The problem at the core of the mishaps that you describe,
Goldorak, and that have already been described at length on this thread, is the fuzzy logic. Let us forget for a minute about AMS, which is a lost cause, and focus on CDG. Asking for a meet-and-greet service through the Ultimate Assistant team triggers a cascade of events that goes through SCC and KX, and a lot can occur at every step of the way. Regardless of whether or not this is factual, SCC might feel that you have enough time to connect between terminals, while KX, that they are sufficiently understaffed to justify denial of the service that you sought, even though your connection is at risk. Shall I continue? The only way I can think of to ensure a proper service---let us start modestly here---when we have a very tight connection, of say one hour or less between flights, is to remove the fuzzy logic, and demand that SCC systematically requests from KX that they send out someone for assistance. Interestingly enough, since we are talking about the meet-and-greet service, it was offered to me twice in the last quarter of 2021, and on both occasions, not one, but two KX agents were on board the rental car that took me between the phantom 2G terminal and 2E, thereby calling into question the hackneyed argument of an understaffed KX service (supposedly undergoing partial unemployment). This objective should become our priority, and it is incumbent to us to exert pressure on the program management to lobby towards this end. In the absence of fuzzy logic, the meet-and-greet service for all short connections (of one hour or less) should become a real benefit, as opposed to something offered upon availability or for a fee.
