Ahem, as I am somewhat involved with that particular project
, I can say that there was some initial confusion as to who is entitled to use the priority lanes, both among pax and staff. Now, at least during peak times, there should be an airport rep. in front of all those priority lanes checking passengers' boarding passes.
The official policy is "Business and First Class pax only". However, when there are not too many C and F pax in line already, the airport rep. has some leeway to admit status holders and/or Y pax on tight connections as well. But this is never a "right", but merely a courtesy that should not be calculated into the time from lounge to gate.
It remains to be seen if this concept will continue as it is right now...
