Global air travel is surging faster than ever

In 1970, only about 310 million people flew each year. Today, that figure has exploded into the billions and by 2053, it may more than double again.

According to ACI World and the International Civil Aviation Organisation (ICAO), global passenger traffic reached 9.5 billion travellers in 2024, surpassing pre-pandemic levels and marking one of the fastest recoveries in transport history.

This aligns closely with long-term projections from ACI World, which estimates that air travel could climb to 22.3 billion passengers by 2053.

Global air passengers rose from roughly 1.2 billion in 1990 to 2.6 billion in 2010, then to 4.6 billion by 2019. The only major drop came during the pandemic, and even that downturn proved temporary as demand rebounded sharply.

The fastest growth is coming from Asia and the Middle East. ACI World Director General Luis Felipe de Oliveira noted in the organisation’s forecast release that “Asia-Pacific will account for more than half of global passenger traffic growth in the next 30 years.”

This is already visible in real-world trends such as India’s rise as one of the world’s busiest domestic aviation markets and China’s rapid recovery, where domestic traffic exceeded 2019 levels earlier than many analysts anticipated.

ACI has warned that without significant investment, many major airports will struggle to manage the rising volumes.

Heathrow in London has repeatedly acknowledged that it is operating at near-capacity during peak seasons, and Manila’s main airport has become so overwhelmed that the Philippines has approved a major expansion plan to relieve congestion.
