Thanks. I've got some names. I am planning to fly US to CDG, transit CDG and arrive at AMS. My concern would be less if those were not the airports involved. (I am transiting LHR on the return, but am less concerned about late bags on the return.) Also, I often now use Apple airtags, but those only let you know where the bag is. They do not help much in making the airline handle it timely or deliver it faster.
