This China Travel Daily article discusses the significant changes airlines are experiencing as they adapt and integrate retail strategies into their operations. One key aspect of this shift lies in the significance of airline-specific IT systems, which have lately been under scrutiny. Several lines of questioning are being considered: how to achieve personalisation across all points of customer interaction, how to trigger revenue growth by retailing flights, as well as ancillary services like hotels, cars, insurance, transfers and destination activities, and why stepping away from rigid, hard-coded solutions tied to a specific passenger service system (PSS) or channel might be beneficial. Traditional IT systems also face the threat of newer platforms that can be integrated with or “wrapped around” legacy airline systems, leading to potential changes in handling merchandising, pricing, scheduling, and availability.
