Great and very detailed report!!!
About EZE's Terminal C, let me tell you that even though it's supposed to be used exclusively by Aerolineas Argentinas, Austral, Air France and Alitalia, the company that manages the airport usually uses some of the gates in Terminal C for other companies' arrivals (especially while Terminal A has no available fingers) because Terminal A have lost 2 fingers due to the construction of the new terminal building that would connect terminals C and A. However, after the construction is completed, which is due in 2013, Skyteam will have exclusivity over the Check-in Hall North (former Terminal B), but not over the gates because the airside would be a whole building connecting Halls A, B and C (this last one domestic).
