Check-in is a busy step with a few common hiccups. One frequent problem is poor-quality bag tags. Weak printers or bad label stock can cause faded bar codes or broken labels. If a scanner can’t read a tag, a bag might be delayed. To fix this, IATA recommends strict label-quality control: airlines monitor print quality (Recommended Solution S1) and use high-grade materials (S2). They also train staff to straighten and smooth tags so machines can read them (S4). Training (S5) and clear staff checklists help ensure each tag stays legible until it enters the system.
Another issue is lost or missing tags. Sometimes a passenger forgets to attach the tag, or it falls off. IATA suggests using barcode scanners at the check-in and transfer desks (S16) so staff can quickly see any untagged bags. In self-drop systems, passengers often generate the tag themselves, so airlines ensure the electronic registration goes through before letting the bag go on.
Data mistakes can also occur. For example, a tag might show the wrong flight or name. If an error is spotted (during HPBT checks, see below), agents must cancel the tag and print a new correct one. The IATA manual’s guidance for HPBT states: if a home-printed tag is illegible or doesn’t match the itinerary, staff should destroy it, cancel its reference in the system, and attach a normal tag (scribd.com).
Overweight and oversized bags are another common snarl. If a bag exceeds limits, passengers must pay an extra fee or remove items. Clear signage and agent explanations help avoid disputes. IATA solutions include setting clear cutoff times for accepting bags (Solution S12) so late, oversized check-ins don’t rush the system.
In summary, IATA’s “Recommended Solutions” cover most issues: checking label quality, using good adhesives, monitoring tag scanning (S7–S9), and training staff. By following these practices, airlines catch many errors at the counter and keep the baggage flow smooth.
