About a year ago I tried using my CHL at Hobby airport, just to see if they would accept it. The TSA checker was very nice, and said that it would be accepted as a secondary form of ID, if the primary (driver's license, passport, etc) were not available. He said because of all the varying requirements by the different states for CHL, they didn't accept Texas CHL as the first form of ID.

A different time, I was checking in at San Antonio airport and was without my driver's license (long story, and before I got my CHL). I went to the AA ticket counter first, and explained my situation. The ticket counter lady printed a special boarding pass, took me to the TSA agent, and they accepted my work photo ID, a ATM card with my name printed, and my vehicle insurance card with my name on it. Probably added abut 5 minutes total to my processing time.
