There’s a fare war going on right now for winter travel between New York and Paris. Of course coach travel to Paris has to be cheap otherwise you’ll just buy cheap business class.

These fares are available almost every day in winter.

Here’s a sample itinerary, it’s non-stop travel on American but in this case a codeshare sold by American’s partner Finnair.

This is an ‘O’ fare that’s $18 each way plus taxes and surcharges.

Key rules to get this fare:

• You must depart the US between January 11 and March 31
  
• 90 day advance purchase
  
• 7 day minimum stay (“TRAVEL FROM INBOUND TRANSATLANTIC SECTOR MUST COMMENCE NO EARLIER THAN 7 DAYS AFTER DEPARTURE OF THE OUTBOUND TRANSATLANTIC SECTOR.”)
  
• $275 change fee

Delta and Air France codeshares on Delta are available for under $400 as well.
