There is a thread on Who would be the next SkyTeam member? but there doesn't seem to be a thread on other general news related to SkyTeam. Anyhow, here are a couple of interesting recent articles:

Korean Airlines mulls CSA Czech stake
The article mentions both QR and KE as being (separately) interested in CSA. Personally, I'd like to see CSA remain in SkyTeam, and so would prefer KE to invest. (Not that a non-SkyTeam investment would necessarily mean CSA leaving SkyTeam, but presumably investment from another SkyTeam airline wouldn't raise such questions about alliance membership). I wonder if potential investment from KE may also be a factor behind CSA's recent decision to restart long-haul services with the Prague-Seoul route.

SkyTeam seeks clarity on proposed China Southern-Air China joint A380 operation
Interesting discussion on CZ's challenges in finding a way to use its A380 fleet profitably...
