This is a great card, highly recommended. I have the more expensive Signature version, which I find worth it. For example, through the end of the year there's a 25% discount at many Hilton Hotels off their regular website pricing when using the Signature.

As a big-time Southwest user, it's my primary card until I approach 100 credits in a 12-month period (the highest tier on Southwest), at which point I switch to the Hilton Surpass.
