Andrew Tyley, RSHP Director, discusses how airports should seek to place themselves at the centre of a wider mobility ecosystem

Global travel continues to expand despite geopolitical disruption. An emerging middle class in developing economies and a younger generation that values experience-led journeys are reshaping expectations of what travel should feel like. Airports that evolve beyond isolated aviation facilities to become infrastructural anchors at the centre of a wider mobility ecosystem are best positioned to respond to this shift.

High-quality connections between modes of transport enable the enriched, seamless journeys that modern passengers increasingly demand. Recent expansion work on two of RSHP’s airport terminals – Heathrow Terminal 5 and Madrid Barajas Terminal 4 – has highlighted the importance of revisiting the original architectural strategies that took urban planning thinking into the aviation world to prioritise connectivity and multimodal integration – principles that are even more relevant today.

From Isolation to Integration

Historically, airport development focused inward, optimising runways, terminals and airside operations. However, contemporary travel operates as a continuous, multimodal chain. Planning frameworks must now extend “beyond the terminal” envelope, integrating urban transport, regional rail and long-distance networks directly into airport masterplans.

At Heathrow Terminal 5, the station box was designed not only to accommodate existing rail services but also to safeguard space for future lines. That early strategic decision has proved both resilient and cost-effective, enabling expansion without disruption.

Similarly, Bao'an Airport positions its terminal above light and heavy rail infrastructure, creating a vertically integrated interchange between air, rail, bus and private mobility. Unified ticketing, real-time journey planning and shorter transfer times enhance both operational efficiency and user confidence, particularly for first-time visitors.

Such examples underline a broader shift: airports must be conceived as synchronised mobility hubs. Those adopting a guest-centric, end-to-end approach benefit from improved regional accessibility, reduced road congestion through modal shift, and more efficient passenger flows. In turn, they strengthen their role within national mobility strategies and contribute positively to the identity of the city.

Terminals as Connection Hubs

As terminals expand, however, the risk is fragmentation. Extended concourses and decentralised transfer points can erode connection quality and increase walking distances. Madrid Barajas Airport Terminal 4 demonstrates the enduring value of compactness and clarity. Its centralised, intuitive layout minimises movement, while a thoughtful use of colour supports wayfinding and creates a memorable passenger experience. Future expansions must preserve such compactness to avoid decentralised transfer points that erode connection quality.

Priority design strategies include centralised interchange zones, vertical stacking of transport functions, optimised sightlines, consolidated processing points, and flexible gate arrangements. Together, these measures reduce cognitive and physical load on passengers and create terminals capable of supporting both traditional aviation and emerging autonomous and electric mobility systems.

Carbon Footprint of the End‑to‑End Journey

Ground access to airports often produces more emissions per mile than the flight itself, particularly in regions where high‑capacity public transport is poorly integrated. As the aviation sector advances its decarbonisation efforts, airports must consider the full carbon footprint of both passenger and staff journeys and target interventions where emissions are highest.

Self-generated clean energy, integrated low-carbon transport and intelligent planning tools are essential but so too is the careful design of landside areas. Better integration with surrounding communities, reduced unnecessary travel movements and even the provision of workforce housing can significantly lower overall emissions.

The Airport as a Civic Asset

Aviation must reposition itself as one component within a broader urban movement system. Airports that integrate digital journey platforms, coordinate with regional providers and develop mixed-use, community-oriented landside districts will emerge not as peripheral endpoints, but as civic assets supporting both travellers and local communities – connected, resilient and firmly embedded in the life of the city.
