Sorry Video I cannot see how a service which has been publically offered for well over 10 years on a twice weekly basis can be thought to be "secret" by any normal definition of the word. The flights are well known, a lot of people on here have taken them. They appear in guides such as the OAG monthly worldwide flight guides that anyone can buy and which travel agents subscribe to across the world. You can (or could) book them over the Internet or through your travel agent.
The Argentinians know all about them
The "inside information" was are they still selling tickets to civilians......................
