By 2045, air passengers will be older in Europe, younger in Africa, and have higher purchasing power in Asia. As demographics and behaviors diverge, aviation will see a massive shift in who flies and why. Airlines and airports will need to reshape their networks, experiences, and strategies to capture the next wave of global demand.
THE SHIFTING CENTER OF GRAVITY
Air travel is no longer the preserve of elites, and over the past decade, flying has become increasingly mainstream across Europe. In France, the share of executives and professionals among air travelers has fallen by almost 8% since 2010, while the number of students and employees has gained ground — a pattern mirrored in Spain, Italy, and the UK. Retirees remain under-represented (around 7% of travelers versus 15% of the adult population), although this is gradually increasing. This broadening of the passenger base marks a fundamental shift. The most pertinent questions, of course, are how many are traveling, to where, and for how long. Those demographic statistics will shape the next two decades of aviation growth.
In Europe, the working-age cohort (25–64), historically responsible for more than 90% of air trips, is shrinking fast (see Figure 1). Aging is not shifting demand upward: older travelers (65+) fly significantly less. This erosion of the core passenger cohort will limit both leisure and business volumes, particularly on short-haul and high-frequency routes. By contrast, most of the world still stands on the upside of the demographic curve.
Air travel demand can be segmented into four maturity areas based on income and propensity to fly (see Figure 2): from emerging markets where flying remains aspirational to acceleration phases of rapid uptake and, finally, to mature or constrained markets where growth slows and shifts toward value or sustainability considerations.
Asia, Latin America, and the Middle East are entering a phase of demographic and economic alignment, a sweet spot where a growing working-age base coincides with rising disposable income (see Figure 3). Based on our observations, once countries reach roughly $40K in GDP per capita, air travel demand accelerates. This is the “mobility threshold” that turns affluence into flight frequency. These regions are now crossing it, fueling the next global growth wave.
North America remains in a zone of flight maturity. Its demographic base is stable rather than expanding, but travel propensity and spending levels remain robust, supported by strong purchasing power and network connectivity. Africa sits below the threshold: a long-term potential market rather than a near-term growth engine, held back by affordability and infrastructure. For the aviation ecosystem, the message is clear: global growth will come less from mature passengers flying more, and more from new passengers flying for the first time.
Airlines should thus rebalance their capacity and fleet mix toward Asia, Latin America, and the Middle East, where a combination of youth and purchasing power will drive significant demand. European hubs will face demographic headwinds and will need to reinvent themselves — shifting from chasing volume to capturing value through premiumization, connectivity, and differentiated service.
“BLEISURE” TRAVEL ON THE RISE
Across mature markets, business travel intensity remains below pre-pandemic levels, even as economic activity has fully recovered. Since 2019, France, the UK, and the Nordics have each seen a 20%-40% decline in business-related trips, while the US recorded a milder drop of around 10%. Over the same period, GDP grew moderately across these economies, underscoring a clear decoupling between economic performance and corporate mobility.
The underlying reason is structural. The widespread adoption of hybrid work, videoconferencing, and stricter sustainability policies has permanently reshaped how companies manage travel. The most elastic portion of demand — short-haul, high-frequency trips for internal coordination or training — has been replaced by digital alternatives. What remains is a smaller but more purposeful segment, focused on external meetings, client engagement, and strategic interactions that justify the journey.
Leisure travel has proven far more resilient and dynamic — it now drives the bulk of post-pandemic recovery. As professionals seek greater personal value and work/life balance, “bleisure” travel has become more popular.
Around one in three business travelers now extend their trips for leisure, supported by more flexible corporate policies: roughly 80% of employers in Europe and North America explicitly allow such extensions.
This blurring of the traditional boundaries between business and leisure calls for new models of flexibility and segmentation. Airlines and airports must adjust to better serve a broad community of lifestyle travelers (individuals combining work, leisure, and experience) with rising expectations for comfort, choice, and premium service.
DIGITAL NATIVES & NEW EXPECTATIONS
Today’s passengers are younger, more connected, and far less tolerant of friction. They expect autonomy, transparency, and seamlessness across every touchpoint. Today, 85% of passengers of a large legacy airline attempt to solve issues online before contacting customer service, up from 60% before the pandemic. They expect real-time information, instant rebooking, and fully digital identification. Airports and airlines are increasingly judged not just on operational efficiency but on how proactively theycommunicate.
This represents a clear potential — and growing necessity — to move from fragmented systems to integrated digital ecosystems connecting airlines, airports, and ground handlers. Such interoperability will enable a seamless flow of information, allowing passengers to receive consistent, real-time updates on delays, gate changes, and baggage status. Achieving this level of coordination is complex, requiring shared data standards, aligned processes, and stronger collaboration across stakeholders, but it is clearly the next frontier for passenger experience and operational excellence.
However, as highlighted by the same carrier, technology cannot replace human service. With interactions becoming fewer but more critical, passengers expect instant, competent assistance when they do reach a person. The bar for empathy, responsiveness, and problem-solving has risen sharply, creating a dual imperative: excellence in both digital and physical touchpoints.
Digitalization will continue to drive efficiency and personalization, but human connection remains the multiplier of trust and satisfaction. The most successful travel players will combine these worlds seamlessly, delivering technology-enabled experiences grounded in empathy and care.
REGIONAL PATTERNS & NETWORK IMPLICATIONS
Air travel within Europe is increasingly driven by southern countries. Since 2010, Spain, Italy, and Portugal have together accounted for roughly three-quarters of incremental intra-European traffic, reflecting vibrant leisure demand, strong inbound tourism, and the expanding footprint of low-cost carriers. Southern Europe has become the continent’s growth engine, with most northern and central markets reaching saturation.
Domestic air growth follows the same pattern: Türkiye, Spain, and Italy lead the expansion, supported by large domestic networks and resilient point-to-point demand.
By contrast, northern countries, such as Germany, the Nordics, and the UK, show limited or even negative growth in internal traffic (a result of high-speed rail competition, environmental constraints, and maturing connectivity).
Beyond Europe, external connectivity has deepened toward Middle East, North America, and Africa, each reflecting a distinct growth dynamic (see Figure 4):
These patterns are redefining network economics and fleet strategies. Traditional hub-and-spoke models centered on Northern Europe could lose relative momentum, while southern and peripheral airports could become gateway platforms for leisure and hybrid traffic. Experts predict carriers will shift narrow-body capacity toward Mediterranean and island destinations, optimizing seasonality through flexible basing and mixed-fleet operations.
For airports, these shifts could translate into sharper competition for transfer roles and destination branding. Secondary airports in Southern Europe, once considered purely inbound, could evolve into regional connectors, with large hubs in the north focusing on yield management, long-haul positioning, and ecosystem partnerships to remain relevant.
THE NEW FACE OF PASSENGER BEHAVIOR
Not all behavioral shifts are positive. Unruly passenger incidents have tripled since 2015, progressing from sporadic episodes into a structural challenge for airlines and regulators (see Figure 5). According to IATA (International Air Transport Association) data, the rate of reported incidents rose from 0.8 per 1,000 flights in 2015 to 2.5 per 1,000 flights in 2024, based on a stable reporting base of more than 60 airlines representing around 55% of global air traffic. This proves the surge is not statistical noise but a lasting behavioral shift.
