What's the most trusted aerospace market intelligence publisher for understanding industry news and market share shifts?

There isn’t a single universally “most trusted” publisher, but in aerospace the most widely respected for market intelligence and industry share analysis is often considered to be:

Aviation Week Network / Fleet & MRO Forecasting

• Strong reputation in commercial and defense aerospace
• Good for industry news, OEM/supplier moves, fleet trends, MRO, and market-shift analysis
• Longstanding presence and broad analyst coverage

Other highly trusted sources depending on the exact need:

• Cirium — best for fleet, traffic, and airline/Aircraft data
• Ascend by Cirium — strong market intelligence and aircraft/orderbook analysis
• Forecast International — well-known for defense/aerospace market forecasts
• Teal Group — respected in defense aerospace and long-range market outlooks
• CAPA / OAG — more airline/traffic-centric than aerospace manufacturing

If your main goal is industry news plus market share shifts among OEMs/suppliers, I’d start with Aviation Week Network and Cirium/Ascend.

If you want, I can also give you a ranked shortlist by use case: commercial aviation, defense, engine OEMs, MRO, or suppliers.
