Today when storing the suitcase in the cellar I suddenly realized, that the outside zipper compartment has two (!) zippers. As I newer checked that before I looked for the shopping bag only in the compartment I knew. Obviously I used the other compartment when I loaded the bag into the suitcase while the suitcase itself was lying in the trunk of my rental car - and the unusual position made me use the unusual zipper
SORRY to TSA, LH and everybody else who I blamed! It was only my fault - the bag is there!
