You might be on to something…
What puzzles me the most is… if he picks-up luggage that is not his, what happened to his own, actual luggage?
Did he pick up his own luggage AND another that is not his?
Does he travel without any luggage?
Because if he picked-up luggage not his by accident, his actual luggage would have been left there at the luggage carousel going round and round and round, and the airport would have it as abandoned luggage, and it would lead them directly to him, if it were properly tagged, etc…
WEIRD.
