Global Aviation: Market Overview
The global aviation market transported approximately 4.5 billion passengers in 2023, approaching pre-pandemic levels. Growth is being led by Asia-Pacific carriers, where demand has rebounded sharply, while European short-haul routes face increasing pressure from rail expansion and sustainability concerns.
Low-cost carriers now account for roughly 34% of global seat capacity, with their share exceeding 50% in some European and Southeast Asian markets.
