Yes, "double-decker" planes are still very much in service in 2026, though they are becoming rarer as airlines transition to more fuel-efficient twin-engine jets. The two primary models are the Airbus A380 and the Boeing 747. While Boeing ended production of the 747 in 2023, many "Queen of the Skies" (especially the 747-8i) are still operated by carriers like Lufthansa. The Airbus A380, the world’s largest passenger airliner, has seen a major resurgence; after being grounded during the pandemic, airlines like Emirates, British Airways, and Singapore Airlines have returned them to the skies. In 2026, Lufthansa is even retrofitting its A380 fleet with new business class seats, projecting they will fly into the 2030s. If you want to experience a two-story flight, look for long-haul routes between global hubs like Dubai, London, Munich, or Singapore.
