A decline in air passenger demand at the height of summer raises questions for businesses that rely on international visitors. For short-term rental professionals, the latest figures from the International Air Transport Association (IATA) highlight the importance of tracking the markets their guests come from.
According to IATA’s September 30 release, global air passenger demand fell by 0.8% in August 2026 compared with the same month in 2025. Available capacity increased by 0.3%, while the passenger load factor reached 85.1%, down 0.9 percentage points.
Demand is measured in revenue passenger kilometres, which account for both passenger numbers and the distance travelled. The decline therefore does not translate directly into an equivalent drop in traveller numbers or arrivals at any particular destination.
Where Demand Is Slowing
Much of the decline was linked to the Middle East. Airlines based in the region recorded a 14.6% fall in total demand. Excluding these carriers, global demand increased by 0.6%.
However, even that growth was just half the pace recorded in July, according to IATA.
IATA’s chief economist, Marie Owens Thomsen, raised the question of whether travellers are adjusting their travel budgets as higher energy prices erode their purchasing power. Geopolitical instability adds another layer of uncertainty. IATA identifies these as questions that will become clearer over the coming months.
Europe and Transatlantic Travel
European airlines recorded 2.1% growth in international passenger demand, while capacity increased by 2.8%. Their load factor stood at 86.8%, down 0.6 percentage points.
Beneath that positive overall picture, individual routes followed different trends. Traffic between Europe and Asia increased by 12.2%, while transatlantic traffic declined by 2.4%, with decreases from several markets, including the UK and France.
These figures cover broader airline networks. They do not specifically measure flights to Greece, nor do they establish that bookings from American guests at Greek accommodation properties are declining.
For property managers who generate a substantial share of their revenue from visitors from particular countries, however, the figures provide a reason to check whether their own bookings are moving in the same direction.
What Hosts Should Monitor
Putting the data to practical use starts with each business’s booking calendar. The key is to identify whether guest origin markets, booking lead times and lengths of stay are changing.
Hosts and property managers can assess:
- Whether bookings from their main source markets are rising or falling compared with the same period last year.
- Whether guests are booking closer to arrival or choosing shorter stays.
- Whether growth from one market is offsetting a decline from another.
- Whether their rates reflect the property’s actual booking pace.
The global slowdown alone is not sufficient reason to apply across-the-board discounts. Pricing decisions should be based on demand in the specific destination and the performance of each property.
For October, scheduled flights indicate 2% growth in available seats, which IATA describes as a sign of cautious optimism. Planned supply, however, does not guarantee that those seats will be filled.
For hosts and property managers, the useful insight will come from comparing that airline capacity with the bookings reaching their own businesses: where guests are coming from, how many nights they are booking and what rates they are paying.
