Already got my $200 credit in GC's. I applied for the 100K CitiMC and will use that for lounge access, since I am based in CLT and almost always have flown US Air or AA. (CLT has a couple of nice US Airways clubs.)
Also since my Plat Amex annual fee will be due in June I will cancel at that time. I was offered a $500 US/AA credit for the loss of club access which I already have used for GC's. (Already have the Amex credit.)
Since I am not that frequent a traveler I can get by with Admirals Club and the free Chase (Lounge Club) access program. The credit is perfect since I am booking AA (via CX) to Asia this summer. Already have a free (miles) Business ticket and will use the $700 to buy tickets for family.
