First class travel is back, and it's more luxurious than ever...

First-class airline service has long been the playground of the fabulously famous and fantastically wealthy, with luxuries ranging from free-flowing Champagne and mountains of caviar in the early years to private cabins with a bed and shower on some carriers today.

But after British Airways in 2000 introduced lie-flat seats in business class for thousands of dollars less than first– an innovation that quickly spread throughout the industry – it was hard to argue that it’s worth the extra cash for a few more inches of legroom and a better wine list.

Bookings started to fall sharply as the 2008 financial crisis curbed corporate spending and made public displays of wealth unfashionable, so over the past decade scores of airlines have ripped out some or all of their cushiest and priciest seats.

Carriers today say they may have cut too far, especially as the ranks of the super rich continue to expand and the stigma attached to conspicuous consumption has faded.

With the global economy back in growth mode and the industry coming off three straight years of fat profits, airlines are reintroducing or revamping first-class cabins at a cost that can exceed $100,000 just to manufacture each seat.

Long-haul airlines say charging more than $10,000 for a round-trip ticket in the premium cabin is a profitable way to stand out in an industry that’s come to be dominated by discounters.

“First class is developing better than we’d imagined three or four years back,” Lufthansa Chief Executive Officer Carsten Spohr told staff in a recent briefing. “We’re looking at routes where it makes sense, where we have the customers who want it.” 

Air France says it’s seeing an increase in demand for its La Première first class (below) for the first time in years, prompting it to reintroduce the option on daily flights from Paris to Mexico City and São Paulo and increase its frequency to San Francisco.

British Airways, which in 2016 said it would scrap first class on many routes, plans to revamp the service. The Oneworld member has opened a new first class lounge at New York’s John F. Kennedy International Airport that features private dining booths where travelers can dig into dishes such as lobster bisque with crème fraîche or filet mignon with celery root gratin, each paired with the appropriate chardonnay, pinot noir, or cabernet sauvignon.

Emirates, which offers 29,000 first class seats a week across its network, is adding flourishes such as hardwood floors to its service, which had already set the industry standard with private cabins, onboard showers, and safari binoculars for window gazing.

Although first class is making inroads again, on some airlines it will offer fewer seats. Singapore Airlines is retooling the first class cabins on its new Airbus A380 double-decker jets, but with only six suites instead of the 12 that older planes have (although each looks more like a luxury hotel room than an airline seat, with a full-size wardrobe, bed, and leather chair from Italian designer Poltrona Frau).

Emirates will cut the number of such berths to 11 from 14 on its A380s, and Lufthansa’s Boeing 777 widebodies may get just four first-class seats, down from eight today.

The key is getting the balance right, says John Strickland, director of airline advisory firm JLS Consulting in London. One first-class ticket can generate as much revenue as a dozen in coach or two in business, but the berth occupies only about as much space as five economy seats and one and a half to two business class seats.

“First class has a value, provided it’s used judiciously – not sacrificing profitable sales in business class by taking up too much precious floor space,” Strickland says.

Even a diminished first class can help airlines buff up their image. Emirates and Etihad Airways sell first-class swag such as toys, vanity kits, and moisturizing pajamas on their websites or during flights.

And gauzy promotional photos of chauffeured limousines, opulent lounges, and white-glove service on board can make even passengers crammed into the back of the plane feel as if their airline is offering a standard of luxury beyond what low-cost carriers can manage.

First class is available on thousands of routes globally, though only about 20 of them attract more than 10 paying customers daily for the service, says Samuel Engel, an analyst at consulting company ICF International.

Still, he says, first class makes sense as it can be offered as part of a package for corporate clients or as an occasional upgrade to loyal passengers. And it can help manage occupancy and customer satisfaction in business class, where airlines earn the bulk of their profits. “First class acts as a buffer that allows airlines to overbook in business,” Engel says, “since nobody will mind getting bumped into first class.”
