King Salman International Airport is Riyadh’s PIF-backed KSIA mega-airport, planned across roughly 57 square kilometres on the existing King Khalid International Airport site. The project is designed around six parallel runways, nine terminals, Foster + Partners’ master plan, and a 2030 capacity target of 100-120 million passengers a year before scaling toward 185 million by 2050.
Operated by the King Salman International Airport Development Company (KSIADC) — a Public Investment Fund company chaired by HRH Crown Prince Mohammed bin Salman bin Abdulaziz — the project was formally unveiled by the Crown Prince in November 2022, the master plan competition was won by Foster + Partners in November 2022, and major construction works commenced in September 2025. The third runway construction — a 4,200-metre runway being delivered by FCC Construcción SA and Al-Mabani General Contractors Company — commenced in early January 2026, marking the most institutionally consequential infrastructure milestone of the early 2026 calendar year for the broader KSIA delivery programme. At full completion in 2030, KSIA will be the world’s fourth largest airport by area — surpassed only by King Fahd International (also in Saudi Arabia) and Denver and Dallas-Fort Worth in the United States.
The institutional weight KSIA carries within the broader Saudi state architecture is unusually substantial even by Vision 2030 mega-project standards. The project simultaneously serves as the operational hub for the launch of Riyadh Air (the new full-service Saudi national carrier whose entire commercial proposition depends on substantial international air capacity into and out of Riyadh), as the critical aviation infrastructure dependency for Expo 2030 Riyadh (whose 40-42 million visitor target architecturally depends on substantial international air capacity, with the Expo site itself positioned in northwest Riyadh near KSIA), as the core deliverable underpinning GACA’s broader 2030 target of approximately 330 million annual passenger throughput across the Saudi airport system, and as the operational anchor for the broader transformation of Riyadh into a top-ten global urban economy that the Vision 2030 architecture has explicitly committed to. The simultaneous dependency of multiple high-profile Vision 2030 deliverables on KSIA’s timely commissioning makes the airport’s delivery cadence one of the most institutionally consequential infrastructure variables affecting the broader Vision 2030 endpoint outcomes.
The 2026 institutional momentum has been substantial. In addition to the January 2026 third runway construction commencement, the mega passenger terminal construction is scheduled to begin in 2026, designed to handle up to 40 million passengers annually with biometric check-in, extensive retail, premium lounges, and direct connection to the Riyadh Metro network. Delta Air Lines announced a new nonstop service between its Atlanta hub (ATL) and Riyadh (RUH) for Winter 2026 — one of the more institutionally consequential international carrier route announcements of the year, signalling continued international carrier confidence in the Riyadh aviation expansion. The cumulative architecture indicates a project executing at the cadence the substantial Vision 2030 timing requires, although meaningful execution questions remain about delivery completion against the 2030 target window, the broader regional security environment that has disrupted Gulf aviation throughout 2026, and the operational commissioning architecture supporting the transition from King Khalid International to the expanded KSIA footprint.

What KSIA Is
King Salman International Airport is structured as the institutional vehicle through which Riyadh’s transition from a regionally significant airport hub into one of the world’s principal aviation capitals is operationalised. The 2022 master plan announcement by Crown Prince Mohammed bin Salman positioned KSIA explicitly as a transformational national project “reflecting the Kingdom’s ambition to position Riyadh as a global capital and leading aviation hub.” The institutional positioning is structurally distinctive because it explicitly committed Saudi Arabia to delivering aviation infrastructure at scales that no Saudi airport had previously operated at and that few global airports operate at.
The strategic logic underpinning KSIA operates on five distinct registers, each contributing to the institutional case for the substantial $30 billion capital deployment.
The first is Riyadh’s positioning as one of the world’s top ten urban economies. The Vision 2030 commitment to elevate Riyadh into the top-ten global urban economy tier requires substantial aviation capacity that the existing King Khalid International Airport cannot deliver. The 100-120 million passenger annual target by 2030 places Riyadh at scales currently operated only by the largest global aviation hubs — Dubai International (~92 million in 2024), London Heathrow (~84 million), Atlanta Hartsfield-Jackson (~108 million), Dallas-Fort Worth (~88 million), and the broader top-tier cohort. The capacity expansion is the operational mechanism through which Riyadh gains the international air connectivity that top-ten urban economy status requires.
