Found brown leather suitcase outside baggage claim at San Antonio International Airport with travel stickers but no visible ID.

I found a brown leather suitcase just outside the baggage claim area of the San Antonio International Airport yesterday afternoon. It looks like it belongs to someone who travels often, as it has a couple of travel stickers from different countries on it. I opened it briefly to look for identification, but there was none visible. I want to make sure it gets back to its owner!
