The Biz version of the Explorer card has the 100k mile bonus right now but no AF waive. Addl 40K miles for the 99 bucks probably a fair value IMO.
I will say, I have the Club card and every time I fly we use the Clubs at hub airports and/or MSP. That is for our entire family of four. I figure that saves us $75-$100 eating in the terminal each time, if we fly four times a year thats $400 saved and makes up much of the AF itself. let alone the other bennies. The Biz version of the Club card has a nice bonus right now with 1000 PQP if you need them.
