Business Class Suites: 7 Airlines With Closing Doors In 2026

By 2026, business-class passengers chasing privacy are increasingly getting it—through sliding suite doors. The aviation market has moved from a handful of aircraft with door-equipped seats to a clearer ranking: seven airlines operate the most widebody fleets with business-class suite doors. Lufthansa’s Allegris retrofit is the largest at 28 aircraft, split between 10 Airbus A350-900s and 18 Boeing 787-9s, with only the front-row “Suite” seats featuring sliding doors. China Eastern also has 28 door-equipped aircraft, using Thompson VantageXL on its A350-900s and 787-9s. The article cites Qatar and Delta’s earlier rollouts as milestones.
