February 18th my son and I were flying back for Las Vegas to Atlanta on DL 1356. The plan was full so we decided to be nice and check our bag and not do carry on. upon arrival to Atlanta we proceeded to baggage claim. We got our bags on the turn stile and my bag had the front zipper pockets half open. I made a quick check and everything appeared OK. After getting home, I started to un pack and noticed my watch was missing. It was a blue Hook and Gaff watch valued at over $350.00 and was just purchased a month ago. I continued to go through my main compartment and it looked like someone had gone through it also. It was very messy. Delta, please do not ask me to ever check a bag again.
