WOW!!! This is a disturbing post. So if you have churned through 36 cards. At 5 points a hard hit that would be a drop of 180 points on your credit score. So say if you started with a good score of 700 you would now be somewhere in the low 500's...a very poor score. I wouldn't even see how you would qualify for an airline card at this point as most require a very good to excellent score. You need to focus on repairing your credit and not on credit card offers. You might get a couple of free trips and say save $1K on some airfare, but when you go to get a mortage or a car loan you will be paying out tens of thousands more in interest because of the damage you have done to your credit. Sorry if I sound too preachy here, but you need to go to credit card rehab or somethin. Call Dr. Drew.
