I’ve flown on the world’s only 2 all-business-class airlines. It’s like flying on a private jet but less expensive.

• French airline La Compagnie and Maldives-based Beond fly Airbus planes with only business class.
• The model is historically unsuccessful but the airlines are banking on high-demand niche markets.
• I think both are splurge-worthy for people who want a bougie-but-affordable travel experience.

A roundtrip flight on La Compagnie between Newark and Paris is about $3,500 next month. On the same dates, the cheapest nonstop route on that most of the 32 planes Beond hopes to fly by 2035 will be longer-ranged A321neoLRs and A321XLRs, which would eliminate the fuel stop and open new markets.
