Global airline capacity is projected to reach 504 million seats in April 2026, marking a modest 1% increase over the same period last year, according to the latest data from OAG. This figure represents a notable cooling from the rolling year-on-year growth rate of 3%, as global instability continues to reshape international flight patterns and carrier strategies.
As the summer season commences, the Spain–UK corridor has reclaimed its position as the world’s leading international country pair. Capacity for this route has surged by 8.7%, reaching a total of 5.1 million seats. This robust growth underscores a resilient demand for European leisure travel despite broader economic headwinds.
While global growth has slowed, several domestic markets are showing significant momentum:
-
China: Leads as the fastest-growing domestic market, with capacity up 4.1% year-on-year.
-
Australia: Continues a strong trajectory with a 3.8% increase.
-
India: Domestic capacity has officially returned to growth, posting a 3.4% rise compared to April 2025.
Conversely, some Asian markets face headwinds. Growth has stalled in Indonesia, where seat numbers dropped by 0.8%, while the Japanese domestic market continues to contract, falling 2.2% year-on-year.
The world’s largest airlines are seeing mixed results, split largely between those expanding frequency and those scaling back due to operational or regional pressures.
-
Americas: Major US carriers are maintaining steady growth between 2% and 4%. LATAM Airlines Group leads the region with a 6.6% increase in flight frequency.
-
Asia-Pacific: Cathay Pacific reported a significant 15.3% increase in Available Seat Kilometers (ASKs), driven by new European and US frequencies and longer routings to avoid restricted airspace. Singapore Airlines also saw a healthy 4.3% ASK increase.
-
Strategic Reductions: Several major carriers have reduced flight volumes, including Air Canada (-7.8%), Qantas (-5.1%), and British Airways (-1.2%).
-
Middle East Impact: Geopolitical conflict remains a primary disruptor. Emirates saw scheduled ASKs plummet by nearly 40%, while Qatar Airways recorded a 31% decline. OAG notes that Middle Eastern schedules remain highly fluid and subject to further change as the situation evolves.

“The data for April 2026 reflects an industry at a crossroads,” said an OAG analyst. “While domestic recovery in China and India provides a silver lining, the cooling of global growth to 1% highlights how sensitive the aviation ecosystem remains to regional instability and shifting airspace restrictions.”
