Thanks to all who gave response my post on which one to choose - the Delta Gold or Platinum. Since I have had enough of American Airlines delays, I decided to start flying Delta. I was preapproved for both. Since they are offering 75k for $3,000 spent and medallion qual miles, I opted for the platinum and came out of the garden to apply.
Since I have several other AMEX cards, I thought it would be a sp as the others (other than the first one). Unlike the others, I did not have an immediate approval which was concerning because if they attempted a hp, all credit was frozen. I receive the email stating they needed to review and would get back to me if they needed additional info. (I was stupid and applied on Saturday afternoon. No one would look at it until Monday).
Rather than calling, I checked their online application status this morning. It stated check back in 24 hours. I decided to go on with my day. A couple of hours later, I received an email stating the application had been approved. Not sure of the sl, but happy to have this card.
Congrats on your approval!!! I got the Delta Plat last month myself and am loving it!! Good choice.
