The decline was so significant that it pushed overall global air passenger demand into negative territory despite continued growth across most other regions.
According to IATA, total global passenger demand, measured in revenue passenger kilometres (RPK), fell 3.4 per cent year-on-year in April, while international traffic declined 5.3 per cent compared with the same month in 2025.
The association said the downturn was overwhelmingly driven by the aviation crisis unfolding in the Middle East.
“The 46.6% fall in demand for carriers in the Middle East due to war in the region was so acute that it dragged overall demand down 3.4%,” said Willie Walsh, IATA’s Director General.
Conflict reshapes global aviation patterns
The latest figures underscore the central role Middle Eastern airlines play in global aviation.
For decades, carriers based in the Gulf have acted as major connecting operators linking Asia, Europe, Africa and North America through large hub airports.
The ongoing conflict involving Iran and wider regional instability disrupted those traffic flows, leading to a sharp reduction in passenger demand and capacity.
IATA reported that Middle Eastern carriers experienced:
- 46.6% decline in total passenger demand
- 37.2% reduction in capacity
- 12.5 percentage-point fall in load factor
- Load factor declining to 70.6%
Within international markets specifically, Middle Eastern airlines saw an even steeper decline.
International demand fell 48.1 per cent, while capacity dropped 38.4 per cent year-on-year.
Load factors fell to 70.1 per cent, down 13.1 percentage points from April 2025.
According to IATA, traffic remained heavily affected by the ongoing Iran-related conflict, although demand deterioration eased slightly compared with March following the implementation of an uneasy ceasefire.
Global market would have grown without Middle East disruption
IATA's data showed that the aviation downturn was largely concentrated within the Middle East.
When Middle Eastern traffic is excluded, global passenger demand actually increased.
The association reported:
- Global demand excluding the Middle East rose 1.2%
- International demand excluding the Middle East increased 1.9%
- Most major regions recorded positive growth
The figures suggest that the broader recovery in international aviation remains intact despite geopolitical disruption.
Several regions delivered solid performance during April, offsetting part of the Middle East decline.
Asia-Pacific and Europe continue growing
Asia-Pacific airlines recorded a 3.0 per cent increase in international passenger demand, making the region one of the strongest performers globally.
Capacity increased by 0.7 per cent while load factors reached 87.5 per cent, representing a record April level for the region.
However, IATA noted that traffic growth slowed on the Japan-China corridor because of continuing political tensions between the two countries.
European airlines reported a 0.9 per cent increase in international demand.
The region also benefited from changing travel patterns caused by Middle East disruptions.
According to IATA, direct traffic between Europe and Asia increased 15.3 per cent as airlines and passengers shifted away from routes traditionally transiting through Middle Eastern hubs.
Capacity among European carriers increased by 0.3 per cent while load factors improved to 84.9 per cent.
Latin America delivers strongest growth
Among major aviation regions, Latin American airlines posted the strongest growth during April.
Passenger demand increased 8.9 per cent year-on-year, supported by a 7.2 per cent rise in capacity.
Load factors improved to 84.6 per cent, reflecting continued strength across regional and international travel markets.
Meanwhile:
- African airlines recorded 2.2% growth
- North American carriers reported flat demand growth
- Asia-Pacific carriers increased traffic by 3.0%
- European carriers grew by 0.9%
The contrast highlights the extent to which Middle Eastern carriers have become outliers amid otherwise resilient global travel demand.
Higher fuel prices create additional pressure
Beyond the immediate impact of the conflict on passenger demand, airlines are also facing rapidly rising operating costs.
IATA reported that jet fuel prices more than doubled during April as geopolitical tensions disrupted energy markets.
The increase is expected to place additional pressure on airline profitability and passenger demand.
According to Walsh, airlines are already responding to the changing economic environment by adjusting schedules and capacity plans.
Forward booking and scheduling data indicates that carriers are reducing planned services in the coming months as they balance weaker demand against significantly higher operating costs.
Industry analysts note that fuel remains one of the largest cost categories for airlines globally, making prolonged price increases particularly difficult for carriers operating on thin margins.
Domestic markets show mixed performance
Domestic air travel delivered a mixed picture during April.
Overall domestic demand remained flat compared with April 2025, although performance varied significantly between countries.
Growth was recorded in:
- China (+1.2%)
- Japan (+3.7%)
- Brazil (+2.6%)
Declines were reported in:
- India (-2.9%)
- United States (-0.6%)
- Australia (-0.4%)
Domestic capacity increased 0.8 per cent globally, while average load factors slipped to 81.9 per cent.
IATA noted that Japan's domestic market continued to improve despite eight consecutive months of declining capacity, leading to stronger aircraft utilisation.
Airlines brace for uncertain months ahead
The April figures illustrate how quickly geopolitical events can alter aviation demand patterns across multiple continents.
While most regions continue to report passenger growth, the scale of disruption in the Middle East has created ripple effects across airline networks, fuel markets and international travel flows.
The redirection of Europe-Asia traffic, falling demand through Gulf hubs and rising operating costs are already reshaping airline planning decisions for the second half of the year.
IATA said the aviation outlook remains highly volatile as airlines navigate elevated fuel prices, changing passenger behaviour and continued geopolitical uncertainty.
For now, the industry remains operationally resilient, but April's figures show that conflict in one strategically important region can still have a profound impact on global aviation performance.
