The benefits are exactly as those published here: https://www.flyingblue.com/en/progra.../tier-benefits

Flying Blue is certainly not going to have arranged/contracted for certain benefits with certain partners, and then "hidden" the fact from its members or considered them as "Easter eggs" to be found and discussed on threads like this! ;-)

If someone reports an isolated case of receiving a "benefit" beyond what is required, then it is not evidence of an "unpublished benefit", but rather an agent waiving the rules or granting a benefit they are unaware should not have been granted.