The second register is the operational hub for Riyadh Air’s commercial launch. Riyadh Air — the new Saudi full-service national carrier launched at the end of 2025 with a target to eventually serve more than 100 international destinations — operates as a hub-and-spoke carrier whose commercial proposition depends substantially on the substantial international transfer traffic that hub airports support. KSIA’s 6-runway, 9-terminal architecture provides the operational capacity that Riyadh Air’s hub strategy requires. Without KSIA’s expansion, Riyadh Air’s growth trajectory would be substantially constrained by the existing King Khalid International capacity ceiling.
The third register is Expo 2030 Riyadh visitor flow architecture. Expo 2030 Riyadh’s 40-42 million visitor target across the October 2030 – March 2031 event window depends on substantial international air capacity into Riyadh during the event period. The Expo site is positioned in northwest Riyadh near KSIA (originally announced near “King Salman International Airport”). The institutional dependency between Expo 2030 visitor target achievement and KSIA’s operational commissioning is therefore structural — meaningful Expo 2030 visitor target shortfall would result if KSIA delivery delays compress the air capacity available during the event window.
The fourth register is GACA’s 330 million 2030 passenger target. The 2030 Saudi airport system passenger throughput target of approximately 330 million depends on substantial KSIA capacity contribution. The current Saudi airport system delivered 140.9 million passengers in 2025 across the existing portfolio. Adding 100-120 million KSIA capacity at 2030 commissioning, alongside substantial Jeddah King Abdulaziz expansion (50M → 80-114M by 2030) and the broader regional airport portfolio expansions, provides the structural pathway to the 330 million system target.
The fifth register is logistics and cargo connectivity. The 2 million tonne annual cargo target by 2030 (scaling to 3.5 million tonnes by 2050) positions KSIA among the largest global air cargo hubs. Combined with the dedicated Terminal 6 for low-cost carrier cargo, the FedEx partnership announced in October 2024, and the Special Integrated Logistics Zone (SILZ) partnership focused on coordinating operational processes and developing infrastructure for air cargo, KSIA’s cargo architecture supports the broader Saudi logistics ambition under the National Transport and Logistics Strategy.
The combination of these five registers produces an institutional case for KSIA that operates at the convergence of multiple Vision 2030 strategic priorities, justifying the substantial $30 billion capital deployment and the senior-level institutional resources committed to delivery.
Leadership and Institutional Architecture
KSIA is developed and operated by the King Salman International Airport Development Company (KSIADC) — a wholly-owned PIF company chaired by HRH Crown Prince Mohammed bin Salman bin Abdulaziz. The Chairmanship structure replicates the institutional template applied across the major PIF strategic-priority companies (NEOM, HUMAIN, Diriyah Company, Soudah Development, Alat, and the broader cohort), placing KSIA at the senior tier of PIF strategic priority alongside the broader giga-project portfolio.
Vice President Ersel Göral provides the operational leadership for KSIADC. Göral’s institutional positioning combines aviation infrastructure delivery experience with the broader Saudi institutional engagement that the senior-level coordination requires.
The institutional architecture nests within the broader PIF 2026-2030 strategy approved by the PIF Board of Directors in early 2026. KSIADC falls within the PIF Vision Portfolio, which catalyses development of six ecosystems within the local economy. The institutional positioning provides the strategic framework supporting continued capital deployment across the multi-year delivery horizon.
The lead delivery partnership architecture combines:
Foster + Partners — the British architectural practice serving as master plan architect, having won the November 2022 master plan competition. Foster + Partners’ broader portfolio includes substantial international airport experience (including Beijing Daxing International, Hong Kong International, Stansted, and Mexico City Airport master plan proposals), providing the institutional credibility that mega-airport delivery requires.
Bechtel — the US engineering, construction, and project management firm serving as a lead delivery partner. Bechtel’s portfolio includes substantial mega-airport delivery experience including King Khalid International Airport’s original construction, providing operational continuity across the KKIA-to-KSIA transition. Bechtel won the contract to deliver three new KSIA terminals.
Mace — the UK construction and consultancy firm serving alongside Bechtel as lead delivery partner. Mace’s contemporary portfolio includes substantial international mega-project delivery experience that complements Bechtel’s institutional capacity.
FCC Construcción SA and Al-Mabani General Contractors Company — partnership delivering the third runway construction (4,200 metres long, multiple access taxiways) under the January 2026 commencement.
Mott MacDonald — appointed as Airports Master plan Framework consultant for airport development across Saudi Arabia, providing the broader airport master plan architecture across multiple Saudi airport development projects.
Jacobs — providing additional consulting and design services across the broader KSIA delivery architecture.
The cumulative international consultant and delivery partner team represents one of the more institutionally substantial infrastructure delivery teams assembled in the contemporary global aviation sector, reflecting the substantial complexity that 57 sq km, 6-runway, 9-terminal mega-airport delivery requires.
