Last flight we WERE to take (wife got sick while waiting for plane,) I had a bag of Southern Biscuit mix and some country ham in my bag, which we were taking to her brother's house. Both bag of country ham, and biscuit mix caused a problem. Country ham because on X-ray, it looked like explosives, and baking powder in biscuit mix set off explosive's alarm. After searching bag, it was cleared, but they took my shoes to check them for explosives. After about 30 minutes, they decided I was free to go. Only one problem, they had lost my shoes. Finally they found them and returned them to me. As we were waiting at the gate wife became SICK. Gate agent said to rebook later, as they didn't want her on plane throwing up. Ah such fun. FYI, two of our kids work for different airlines, so we fly nonrev status.
