Having been DL PM for a number of years, still AA EXP and BA Gold, these levels don't really come close to delivering the VIP services HON seems to. I am just a Sen aspiring for "HON-dom' however my opinion is less is more.
Even flying LH F, I see HON's being met - at BKK the other day there was somebody to take the HONs through the VIP line. Coming off European flights at bus gates, I see the HONs being met by car.
For me, the airport is the bad part of flying on both ends. LH's HON program seems to make the airports easy. Obviously, there is just so many people you can handle on a VIP basis like this, so naturally they have to keep ensuring that the HON contingent doesn't grow past their capacity to accommodate them.
Go into the BA F lounge at LHR and it is overrun by Golds and OW Emeralds. I would hate to see the FCT standing room only because of too many HONs
