Maybe a detail, but aren't most of those granted and administered outside the FF programs, and therefore outside the rules? I know UA's GS is.

I've seen another designation from United on the account status of several well known CEO's - the letters "VIP". I have no idea what that gets them and how it relates to other designations such as GS.

OK, all of the big airlines have basically the same thing: a super-exclusive VIP club with members invited for reasons other than simply EQM.

Of the EQM-based levels only, I think LH HON is probably the best published tier I've ever seen.

I have to back you up on this. The Premier Card in the top. The group of people who have the card worldwide is under 800. Not even revenue now gets you in the club now.

Well why is it prestigious? If I print up a card for GadgetFreaks frequent flyers and hand 4 out at strip clubs is that more prestigious since there are less than 800? The whole thing seems random and silly to me.

Does US Airways have anything?
 

When I still had Chairmans Pref I sat next to someone who had been given CP for life. Fly several million miles. Not sure they do anything anymore for million mile flyers. Heck, Cust Serv can't even look up how many you've flown and tell us to check our statements. I'm getting close but no one at the airline can say for sure

And I thank you for mine. Who are the other three? :D

Seriously IMHO

US Based
AA Concierge Key
UA Global Services
DL Exec Partner
CO STAR hr & CO Chairman Circle

Europe

BA Premier Card
LH HON Circle
AF Club 2000
KLM Skipper

Asia
SQ PPS & PPS Solitaire

Most of these are revenue based and or VIP courtesy.

You don't get a card. it's a designation on the co system - the agents can see this and often go out of there way to be a BIG help, esp at IAH.
Not all CO* are plats, just like not all UA GS's are 1Ks .

It's revenue based.

It's perfectly British though to create a private super-secret members-only club for the sake of doing so. The perks of BA Premier aren't much given the exclusivity, if you believe things you read here.

Had to add in the US Airways Executive Services program!!
Here's a sample breakdown of the more common benefits of these:
Delta Executive Partner
VIP phone line; Higher Status on upgrade list; Gold Medallion status for companion of choice; 4 award waivers for 1st class or coach travel within 50 states, Canada, Carribbean, Mexico and Bermuda; VIP rewards card when activated worth $350 to purchase airport lounge, flights or any other product or offering; Avis free rental day for up to a g level vehicle; automatic Hilton Gold and fast track to Diamond elite; $20 off next FTD.com purchase

Top of the list for upgrades (clear 120 hours prior to departure (1K members clear at 100 hours)); automatic re-booking with highest priority if there's a schedule change or cancellation; early boarding with 1st Class; use of the United Arrivals facility in select international airports, even if you aren't booked in business or first class; meet and greet at selected airports; dedicated check-in venues at selected airports (O’Hare, etc.); selected gratis upgrades.

American Concierge Key
ConciergeKey Services are provided to a select group of VIPs to facilitate travel on AA. The program is offered on an invitation basis only and is targeted at customers who control travel policy for large organizations. Customers who generate a high amount of revenue for AA may also be invited into this program (those who spend upwards of US$50k a year on travel with AA). Services provided include airport escorts, airplane pre-boarding, and also assistance with flight changes, seat changes, and upgrade requests via their own dedicated reservation line. ConciergeKey representatives will also monitor day of travel of ConciergeKey members and will proactively reroute or rebook travel when necessary. ConciergeKey status allows check-in at First Class counters, as well as access to elite lines through security at certain airports, however it has no effect on upgrade standby listing (ConciergeKey status is not linked to elite status).

@Randy:

Just curious, how many of these do you currently have or have had? :)

KLM Skippers were offered a Club 2000 combi-card at the time of FFP merger.
KLM Skipper grants you access to KLM lounges in AMS with an unlimited number of guests.

Club 2000 does not offer you that perk, nor you can use the AF First Class lounge in CDG with a Club 2000 card.

There are currently 12,000 Club 2000 cards in the World, so it is not an exclusive Club of 2000 members anymore...

Club 2000 is not based on revenue.

Like most airlines "hidden" levels, AF does not advertise about Club 2000. AFAIK, the only corporate available image of the card is here :

have earned two, both legit earnings. I've got somewhere near 17 million miles and am a millionaire with 5 airlines (lifetime with 3 of them) and million pointer with 4 hotel programs. No sandbagging here!
