✈️ Flight Guide: San Francisco (SFO) → Paris (CDG)

Consider these events when selecting travel dates and book flights and accommodations early if you plan to attend major September festivals in Paris.

September is often one of the best months to fly from San Francisco International Airport (SFO) to Paris Charles de Gaulle Airport (CDG) thanks to lower crowds than peak summer and comfortable weather in Paris.
