Locks on zippered suitcases are useless.

According to user royalsiblings, "You can pop a zipper with a pen and drag the locked zipper pulls around the bag to close them back up. I've done this many times to identify bags that are tagless and locked. Exactly like this."

Bring your own headphones.

“I used to work for warehouse that supplied a certain airline with items. The headsets that are given to you are not new, despite being wrapped up. They are taken off the flight, “cleaned”, and then packaged again,” said Reddit user ichigo29.

Remove old flight tags.

“Not a secret, just common sense; the reason some bags miss their flight or get misrouted is because passengers don't remove old tags. It confuses handlers as well as the conveyor belt scanners. I see it happen all the time,” said Redditor –aurelius.
