Tourism seasonality is the concentration of travel demand into a few months of the year, and it is the reason a Mediterranean beach town can be packed in August and half-shuttered in November. The scale is stark: according to Eurostat, 31.1% of all overnight stays in EU tourist accommodation during 2025 took place in just two months, July and August. That single figure explains most of what travelers experience at the airport counter: peak-season fares, thin winter schedules and hotels that close when the season ends.
The industry is now organizing around the problem. The Tourism Seasonality Summit, now in its fourth year and run by Routes in partnership with Low Season Traveller, will meet from 21-23 April 2027 at the NEST Congress & Exhibition Center in Antalya, Türkiye. Previous editions were held in Bahrain, Seville and Rimini. For travelers, the agenda matters because it targets the mechanics behind when flights exist and what they cost.
The timing is no accident. With travel news increasingly dominated by overtourism debates, the summit's 2027 theme is "Designing Demand Together," and it runs the same week as Routes Europe 2027, also in Antalya. Steven Small, VP of Air Transport Events at Informa, noted that one-third of all EU tourism activity is concentrated in just two summer months, while destinations face overcrowding and pressure on infrastructure.

Why does seasonality matter to airlines and airports?
A route that only pays in July is a route an airline will only fly in July. Seasonal demand shapes fleet assignments, crew scheduling and airport staffing, and it is why some regional airports go quiet each autumn. The summit agenda includes the economic cost of seasonal closures and the commercial case for year-round operations, a direct pitch to airlines, airports, cruise operators, ports and tourism organizations to stimulate off-peak demand and improve destination connectivity.
For the traveler, the practical read is simple. If destinations succeed in building shoulder-season demand, expect more year-round routes, softer off-peak pricing and less extreme August crowding. If they fail, the current pattern holds: full planes in summer, reduced service the rest of the year.
Why not just cap visitors or raise tourist taxes?
Many destinations have introduced visitor caps and tourism taxes, but WTTC research suggests such measures often fail to address the root causes of overcrowding and may risk reducing tourism's positive economic contribution. The organization estimates that restricting tourism growth across 11 major European cities could put up to US$245 billion in GDP and nearly three million jobs at risk over a three-year period.
Ged Brown, CEO and founder of Low Season Traveller, framed the alternative bluntly in the summit's announcement: visitor caps and taxes might ease the pressure for a few weeks, but they do nothing for the hotel that closes when the season ends or the chef who leaves for work elsewhere. His argument, drawn from the summit materials, is that no destination actually knows its own tourism capacity, so the real issue is how tourism is managed across the whole year rather than how many people arrive in peak weeks.

What is on the 2027 agenda?
The announced topics read as a checklist of the seasonality problem's moving parts:
- How airlines, airports, cruise operators, ports and tourism organizations can work together to stimulate off-peak demand and improve destination connectivity.
- The economic cost of seasonal closures and the commercial case for year-round operations.
- Workforce challenges, including how destinations retain skills and talent beyond peak periods.
- Strategies to reduce economic leakage and maximize the value retained within destinations.
- Opportunities in cultural tourism and accessible tourism to attract high-value visitors during quieter months.
- New ways to measure tourism success beyond visitor numbers, including resident wellbeing, visitor value and environmental impact.
That last point is the one most likely to change what destinations actually do. If a city starts scoring itself on resident wellbeing and visitor value instead of arrival counts, the incentives behind marketing budgets, route incentives and hotel licensing shift with it.
Why Antalya, and why travelers should watch it
Antalya is a fitting host for a summit about stretching the season. As a major Turkish leisure destination, it sits at the center of the exact demand pattern under discussion, and hosting Routes Europe 2027 in the same week puts the airlines and airports that set schedules in the same room as the destinations that want longer seasons. Brown said progress comes when airlines, airports, hotels and destinations plan demand together, which is the thinking behind the 2027 theme.
Travel and tourism support one in every ten jobs globally and nearly 10% of world GDP, according to the summit announcement, so the stakes reach well beyond beach resorts. Managing overtourism, the announcement argues, requires collaborative, evidence-based action, with no single organization or sector capable of solving the issue alone.
What can travelers take from all this?
Nothing here changes a booking decision tomorrow. But the direction of travel is legible. The industry's stated goal is to move demand out of July and August and into the rest of the calendar, through route planning, event calendars and marketing aimed at quieter months. Travelers flexible enough to fly in shoulder seasons already capture the benefits: lower fares, emptier attractions and full-service schedules. The summit's bet is that enough coordination among airlines, airports and destinations can make those months attractive to everyone else too.
Whether the fourth edition produces concrete action, after editions in Bahrain, Seville and Rimini, is the open question. The measure to watch is not the communiqué but the schedule boards: if winter and shoulder-season frequencies grow at seasonal destinations in the years after April 2027, the collaboration worked. If they do not, caps and taxes will keep filling the policy vacuum, with the economic risks WTTC has flagged attached.
