Are there any commercial aviation news sites that focus on deal announcements and new aircraft programs?

Yes — a few commercial aviation trade/news outlets do a particularly good job covering aircraft orders, lease/deal announcements, fleet plans, and new aircraft programs. The best-known ones include:

Trade/news sites to check

• Aviation Week – Very strong on OEM programs, launch orders, certification, and airline/fleet strategy.
• FlightGlobal – Good for deal announcements, program updates, and airline/OEM coverage.
• The Air Current – Deeper analysis on aircraft programs, market moves, and industry deal-making.
• Leeham News and Analysis – Especially useful for Airbus/Boeing program and market commentary.
• Simple Flying – More general-interest, but it regularly covers orders, deliveries, and new programs.
• AeroTime – Covers airline and OEM announcements, including new aircraft and fleet deals.

If you want deal-focused data specifically

• Cirium and CAPA – Centre for Aviation often have strong fleet/order and market intelligence, though some content is paywalled.
• ch-aviation is excellent for airline fleet/order tracking and aircraft program-related news.

For official announcements

If you want the fastest source for new deals/program launches, also monitor:

• Airbus newsroom
• Boeing newsroom
• COMAC / Embraer / ATR / Bombardier / Dassault newsrooms
• Airline press release pages and lessors like Avolon, AerCap, SMBC Aviation Capital, BOC Aviation
