The world's best airline is updating its business and first-class experience

Singapore Airlines unveiled a multi-year cabin refresh backed by more than S$2 billion (about US$1.5 billion) in investment, covering new business- and first-class seats, dining and entertainment across its long-haul fleet. The carrier, repeatedly ranked among the world's best airlines, said the upgrades will roll out progressively, with details of specific routes and timelines to follow. The move matters because premium cabins drive a disproportionate share of long-haul revenue, and rivals in the Gulf and East Asia are simultaneously refurbishing their top-end products. Investors will watch for the delivery schedule, any impact on capital expenditure guidance and how quickly the new cabins reach key routes.
