Glad you got it back.
My wife left her iPad on an AA flight a few years ago when we were living in Denver. She only discovered it 3 days later. Using the Lost my iPhone app, it showed up as being in an AA office across from Gate 43 in the A concourse at DEN. So I called a contact I had at the DEN Admirals Club. The agent called back to report that nothing had been reported and no one on the A concourse office knew anything about it. But 10 minutes later, I saw the iPad on the move, leaving the terminal and then winding up in the employee parking lot. As soon as it stopped moving, I triggered the alarm button. For those that have tested this, the iPad alarm is ear piercing and lasts a good 30 seconds. Right after that, the iPad was on the move again, back to the terminal. 15 minutes later, I got a call from AA Baggage service informing me that they'd found the iPad. I drove out to DIA and picked it up later that day.
