Many travellers worldwide tie a bright ribbon, bandana or other personal marker to their suitcase handle so their luggage is easy to spot on the carousel. It feels harmless — a small trick to make a black or navy suitcase stand out from the sea of similar bags. But according to several recent travel‑industry reports, baggage handlers (for example one who works at Dublin Airport, referred to as “John”) warn that these personalized accessories can create far more problems than they solve.

From the handler’s viewpoint, the ribbon or tag may snag on machinery, obscure or cover the bag’s barcode or RFID tag, or otherwise interfere with automated scanning and sorting systems.   Because modern baggage‑handling depends heavily on scanners reading barcodes (or similar identifiers) at multiple stages — check-in, sorting, loading, arrival — any obstruction can force the bag into manual processing. That extra step can result in delays or even cause the luggage to miss the flight.

According to handler “John,” when a bag with a dangling ribbon or decoration enters the conveyor and scan‑area, the ribbon might cover, obscure, or reflect over the barcode/ID tag. This prevents the scanner from automatically reading the tag. In such cases, the system cannot confirm routing or flight assignment, so the bag is flagged for manual intervention.

Once a bag is diverted for manual processing, airport staff have to locate the tag, read it manually, and re-enter the information — a slower, error‑prone process. This increases the risk the bag will be mis‑routed or simply not loaded onto the intended flight. Handlers have repeatedly cautioned that this modest decorative habit can unintentionally create real travel‑disrupting consequences.

The problem is not limited to ribbons. According to the same handler warnings, old travel stickers, expired tags, or other labels stuck on a suitcase can confuse scanners — whether by creating ambiguity about which tag is current or by blocking barcode visibility. Many experts recommend clearing off all old stickers before checking in a bag.

Furthermore, some substances packed in checked luggage may trigger security or scanning alerts. One example often cited: Marzipan (a dense almond‑based treat). The density and composition of marzipan may cause scanners to resemble certain prohibited materials, prompting security to remove the bag for manual inspection — delaying the baggage or even triggering additional scrutiny.

These additional factors mean that luggage problems aren’t always due to negligence by the airport — sometimes travellers’ choices contribute inadvertently.

While many of these warnings come from individual handler testimonies or media‑reported advisories, broader data on baggage mishandling helps situate the problem in context. According to a recent industry report on baggage handling trends published by SITA (2025 Baggage Insights), the largest source of mishandled bags globally is not scanner issues per se, but transfers — difficulty moving bags correctly between flights.

Scanners or tagging errors do appear among other causes (ticketing errors, loading failure, security issues, and bottle‑necks in handling) — but scanner‑related delays constitute a smaller portion of overall baggage problems.

That said, because scanner‑failures tend to disproportionately affect certain types of baggage (e.g. those with decorations or non‑standard tags), the warnings remain relevant. Even if scanner disruptions don’t represent the majority of mishandlings, they pose a real risk for the subset of bags that violate optimal tagging/marking conditions.

Given what’s known, many baggage handlers and travel‑advice sources recommend avoiding ribbons, dangling tags, dangling accessories, or non‑standard decorations on checked luggage. Instead, travellers should:

• Choose suitcases in distinctive colors, patterns, or designs — bright or unique hard‑shell or soft‑sided luggage stands out without interfering with scanning.

• Remove all old stickers or expired tags from previous trips, to prevent confusion or mis‑routing.

• Keep the barcode/ID tag visible and unobstructed. If you use a tag, make sure it’s affixed properly to a stable handle rather than dangling loosely.

• If possible, travel with carry‑on or minimal risk items; dense or irregular items (like marzipan or bulky perishables) may trigger security scans and delays.

These small adjustments can reduce the chance that luggage will get flagged, rerouted, or delayed — especially during busy travel periods when scanners and sorting systems are under heavy load.

Your narrative — the idea that something as harmless as a ribbon can trigger a cascade of complications — shines a light on how fragile and complex modern airport baggage‑handling systems really are. On the surface, tying a ribbon feels like a simple organizational trick. But behind the scenes, each bag moves through a chain of automation, machines, scanning stations, and human handlers. The system relies on accurate tagging, clear visibility, and smooth transitions; anything out of the ordinary can throw everything off.

Although large‑scale data suggest that scanner failures are not the leading cause of lost baggage overall, the examples from handlers and media show that for individual travellers, small personal choices can make a big difference. What seems unlikely — a bag missing a flight — can become plausible when a barcode is obscured or the bag needs manual reprocessing.
