From the forums here and my experience, scores in the 700s, Along with that, a decent repayment history. As for myself, I had a FREEDOM CARD for twelve months before an Airlines Card. I apped on the web and was instantly approved, card arrived in about a week. More recently, Chase granted me a CLI to over $ 20k on my Airlines Card. It was a HP and additional information was gathered. It too was immediately honored/granted. I do know that an excellent payment history is a good to have with Chase. THey also seem to favor low credit card balances and paid in full accounts. This I gleened from my conversation on the recent cli. Good Luck, as always, YMMV.
