Access from the ticket counters is up the escalators that are more-or-less in the center of the ticket counter/check-in area, then a long walk to the east (you're actually crossing the road below) followed by a right-turn and a long walk to the south (the baggage claim area is below and on your left at this point).

Somebody somewhere in another thread had commented that the TSA clerks often have the chain/gates closed-off and have to manually allow people thru to access the C gates after clearing this Checkpoint.

Access to the other/newer Checkpoint for the C (and A/B) gates is way down at the far south end of the Southwest ticket counters (to your left as you face the counters) and up a shorter escalator. This is where the elite line/employee line is on the left (essentially at the top of the escalators) and I noticed the clerks had their fancy new podium-attached scanners (although not in-use Sunday).
