In contrast, legacy airlines may demand tighter integration with lounge and gate infrastructure. All these factors affect bus service coordination between airlines, airport and ground service providers. Therefore, airports serving a diverse airline mix may adopt hybrid ownership and operating models that can accommodate varying service expectations and turnaround profiles. Regional regulations impacting the ownership model In some cases, regulatory frameworks largely determine the model adopted. In Europe, for instance, the European Ground Handling Directive5 plays a critical role in shaping market access and service provision models. The directive mandates the liberalization of ground handling services, allowing multiple service providers to compete in eligible commercial airports – in this case, those with annual traffic exceeding 2 million passengers or 50,000 tonnes of freight. This has led to increased outsourcing, greater price competition and a need for airports to establish robust oversight mechanisms to ensure safety, quality and interoperability across competing providers. As a result, procurement processes have become more structured, often requiring competitive tenders, multi-year service-level agreements and detailed performance metrics. Ultimately, all these factors may become barriers if an airport is willing to change the infrastructure needed for changing the bus fleet. In sum, the business and ownership models of airport bus fleets are neither static nor one-size-fits- all. They reflect a complex interplay of operational configurations, commercial imperatives and regulatory constraints. As airports intensify efforts to reduce their environmental footprint, these models must be carefully assessed and leveraged to pursue the path of least resistance to meaningful progress in sustainability. When fleet decarbonization is elevated to a strategic priority, public-private partnerships and the shift from asset-based ownership to service-oriented mobility contracts increasingly come to the fore – a development further examined in Chapter 4.
