A friend of ours left his iphone on a B.A. Flight coming in from the States. He realised he had left it as soon as he got into the Airport and told stafff, of course he could not go back, but he asked if staff would bring it to him. Nothing happened when he returned to his house he made lots of enquiries and no one had found the iphone. However, iphone replaced his phone under an insurance he had with them.
Bernie, if you don't get your ipad back, check your insurance.
