Another CC with Elite-Lite benefits is the Continental Airlines Presidential Plus Card (
http://www.firstusa.com/cgi-bin/webc...cont&mkid=674L which offers Presidents Club (& NW & DL) access & Priority Boarding ( CO only - but not complimentary upgrades like real CO elites). You also get Hyatt Platinum.
Annual fee is $395 so may be worth it IF you have a home airport with a CO/NW club in the terminal you fly from but you actually fly other airlines (access does not require travel on CO or its partners - if you can get to the club you can use it) but not clubs of your actual airlines. For example - I am based in AUS an airport with exactly 2 clubs, CO & AA - I can access both (via NW & QF memberships) - I can only access the AA club if I am flying AA but can access CO if I am flying anything else - including Southwest (which I have been forced to do for work some times). Even when I have been flying international first class on United I have used to CO club since UA makes no accommodation in AUS.
This is a specific case where this card MAY be useful - in a lot of larger airports their are either more clubs, or different terminals which limit access.
