Airport capacity and airline demand for access to airports can not keep pace with each other. •

Passengers are due to nearly double over the next 20 years to some 7.2 billion passengers per year,

However airport capacity is not keeping pace, neither is it forecast to

Passenger Load factors are at all time highs – demand is booming

Aircraft operating are forecast to double in 20 Years according to Airbus and Boeing (forecasts 2017)

There is no doubt, we are entering a period where capacity availability is going to impact the ability to serve the demand that’s forecast.

This significant gap between capacity available and what is required results in excess demand which needs to be managed

Without a process of allocating the capacity available we will see chaos … with more aircraft than stands available, more passengers than the terminal and its systems can cope with.

Given the challenges, airlines would far prefer to have ample capacity and no slot constraints. In an ideal world, airlines would be able to fly where they wanted, when they wanted to match demand, but we are now far from this ideal world unfortunately What does it mean for the passenger? • Airport capacity severely lagging demand •

More airline demand for flights than can be safely handled


Airlines confronted by reducing scheduling options

More and more routes with a slot on each end

Complexity each season securing new access for growth

Complications felt in performance – block time considerations, congestion, lack of resilience at airports and in airspace

Who suffers….the passenger, the business relying on freight


The number of slot coordinated airports continues to grow – in every region. To say Coordination is a short term solution to a lack of infrastructure is no longer realistic … slot coordination is more and more a staple in an industry where capacity is not keeping pace with demand. There are 189 Level 3 (Slot Coordinated) airports in total (30 Nov 2017) 122 Level 2 airports (the lesser congested, schedule managed airports with some peak congestion) Notably China now has 21 slot coordinated airports – perhaps unsurprisingly, given traffic growth and congestion challenges Steady growth in Europe, more recent growth in Americas, from Latin America / South America


Slot Coordinated Airports Forecast Given the continuing growth in passenger demand and cargo forecasts and the comparatively conservative airport development projects we foresee coordination continuing its role in the aviation industry. We have looked at future growth of congested airports; realistically there could be another 100 airports declared full in 10 years – that’s 50% growth - the forecast illustrates the challenge, it is significant. Worst case we could see more than 300 slot coordinated airports in 10 years! This would mean secondary and non-hub airports becoming a feature of coordination statistics. As well as the aviation mega cities and current global hubs we know today. This is a significant problem for the industry – reducing flexibility, disabling ability to meet passenger demand without serious constraints and nonoptimal flight schedules to fit in with available capacity. Unfortunately it also means actual passenger demand will be incredibly hard to serve when there is less than optimal access to the market.


So what do we do given airports are quickly running out of capacity? How do we avoid complete chaos at airports where the demand far exceeds the capacity available, where there are not enough parking positions for aircraft, where the terminals are already congested and passengers experience lengthy queues
