There are many sources for aviation news out there. You'll find many in the News section of the Thirty Thousand Feet aviation directory. The News by Email area lists some providers where you can subscribe to free email newsletters. With respect to commercial aviation, these are a few of my favorites:
- Commercial Aviation Today - "Daily Commercial Aviation Intelligence for Airline Professionals." A good source for airline industry news by region.
These two share the same format and some articles overlap, but they are very well done and worth looking into:
- AIA dailyLead - A daily e-briefing containing news for aerospace professionals.
- ATA SmartBrief - A free, daily newsletter created for managers in the airline industry.
If you've got some other favorites, feel free to leave a comment and mention them.
