Why Singapore Airlines Is Quietly Shrinking The Cabin That Made Business Class The Irrational Buy

Singapore Airlines is reconfiguring its Airbus A350-900ULR cabins, cutting 36 seats from premium economy to make room for more business class capacity. The change targets yield improvement on the airline’s ultra-long-haul routes, where the carrier has struggled to fill its existing premium economy offering. The article says Air Fares data show premium economy is priced at roughly 1.5x to 2.5x economy, but only 0.3x to 0.5x business class—often making trade-down decisions financially sensible when the gap is large. Examples cited include typical sale gaps on routes from Singapore to cities such as Kuala Lumpur, Bangkok, Tokyo, Hong Kong and London, with sales months including January, March, May, August and November.
