For a one-word summary of the megatrend shaping the world's commercial airliner fleet, read simply "China". Our annual World Airliner Census, built on Flight Fleets Analyzer data, reveals that during the past year the distribution of the global fleet crossed a milestone. A year ago, North America always the biggest fleet region led the in-service jet table with 30% of the global total, ahead of Asia-Pacific and China, with 29%. This year those percentages are reversed.
