MilesBuzz! - Citigroup Chairman Card?

I received a packet from my Smith Barney broker the other day about their Accel program, which has as a benefit membership in the Citigroup Chairman Card. The packet says the card offers access to "hundreds of private airport lounges worldwide", but there is no list either in the packet or readily available on the internet.

Anyone have any information on this, if it's worth it?

I already can get into CO/NW/DL through the Amex Plat, so I'm specifically looking for AA/UA and other international carriers with this program.

Any help would be much appreciated.

I guess this is SB/Citigroup's black card? I think the whole Accel program is new in the last year.

Some of the benfits you can look up here in case this is not the pamphlet they sent you: http://www.sbil.co.uk/pdf/chairmanbook.pdf (although this may be for the UK only?).

For club access, it says in there: "As a Citigroup Chairman Card cardmember, you have free access to more than 450 Priority Pass affiliated airport lounges worldwide, regardless of airline, class of ticket or other airport lounge memberships."
