Delta Air Lines A350s

Suites in the skies — airline seats with doors that slide shut to give passengers total privacy — have become de rigueur in international first class: Emirates and Singapore Airlines are two of the carriers that offer them on long-haul flights. But an all-suite business class? It has yet to be heard of, according to Delta Air Lines, and the carrier wants to be the first in the industry to change that with the fall 2017 debut of the Delta One suite in its Delta One business-class category.

“This product is meant to be as close to a private jet experience as possible and is driven by our customers, who were telling us that they wanted more privacy,” said Tim Mapes, Delta’s chief marketing officer.

“Right now, we are focused on what these suites give our passengers, and that’s more privacy and much more personal space,” said Robbie Schaefer, Delta’s onboard product manager.

The initial all-suite Delta One cabin will have 32 seats, compared with the 26 to 38 seats on Delta One classes. Besides a fully flatbed seat with direct aisle access, which the airline introduced eight years ago in Delta One, each suite will have a door that slides shut and is as high as the seat.
