Do luggage tags actually protect your privacy?

Only partially. Tags with a covered flap or a slide-in card hide your details from a casual glance, which is what most privacy-flap designs are sold on. But community threads on r/travel point out that anyone determined to read the card can flip it open in seconds, so the real benefit is keeping your home address off public view, not true security. Many travelers list a phone or email only, skipping the home address entirely.
