Okay, finally got around to calling to get the platinum changed. They increased the CL to $5,000, changed the card. Then called back to read me some more terms and conditions. I then called to customer care to ask about the signup bonus. They said that the request did not go through for the signature card. I got transferred back to the credit analysis dept, and they did the request again, then went back to customer care, and they said the first rep had already put in the request for bonus miles. So now we wait and see.

A few takeaways for others:
1) Always apply when Recon is open to avoid an additional pull in case you don't get the signature card.
2) Getting approved for platinum is not as bad as it seems. Yes it's a pain to get it increased, however you do get the first year with less of an annual fee, and potentially an additional $50 AS credit.
3) The reasons that they give you if you are denied are not necessarily real. I first called and tried to get it increased and they said they couldn't because my card was open less than three months. It has still been open less than three months, but I was approved for the higher CL.
