Here's my breakdown of what you may be spending on your dream trip to the City of Light. Plane Tickets Mid January to March tends to be the cheapest time to fly to Paris. Summer and Fall are the most expensive! First Class/Business Class: Roundtrip tickets can run anywhere from $4,500 to $9,000 depending upon how far in advance you purchase them. Economy: Flights from the U.S. can range between $500-$1200 depending upon your city of departure.
