Welcome to the forum and congrats on your approval. Great job on rebuilding, i know it has to feel great!
Congrats on the approval,
thank you for the advice,
and sorry, can't help with the Costco question
Welcome to myFico forums and Congrats on your approval I would go for the TE card if you dont get it , it will only be a SP and a HP only if you are approved!
Good job OP on getting your files cleaned up, you are to be commended, enjoy your new AMEX. I do not know anything about the Costco Amex.
Congrats and as for the second Amex, as Wade said, now that you are an Amex holder, a denial would be a SP, approval would be a HP. One more word, be sure and carry your mastercard abroad, may find more places accept MC than Amex. Again, congrats.
The Costco AMEX doesn't have a Chip card in it yet but it will get one by next year in late 2015 at the latest (AMEX converting all of their cards to Chip & Sign slowly). The cards that I know that are converted right now are the Charge cards, Business Cards and the Blue Cash cards.
Considering you were approved for Delta, I 'll say your chances are 50/50 depending on the rest of your credit portfolio.