The broader institutional partnership architecture includes:
- ewpartners — October 2024 MoU exploring an e-commerce and logistics special economic zone within the airport
- Special Integrated Logistics Zone (SILZ) — coordinating operational processes and developing infrastructure to expand air cargo capacity
- FedEx — strengthening logistics solutions and supply chain capabilities
- Riyadh Infrastructure Projects Center (RIPC) — September 2025 MoU enhancing collaboration on infrastructure and project development
- FII Institute — partnership fostering sustainable development and innovation
The Master Plan Architecture
The KSIA master plan was unveiled by Crown Prince Mohammed bin Salman in November 2022 and developed under the master plan architectural commission won by Foster + Partners. The master plan operates across the following structural components:
The 57 Square Kilometre Site
The total site footprint of approximately 57 square kilometres is structured into:
~45 square kilometres dedicated to airport operations — the runway architecture, terminal complex, taxiway network, apron areas, support facilities, and the broader airfield infrastructure.
~12 square kilometres dedicated to airport support, residential and recreational facilities, retail outlets, and logistics real estate — the aerotropolis component that converts KSIA from a pure airport into an integrated economic district. The aerotropolis architecture is institutionally distinctive among contemporary mega-airports, with the dedicated commercial and residential development providing the broader economic diversification that the project’s $27 billion annual non-oil GDP contribution target depends on.
The Six Runway Architecture
The six parallel runways are designed to support simultaneous arrivals and departures at the operational density required to handle the 100-120 million annual passenger flow and 2+ million tonne cargo flow. The runway alignment is calibrated to the prevailing wind patterns in Riyadh, providing operational resilience across all standard and adverse wind conditions.
The third runway specifically — under construction since January 2026 by FCC Construcción and Al-Mabani — is 4,200 metres long with multiple access taxiways, calibrated to support full wide-body aircraft operations including the largest passenger and cargo aircraft in current commercial operation.
The Nine Terminal Architecture
The terminal architecture includes:
The existing King Khalid International Airport terminals — incorporated into the broader KSIA architecture, providing operational continuity across the construction and commissioning period.
Three new terminals — being delivered by Bechtel under the lead delivery partnership.
An iconic terminal — providing the architectural signature element of the broader complex.
A private aviation terminal — supporting the substantial private aviation traffic that contemporary Saudi commercial flows require.
Terminal 6 — dedicated to cargo operations for low-cost carriers, providing the cargo-specific architecture that the 2 million tonne annual target requires.
A royal terminal — supporting the senior Saudi state institutional travel architecture and the broader VIP aviation requirements.
The mega passenger terminal currently in pre-construction (scheduled to begin construction in 2026, replacing existing facilities at King Khalid International) is designed to handle up to 40 million passengers annually, spanning several million square feet, with biometric check-in, extensive retail and dining, premium lounges, and direct connection to the Riyadh Metro network.
The Wadi Loop Green Infrastructure Corridor
The architecturally distinctive feature of the KSIA master plan is the Wadi Loop — a green infrastructure corridor that builds upon the existing wadi (seasonal riverbed) running through the site to connect the existing west midfield with the new east midfield. The Wadi Loop converts what would otherwise be undifferentiated airport infrastructure into a navigable green-corridor-anchored campus, providing substantial improvements to passenger experience, ecological integration with the broader Riyadh natural environment, and the institutional sustainability positioning that contemporary mega-airport delivery requires.
The Wadi Loop architecture is institutionally consequential because it represents the contemporary best practice in mega-airport sustainability design. The integration of natural landscape features into the airport campus rather than imposing pure built environment across the entire 57 sq km footprint provides ecological resilience, microclimate moderation, biodiversity preservation, and the visual differentiation that distinguishes KSIA from the standard mega-airport architecture pattern.
Sustainability Architecture
KSIA’s sustainability commitments target LEED Platinum certification — the highest tier of the Leadership in Energy and Environmental Design standard. The sustainability architecture spans:
Renewable energy — substantial on-site solar generation supporting the airport’s energy load alongside the broader National Renewable Energy Programme integration.
Natural ventilation and climate-controlled lighting — reducing the mechanical cooling and lighting loads that contemporary mega-airports typically operate at.
Advanced airspace management — operational efficiency through air traffic management technology that reduces fuel burn and emissions across operations.
Green infrastructure integration — through the Wadi Loop and broader landscape architecture.
The LEED Platinum target positions KSIA among the more substantively sustainable mega-airports globally, with the achievement of the certification providing the institutional positioning that contemporary international travel infrastructure increasingly operates within.
