With fewer crowds and slightly cooler weather, September is an ideal time for a trip across the Atlantic. Best of all, fares tend to drop, as seen here with this $270 nonstop from Newark to Paris on Primera Air.

Seen below, we found seats departing Newark on Monday, September 10, returning from CDG on Thursday, September 20. This is a Light Fare, Primera's lowest ticket tier, meaning passengers are limited to one "personal item" weighing no more than 18lbs. The next available tier, PrimeraCOMFORT, includes a personal item, carry-on, and one checked bag, which comes out to $422 on these dates. That's still less than what Norwegian charges on these dates ($530) for its similar fare tier, LowFare+.

You'll find other dates available in September/October.
