If you’ve ever anxiously scanned the baggage carousel at the airport

you know the stress of finding your suitcase among a sea of similar-looking bags.

While many travelers attach colorful ribbons to their luggage to make it stand out

a Dublin Airport baggage handler warns against this common practice.

According to John, the baggage handler, “Ribbons that people tie onto their suitcases to help identify them can cause issues with the bag being scanned in the baggage hall.” He explains that if a bag can’t be scanned automatically, it may require manual processing, potentially causing delays and even missing your flight.

Another surprising tip: avoid packing marzipan. “Don’t ever pack marzipan in your luggage. It has the same density as some explosives,” John says, warning that this could lead to your bag being flagged for a security search.

Instead of using ribbons, consider choosing a suitcase in a bold color or adding fabric paint or stickers that won’t interfere with scanning. By following these tips, you can reduce the risk of airport mishaps and ensure your luggage arrives safely at your destination.
