$80.
Charles de Gaulle for the widest choice of flights and a direct RER train into the city. Orly if it’s closer to where you’re staying. Avoid Beauvais unless the saving is substantial, it’s 85km out and needs a paid coach transfer.
Four to eight weeks ahead gives the best fares. Prices climb sharply inside three weeks, and booking more than five months out rarely saves money on European routes.
