Summer Doesn’t Build Culture.
It Reveals It.

Why pressure reveals the organisation you’ve been building all year

Every summer reveals something

During my years in airport operations, I found myself returning to the same question time and again. Why do some airports seem to navigate periods of intense operational pressure with confidence and composure, while others struggle under circumstances that, on the surface, appear remarkably similar?

The obvious explanation is that the summer season places demands on an organisation unlike any other time of the year. Passenger numbers rise, experienced colleagues take well-earned holidays, new employees are still gaining confidence, and even relatively minor disruptions can affect the wider operation. For many years I accepted that explanation myself.

Looking back, however, I gradually came to a different conclusion. Summer rarely changes the way an organisation performs. More often, it reveals how the organisation has been working all along.

Whenever we discuss the challenges of the summer period, the conversation naturally focuses on what happened during those few demanding weeks. Those factors undoubtedly influence performance, but they rarely explain why two airports facing similar conditions can produce entirely different experiences for both passengers and employees.

Some organisations retain a sense of calm even when the pace increases considerably. Decisions continue to be made at the appropriate level, departments support one another naturally and managers remain focused on helping the operation succeed. Elsewhere, communication becomes less fluid, decisions begin to move upwards and managers become involved in issues that would normally have been resolved much closer to the frontline.

Pressure has a way of exposing the habits and behaviours that have been developing quietly over time. When there is sufficient capacity, experienced colleagues compensate for weaknesses, misunderstandings are resolved before they spread and inefficient processes are quietly absorbed. During the busiest weeks of the year, that flexibility disappears, making those same weaknesses far easier to recognise.

Rather than seeing summer simply as the busiest period of the operational year, I began to see it as one of the most honest reflections an airport will ever receive. It reveals whether priorities are genuinely understood, whether managers trust their teams and whether colleagues instinctively work together when the operation comes under pressure.

Over the years I became increasingly convinced that consistency is one of the least celebrated, yet most valuable, characteristics of a high-performing operation. When that consistency exists, people already know what matters because they have experienced it repeatedly through everyday leadership rather than occasional communication. That, in my experience, is where operational resilience begins.

Leadership is experienced, not announced

One of the questions I have been asked most often is how we managed to maintain consistency during periods when the operation was under its greatest pressure. Many people expected the answer to involve planning tools, technology or detailed procedures. Those elements all played an important role, but I have never considered them the real foundation.

The most important work happened long before any summer plan was put into practice. We spent time understanding the everyday experience of the people responsible for delivering the operation. Those conversations rarely centred on equipment or procedures. More often they reflected uncertainty about priorities, inconsistent leadership behaviours and a lack of confidence that decisions made under pressure would be supported.

Gradually, I came to believe that culture is experienced far more often than it is communicated. It develops through thousands of everyday interactions between managers and employees, experienced colleagues and new recruits, and departments that choose either to solve problems together or to protect their own responsibilities.

Our ambition was never to create a different way of working during the busiest weeks of the year. We wanted the operation in July to feel fundamentally familiar. Passenger volumes would change, but leadership should not. Priorities should remain clear, managers should continue coaching rather than controlling and colleagues should know what they could expect from one another every day.

Looking back, I believe that consistency became one of our greatest strengths. It did not remove pressure from the operation, but it gave people confidence. When people know what is expected of them and trust that leadership will remain predictable, they spend far less energy interpreting situations and considerably more energy responding to them.

Workshops and communication campaigns may support change, but they cannot replace the daily leadership behaviours that ultimately determine how people experience an organisation. By the time summer arrives, those experiences have already shaped the decisions people will make when the pressure increases.

Looking beyond the numbers

Every airport reviews its performance once the summer season comes to an end. Passenger volumes are compared with forecasts, waiting times are analysed and operational disruptions are reviewed. Those conversations are necessary because they help us understand how the operation performed. Over time, however, I came to realise that they only ever told part of the story.

Some of the most valuable discussions I experienced took place away from dashboards and performance reports. They happened when managers sat down with supervisors and frontline colleagues to reflect on the weeks they had just experienced. Rather than focusing on individual incidents, they explored the patterns that had emerged across the summer. They discussed where collaboration had worked particularly well, where decisions had become unnecessarily complicated and whether leadership had helped the operation or unintentionally slowed it down.

Looking back, I think those conversations mattered because they encouraged curiosity rather than judgement. They were about understanding why the organisation had behaved as it did when the pressure increased. When organisations invest time in understanding the behaviours and leadership decisions behind operational outcomes, they begin addressing underlying causes rather than visible symptoms.

The weeks immediately after summer therefore offer a unique opportunity. The experience is still fresh, people remember the decisions they made and leaders can still distinguish between assumptions and reality. As time passes, memory naturally simplifies events and uncomfortable moments gradually become less distinct. That is why the most valuable learning often happens before planning for the following summer has even begun.

A different way of measuring success

There is another observation that has stayed with me over the years. The airports that improve most consistently are not necessarily the ones that experience the fewest operational challenges. Every airport encounters disruption. The difference lies in what happens afterwards.

Some organisations restore normal operations and move on. Others become curious. They ask why the organisation responded in the way it did, which decisions made the greatest difference and what the experience revealed about leadership, collaboration and decision-making.

Over time, I became convinced that this curiosity is one of the defining characteristics of high-performing organisations. It creates an environment where operational experience gradually becomes organisational knowledge instead of remaining with individuals.

Performance indicators describe outcomes with impressive precision, but they rarely explain the human dynamics that produced those outcomes. They cannot measure trust between departments, the confidence of frontline supervisors or the consistency with which leadership is experienced across the organisation. Yet those factors often determine how well an airport performs when conditions become less predictable.

Final reflection

Every summer leaves behind two sets of results.

One is recorded in reports, dashboards and performance indicators. The other is found within the organisation itself: in the confidence people have gained, the relationships they have strengthened, the lessons they carry forward and the leadership behaviours that have either been reinforced or quietly challenged.

The first tells us what happened. The second helps us understand why.

Over the years, I have come to believe that the organisations which continue to improve are rarely those with the largest budgets or the most sophisticated plans. More often, they are the organisations that remain curious about themselves. They recognise that every demanding period offers an opportunity to better understand how people think, collaborate and lead when the operation is placed under genuine pressure.

Summer, in that sense, is not simply the busiest period of the operational year. It is one of the few moments when an organisation is able to see itself exactly as it is. Perhaps that is the most valuable insight every summer has to offer.
