Whenever it comes to defining corporate excellence, businesses rely on their champions the world over—Chief Operations Officers (COOs). In Türkiye, Mehmet Büyükkaytan is renowned in his leading role for powering iGA Istanbul Airport’s global excellence.
In his tenure as COO for nearly a decade, Mehmet’s visionary blueprint has transformed iGA Istanbul Airport from a national crown jewel into a global mega-hub. It is a masterclass in managing unprecedented scale and uncompromising timelines. The reality of transitioning one of the world’s largest infrastructure projects into a seamless operational transport hub required more than just engineering. It has demanded the constant balancing of high-level ambition and determination with the granular rigors of meticulous aviation logistics.
Building an entirely new operational organization from the ground up has been a defining challenge for Mehmet Büyükkaytan and his team. There was no legacy structure to inherit. Every function, process, and culture has been designed from anew; to be staffed and aligned with a long-term vision for the new airport. Assembling the right team has required blending global aviation expertise with local skillsets, and then developing the team according to a high caliber of operational standards.
Mehmet Büyükkaytan feels very proud of his people, of his team and their leadership as they have invested heavily in the airport’s culture by creating a shared mindset. They are disciplined yet agile, technology-driven yet operationally pragmatic. Training, empowerment, and clear accountability has allowed iGA Istanbul Airport to move at speed without compromising safety or service quality. “Our very human infrastructure is the backbone that has enabled us to manage complexity coordinate diverse stakeholders and to respond decisively to changing priorities as the airport has scaled,” he says.
That experience fundamentally shaped Mehmet’s leadership approach. Today, it is rooted in proactive adaptability and collaboration. Mehmet Büyükkaytan recognizes that world-class infrastructure only performs at its best when supported by a cohesive, well-prepared team that has been built, trained, and trusted to turn systemic challenges into strategic advantages.
Solidifying an International Aviation Powerhouse
Managing one of the world’s largest airports requires orchestration at an extraordinary scale. Mehmet Büyükkaytan agrees that ultimately it is a matter of systems leadership. It entails aligning safety, efficiency, passenger experience, and commercial performance within a single operating model.
As a result, iGA Istanbul Airport has solidified its position as a global aviation powerhouse, consistently earning top honors for its operational excellence. According to Cirium’s On-Time Performance (OTP) reports, iGA Istanbul Airport (IST) frequently ranks among the most punctual mega-hubs in the world, often surpassing its European peers with an on-time departure rate exceeding 80%. This achievement is particularly noteworthy given that IST serves as one of the world’s busiest transit points, managing over 1,500 flights daily.
“Our commitment to precision ensures that millions of passengers reach their destinations without the frustration of systemic delays, which reflects the airport’s sophisticated traffic management and infrastructure” says Mehmet Büyükkaytan.
Of course, safety is a non-negotiable foundation. With particular emphasis on runway and apron safety. “Runway availability, apron discipline, FOD control, and ground handling coordination all directly determine operational resilience and network reliability”, says Mehmet Büyükkaytan. “These airside functions are all treated as strategic priorities, with continuous executive oversight rather than purely technical management.
“This framework is most visibly tested during our winter operations. Snow, ice, and low-visibility conditions significantly increase complexity and require scenario-based planning, clear decision hierarchies, and seamless coordination across all of our airside stakeholders,” Mehmet Büyükkaytan says. “Effective runway clearing, de-icing operations, and safe apron traffic management are essential not only for flight safety but also for preventing cascading delays that will impact passenger confidence and commercial performance,” he adds.
Beyond its focus on punctuality and safety, iGA Istanbul Airport sets a gold standard in baggage handling and operational reliability. While the global industry average for mishandled baggage remains a challenge for many major hubs, iGA Istanbul Airport boasts a significantly low lost baggage rate, often reported at less than half of the European average.
With state-of-the-art automated baggage screening and sorting systems that span over 42 kilometers, the airport ensures that luggage reaches its rightful owner with incredible speed and accuracy. Alignment across the organization is achieved through integrated governance and shared performance metrics, where safety, operational continuity, service quality, and revenue outcomes are evaluated together. This is supported by real-time data and a unified operational picture which enables proactive decision-making rather than reactive crisis management.
Mehmet Büyükkaytan emphasizes how this operational excellence drives passenger experience and commercial success: “When safety, winter resilience, and airside discipline are embedded into the operating model, our vast scale becomes a competitive advantage rather than a vulnerability.”
“It is also essential to highlight our most vital asset: the APOC (Airport Operations Control Center). As our core operational strength, the APOC serves as the central nervous system of the airport, orchestrating the entire ecosystem. It ensures seamless coordination across operations, technical departments, and IT, while maintaining a constant synergy with all key stakeholders. By integrating these diverse functions into a single unified command, the APOC ensures that every aspect of the operation, from ground handling to technical infrastructure, works in perfect harmony to deliver peak efficiency.”
