After reading all the raves about PenFed, I decided to join as a member (have military family and already a member with USAA too) and apply for the Platinum Rewards Visa Signature.... approved for a SL of $5,500! I know it's just over the minimum for a signature, but this is my biggest SL yet. With rebuilding for almost 2 years and keeping my CC apps fairly low until very recently, this is very exciting for me 
I've read everyone's posts about their 90 HP and decided to apply for their Premium Travel Rewards Amex as well, since I fly home very often and this has 5x points for flight purchases... but it went to pending for a loan officer. Womp, womp.
Still excited about my instant approval for the Platinum Rewards Sig!!
