Terrible! On a non-stop within Europe. Should have been a no-brainer. Was your wife able to spot the luggage tag as it was stuck onto her suitcase? Both MADison Wisconsin and MADeira often pop up when searching for MADrid. Could the agent have sent a bunch of bags astray simply by fat finger or not paying attention? And, your wife did fill out the lost luggage form at Barajas, right? Often the agent will fill it out for you if you do not speak Spanish. They are supposed to call you with updates. Best of luck!
