Marc;
Glad to hear you have good luck with Delta. I seem to call like 30 times before I get an agent with a brain on the phone. except for my Alitalia direct flight to Boston last year in Biz Class, Delta really has not worked that well for me. My Platinum status expires at the end of Feb and I am kicked down to Silver. I obtained all my status by CC spend actually made Diamond one year by doing so but was not able to take advantage of any of the perks..
I figure at this stage of my life I will just earn SPG points or Amex reward points and just transfer into the airline I want to take and just redeem Biz class when I can..
I think Olivia and I are still Scorned from the South Africa trip when Delta got us for the open Jaw and really got us good....
