I have had this card for 9 years. It's okay. I like that I can earn miles by making regular purchases. The other ways to earn miles don't do much for me. Information about redemption options on the website is hard to find. You'll find it if you're persistent but why should we have to work so hard.
There are better alternatives out there in terms of interest rate, award levels, annual fees and blackout dates. As I said, it's okay and I've had it long enough to look good on a credit report but if I were starting out, I might look elsewhere for a better deal.
