Two week ago, my brother and I flew on CO EWR-DFW. When we went through security (not together-maybe a half dozen people between us and on different lines), we had our own New Jersey DL's on us for photo id's but had accidentally swapped boarding passes. When inspected by the TSA agents, neither of us were questioned at all. Granted we do have the same last name, but we have completely different first names and middle initials. They should have atleast asked "Who is David?" to my brother and asked me about my brother's name on "my" boarding pass. It was just an honest mistake on our part but they still didn't do their jobs checking to make sure we were who we said we were.

I know this isn't CO's fault at all, but its still a security issue that could have bad for EWR and CO if we were people with alternate motives (which we're not) than those just taking a weekend trip to Texas.
