I was trying to add one more tradeline so I bit the bullet after researching and applied for the US Airways CC. I got a denial letter via email that said, "we based our decision on your credit score which was not high enough to qualify." They ran my TU score which is 643. Not good but I saw that they approved many others here in the same range?