A ‘Defense-in-Depth’ Strategic Governance Model
iGA Istanbul Airport is often cited as a benchmark for its operational resilience. However, Mehmet Büyükkaytan claims it is not a result of chance, but of methodical discipline. “Our governance is built on a ‘defense-in-depth’ strategy that integrates ISO-certified frameworks with a culture of proactive risk-based planning.”
Mehmet Büyükkaytan ensures his team goes beyond standard procedures and has worked with colleagues to institutionalize the practice of high-fidelity scenario simulations and stress-testing systems driven by dynamic global variables. This allows the airport’s team to maintain a stable operational baseline even in the most volatile conditions. At iGA Istanbul Airport, decision-making is underpinned by a data-driven discipline:
Mehmet Büyükkaytan says they merge real-time intelligence with long-term strategic resilience, “…ensuring that our consistency is not just maintained but continuously fortified against future uncertainties.”
Balancing immediate operational requirements with long-term strategic foresight is a core challenge of leading a world-class aviation ecosystem. “At iGA Istanbul Airport, we achieve this through a dual-track management approach,” shares Mehmet Büyükkaytan.
He and his team maintain daily rigor by embedding their long-term strategic pillars directly into short-term operational cadence. This is facilitated by a cycle of structured performance reviews and predictive analytics that act as an early-warning system. By digitizing their strategic roadmap, Mehmet Büyükkaytan sees that their daily tactical decisions are never made in isolation; instead, they serve as incremental steps toward their broader vision. “This integration allows us to remain agile and responsive to the industry’s volatility without ever losing sight of our ultimate destination as a global pioneer.”
Leveraging Digital Advantage
Mehmet Büyükkaytan has solidified his leadership style by leveraging advanced technologies. Data and real-time intelligence are the connective tissue of the airport’s operations, serving as the primary drivers for optimizing passenger flow, air traffic, and resource allocation. iGA Istanbul Airport’s technological trajectory has undergone a profound evolution. He explains, “We’ve transitioned from traditional monitoring to autonomous, AI-driven predictive decision-making.”
“This shift was instrumental in the historic launch of our triple runway operations in 2025, allowing our team to synchronize complex ground and air movements with surgical precision. As we look ahead, data-centric intelligence will be the cornerstone of our expansion plans,” he says, adding that it will be the defining factor in the airport’s upcoming transition to fourth runway operations later this year. This will ensure that as IST scales its capacity, it will simultaneously elevate passenger experience and operational fluidity to unprecedented levels.
Mehmet Büyükkaytan also believes in building accountability, ownership, and performance culture across diverse operational teams. He says that while large-scale infrastructure is built with steel and technology, it is sustained by human leadership. “At iGA Istanbul Airport, we believe accountability and ownership cannot be mandated, they must be cultivated. We build this performance culture by aligning every individual’s contribution with our organizational North Star through transparent, tiered KPIs.”
This strategy for excellence is anchored in the iGA Academy, where Mehmet Büyükkaytan says they move beyond basic training to professional empowerment. “Through continuous upskilling and leadership development we transform our teams into a unified force of diverse owners.” This culture of responsibility ensures that every employee feels a direct stake in the airport’s success. It fosters an environment where operational discipline and personal initiative coexist to deliver a world-class passenger experience.
Harmonious Collaboration for Operational Excellence
On a daily basis, Mehmet Büyükkaytan must collaborate with regulators, airlines, ground handlers, and global stakeholders to maintain operational harmony. In an environment as complex as iGA Istanbul Airport, operational harmony is not a byproduct of communication. As he says, “it’s the outcome of deliberate ecosystem orchestration”. As COO, his collaboration with everyone is anchored in two principles: radical transparency and predictive alignment.
Mehmet Büyükkaytan explains, “We’ve deliberately moved beyond traditional, transactional coordination models into a framework of integrated governance and shared operational intelligence.” At the core of this approach is the full adoption of Airport Collaborative Decision Making (A-CDM) as a common operating language. A-CDM enables all stakeholders including airlines, ground handlers, air navigation service providers, and regulators, to operate from a synchronized, milestone-driven view of the airport. This is an approach that aligns aircraft, passenger, and resource flows in real time. Through shared situational awareness there is significant improvement to punctuality, resilience during disruptions, and greater trust across the ecosystem.
This is further reinforced through shared airport operational dashboards, which provide a single version of the transparency across safety, capacity, punctuality, resource utilization, and disruption management. These dashboards are not retrospective reporting tools; they are live, decision-enabling platforms that allow stakeholders to anticipate constraints, simulate scenarios, and take coordinated action before issues escalate.
Mehmet Büyükkaytan insists that equally important is an emphasis on proactive, structured engagement. “We operate through high-level joint committees and regular operational readiness forums that go well beyond routine coordination meetings.” These sessions are forward-looking by design. They focus on upcoming schedule peaks, seasonal demand shifts, regulatory changes, infrastructure works, and emerging risk patterns. By addressing potential bottlenecks before they materialize, they ensure that the priorities of airlines, ground handlers, and authorities remain continuously synchronized with the airport’s operational strategy.
