You get to use the First Class check-in line, no card is needed. They can see your status in the system. From there, I usually get the tags. I've had a pretty bad hit rate with priority tags with the kiosks. The biggest benefit is that your bags will make it on in case the flight is weight restricted. With oversize items like Golf Bags, your items may still be the last ones out, or in a separate area.
