Premium Cabin Upgrades Stall as Regulators Slow Certification
Airlines are racing to install luxurious, technologically complex business-class suites (with sliding doors and configurable layouts) to attract high-spending travelers, but certification delays from regulators are slowing approvals. Some planes wait for seats or doors to be certified, leaving flights with limited use or doors locked open, as examples from United Polaris, Lufthansa Allegris, KLM, and Air India illustrate. Regulators say they’re working to streamline safety testing, but the backlog persists as manufacturers adapt to more differentiated cabin designs.
