Security experts have identified several common habits at airports that they believe can be problematic. One habit is the use of self-service baggage check-in machines. While convenient for travelers who prefer to handle their own luggage, these machines often require multiple steps and can lead to delays in processing bags [1]. Another issue highlighted by security experts is the frequent use of airport food bins. These bins are frequently contaminated with germs and bacteria from previous passengers' items [2]. Additionally, carrying firearms through airports remains a contentious topic. Security personnel have strict guidelines for handling such items, but some travelers still attempt to bring them on board, which can cause unnecessary delays and complications.
Travelers who want to avoid these issues should consider using self-service machines more efficiently by pre-checking their bags online or at kiosks before arriving at the airport [1]. For food bins, security experts recommend avoiding contact with surfaces that may be contaminated. Instead, travelers might opt for a tray of fresh fruit and vegetables provided by airlines [2]. When it comes to firearms, security experts advise against bringing them on board unless absolutely necessary, as they are subject to strict regulations and can cause significant disruptions at airports [1].
