JetBlue Mint Pioneered Business Class Doors in 2014, Predating Qatar and Delta
Years before Qatar Airways' QSuite and Delta One suites grabbed headlines, JetBlue quietly introduced the aviation industry's first business class seats with sliding privacy doors on its transcontinental A321 service.
A common misconception credits Qatar Airways or Delta Air Lines with introducing the first business class seats featuring privacy doors, but the honor actually belongs to JetBlue Airways, which launched the innovation in June 2014—three years before its competitors.
When JetBlue debuted its Mint business class cabin on Airbus A321-200 aircraft serving premium transcontinental routes, the product included four seats equipped with sliding privacy doors, an unprecedented feature in the business class segment at the time. The launch caught the industry off guard, as JetBlue had previously operated as an all-economy carrier focused on shorter Northeast and Caribbean routes.
The Mint cabin featured 16 seats total based on the Thompson Vantage platform, a staggered configuration alternating between paired seats and solo seats. While this seating arrangement had appeared on widebody aircraft before being adapted for narrowbodies, JetBlue's implementation remained unique as the only version of the original Vantage product to incorporate privacy doors. Only the four solo seats received the door feature, with the remaining dozen seats in the cabin lacking this amenity.
The doors themselves differed significantly from the substantial barriers found in premium products like Emirates first class or Singapore Suites. JetBlue's version featured relatively small, low-profile doors that, while offering privacy, were notably shorter than the doors that would later appear in competing business class suites from other carriers.
Despite this first-mover advantage, the original Mint seats have faded from industry memory as Qatar Airways' QSuite, unveiled in March 2017 and entering service that June, and Delta's announcement of Delta One suites in August 2016 garnered more attention. Both products launched with all seats featuring doors, unlike JetBlue's partial implementation, which may explain why they receive more frequent credit for the innovation despite arriving years later.
