John also shares a lesser-known tip regarding certain items packed inside checked baggage. Dense foods—especially marzipan, nougat, and some types of chocolates—can resemble restricted materials on security scanners because of their density. This similarity occasionally triggers additional inspections, which may slow down the screening process. Travelers who plan to bring these items home as gifts or souvenirs may find it easier to pack them in their carry-on luggage or send them separately to avoid potential delays. These simple choices can help ensure that both passengers and airport security staff experience a smoother, more efficient workflow.

To make luggage easy to recognize without risking disruptions, John recommends choosing bags in distinctive colors or adding secure, non-dangling identifiers such as brightly colored tape, painted markings, or sturdy built-in features.
