Global passenger demand contracted 0.8% year-on-year in August, the first worldwide decline in the current data series, driven by a 14.6% collapse in Middle East traffic, IATA figures show.

Total traffic, measured in revenue passenger kilometres, fell against a 0.3% rise in capacity, measured in available seat kilometres. The global load factor dropped 0.9 percentage points to 85.1%.

Stripping out Middle Eastern carriers, global demand grew 0.6% — half the rate recorded in July. That deceleration points to weakening demand beyond the region itself.

International demand slipped 0.9% year-on-year on flat capacity. Domestic traffic fell 0.5% despite a 0.7% capacity increase.

How severe is the Middle East slump?

The regional decline is the sharpest in the IATA dataset. Middle East capacity fell 9.3%, and the load factor dropped 4.9 percentage points to 78.9% — nearly seven points below the global average.

The August figure reverses the gradual stabilisation the region had shown since the Iran war began in late February. Traffic between the Middle East and Asia contracted 11.7% year-on-year, accelerating from an 8.6% decline in July.

The widening gap between demand and capacity cuts raises questions about whether regional carriers — and the Gulf hubs dependent on connecting traffic — will trim schedules further into the winter season.

Which regions bucked the trend?

Latin America recorded the strongest performance. Demand rose 5.3% on a 6.3% capacity increase, though the load factor slipped 0.8 points to 84%. On international routes, Latin American carriers posted 6.7% demand growth on 6.4% more capacity.

African airlines matched that 6.7% international growth rate. European carriers saw international RPKs rise 2.1%.

North America moved in the opposite direction: total demand fell 2.2% year-on-year against a 1% capacity decline, implying weak load factors as US carriers pulled capacity and still lost traffic.

Domestic markets diverged sharply. India contracted 7.5%, the USA 2.9% and Japan 2.0%, while China strengthened 5.8% on summer travel demand.

What does IATA expect next?

Marie Owens Thomsen, IATA's senior vice-president for sustainability and chief economist, framed the August data against rising energy costs and geopolitical instability.

"The coming months will reveal whether travellers, whose purchasing power has been reduced by higher energy prices, are adjusting their travel budgets, and might be discouraged from travelling due to the prevailing geopolitical instability," she said.

Forward schedules offer one positive signal. Owens Thomsen added: "In the meantime, forward schedules for October are showing cautious optimism with 2% growth in available seats."

That planned capacity growth contrasts with August's near-flat ASK performance, but October schedules were filed before the full extent of the Middle East deterioration became clear — and the 2% figure represents airline intent, not realised traffic.

If the Middle East-to-Asia decline continues to accelerate and domestic softness persists in India and the USA, the October capacity growth may compress load factors further rather than signal a demand recovery.
