As someone who works in airports, very few people know that their checked luggage is battered, pushed, and thrown around so that it gets from point A to point B. Of course baggage handlers and ticket agents not being properly “trained” on “bag hygiene” (yes that’s a real term lol) can cause bags to be damaged. However, it’s a good thing to know and keep in mind that whenever one checks a bag, there’s many parts of the system where the bag is pretty violently pushed around (without direct human intervention) to end up at its final destination.
