KLM is set to start flying its new Airbus A350 long-haul aircraft with the World Business Class cabin physically installed but still unusable, after European regulators had not yet approved the airline’s interpretation of seating rules. The affected cabins are expected to remain empty on the early Amsterdam–Toronto service, creating an unusual operational problem for the carrier’s premium offering.
The issue centres on KLM’s first A350s, which feature suites with lie-flat seating and privacy doors, but the seats have not cleared the final compliance process. KLM has taken a conservative approach while the certification review continues under a revised reading of the requirements. The delay leaves the airline unable to sell or use part of its most lucrative cabin even as the aircraft enters service.
The disruption is limited to the new premium cabin rather than the wider aircraft programme, with Premium Comfort and Economy unaffected. Still, the situation highlights how cabin certification can slow the commercial rollout of new products long after an aircraft and interior have been delivered and installed.