The result is a collaborative synergy in which stakeholders do not react independently to events, but act collectively on shared data, shared objectives, and shared accountability. Mehmet Büyükkaytan adds, “This is what enables us to function not as a collection of separate entities, but as a single, high-performance operational organism: resilient, predictable, and aligned at scale.”
A National Marvel of Global Connectivity
iGA Istanbul Airport operates at the intersection of global connectivity and national pride. For Mehmet Büyükkaytan, translating this responsibility into operational standards and service quality is a crucial part of his job. Thus, recognizing they are not just managing an infrastructure asset but also safeguarding a strategic gateway that sits at the literal and symbolic crossroads of Europe, the Middle East, and Asia. As such, Mehmet and his team translate this profound responsibility into high operational standards by merging global aviation benchmarks with the inherent warmth of Turkish hospitality.
Service quality is driven by the understanding that for millions of passengers, as he describes, “we are their first and last impression of Türkiye. Therefore, our standards are designed to be ‘beyond world-class.’ We achieve this with a culture where safety is non-negotiable, and service is an art form.”
By leveraging IST’s geographic advantage and its commitment to operational excellence, Mehmet Büyükkaytan and his team ensure that every journey through the airport reinforces their nation’s role as a global leader in connectivity and a pioneer in the future of aviation.
Integrating the Core Mandate of Sustainability
For Mehmet Büyükkaytan, sustainability is no longer a peripheral concern; at iGA Istanbul Airport it is a core operational mandate. “We’ve moved beyond compliance to become a global leader in green aviation by integrating environmental responsibility into every layer of our strategy,” he says. Tangible, large-scale investments back this commitment. iGA Istanbul Airport is the world’s first airport to meet its entire electricity demand through its own dedicated solar power plant in Eskisehir. This project sets a new industry standard for renewable energy integration. As the first airport in Türkiye to achieve the Zero-Waste Certificate, Mehmet Büyükkaytan is proud of how the airport has successfully recycled over 34% of its waste in 2024 – a figure that will be aggressively improved year-on-year.
The roadmap to Net-Zero by 2050 is already yielding results; IST is currently tracking 10.5% below its original emission projections, supported by a Level 4 Airport Carbon Accreditation. Beyond carbon, the airport is transforming its ground ecosystem with over 100 electric vehicles, aiming for a 50% electrified fleet by 2030. He assures, “This is not just about reducing our footprint; it’s about proving that the world’s largest aviation hubs can also be the world’s most responsible.”
The Leadership Synthesis of Aviation Philosophies
Learning operational philosophies and best practices from global aviation, Mehmet’s leadership has been shaped by a synthesis of Lean operational methodologies, collaborative governance, and digital-first transformation. Beyond frameworks and systems, IST’s strongest influence lies in the shift from reactive management to proactive, hands-on orchestration. Mehmet Büyükkaytan believes that leadership must be visible, especially on the ground. During complex operations or challenging conditions, being physically present alongside teams, directly accompanying frontline units, and operating from command-and-control centers ensures that decisions are grounded in real-time operational reality. “By combining the efficiency of Lean principles with transparent, collaborative structures and active field engagement, we have created an environment where operational excellence is not an aspiration, but a baseline expectation,” he says.
When asked about how he prepares the organization for future aviation trends such as capacity expansion, digital transformation, and evolving passenger expectations, Mehmet Büyükkaytan says that future-proofing a mega-hub requires a dual commitment to scalable infrastructure and cognitive digital platforms. “We don’t just build for current demand; we design for the next decade of aviation.”
This involves investing in AI-driven passenger-centric innovations and modular systems that can adapt to evolving expectations, ensuring that iGA Istanbul Airport remains not just a participant but a pioneer in the global digital aviation ecosystem.
The Currency of Resilience
As a highly experienced leader, Mehmet’s advice to emerging aviation leaders aiming to manage large-scale, mission-critical infrastructure is this: “In mission-critical infrastructure, resilience is your currency, and foresight is your compass. Prioritize data-driven decisions but never overlook the human element. You should build a culture of empowered leadership by equipping teams with the right tools, continuous learning opportunities, and the confidence to take ownership in high-stakes environments.” He adds, “True leadership is about creating a robust ecosystem where people have both the autonomy to innovate and the capability to lead decisively in their own right.”
Redefining Global Aviation Benchmarks
Looking ahead, Mehmet Büyükkaytan says that the legacy they are building at iGA Istanbul Airport is a direct challenge to the global industry’s status quo. While large-scale infrastructure projects are often synonymous with delays and budget overruns, Mehmet Büyükkaytan and iGA Istanbul Airport have proven that speed and efficiency can coexist with unprecedented scale.
He says, “Our legacy is a blueprint for organizational maturity: a culture where operational excellence, sustainability, and innovation are deeply embedded. Having successfully transitioned from the build phase to one of ‘refine and grow’, we leave behind a global benchmark that shows how an airport can be an engine of national pride. It’s about leading in environmental responsibility whilst ensuring the ultimate standards for passenger experience. We’re setting the example and now we’re inviting the world to follow.”
