All-Business-Class Airline offers Buy 1 Get 1 Free to Europe

Europe is home to some of the world's most romantic cities, and the business class-only airline La Compagnie aims to assist couples in traveling there in elegance.

The airline, known for its comfortable lie-flat mattresses and high-end amenities, is running a massive 2-for-1 deal across its network, with business class flights to Paris, Milan, and Nice beginning at less than $2,000 per person round trip.  To receive the discount, travelers must book by February 14 using the promotional code "LOVU23."

The offer is valid through December 31, but there are blackout days.

Travel from New York City to Paris or Milan for $3,800 round-trip for two persons. Travelers can also plan a holiday to the south of France with flights to Nice starting at about $4,800 round trip for two persons.

In 2014, La Compagnie inaugurated its all-business-class route to Paris before introducing service to Milan. The airline also began flights between Newark and Nice last year.
