The comfort race on airplanes has heated up: The sky's largest double bed is coming

Singapore Airlines will invest S$2 billion (about US$1.6 billion) to refurbish its cabins, with the centerpiece being what it calls commercial aviation's largest double bed for first-class passengers. The carrier is targeting high-spending travelers to defend its position in the premium travel market as competition among airlines intensifies. The retrofit program covers the airline's long-haul fleet and is aimed at differentiating its premium product from rivals upgrading their own top-tier cabins. Watch for the rollout schedule and which routes receive the new cabins first, along with whether the investment pressures peers to match on premium hard product.
