Considering how late my first flight was, and how just-barely I made it to my second flight (which was delayed for those of us with late connecting flights) it wasn't that surprising the bag didn't make the connection.
The call from US Airways at 9:30 am to say my bag had arrived was a bit early, considering it felt like 6:30 am, but that's not their fault.
Already gave Alex back the spare key. Ya never know when it might come in handy again.
