OTOH we all know how hard it is please everyone.

interested to hear your experience with either.
CardStar is the program I use on my Iphone (I know they have an app for droid but not sure about the blackberry) and I think it's great for a free app. If you put your delta SM number in the skyclub is able to just scan the delta SM from the app for entrance, so I am assuming it works for other airlines as well.
