just like the secret pathways through the forest that only we rangers know, some parts of the airport operations are classified, kept away from the public eye to ensure everyone's safety. before you embark on your journey through the vast wilderness of terminals and runways, it's essential to have a prearrival briefing. this is where you learn what to cut out of your luggage to make your trek through security as smooth as a mountain stream. sometimes, we all need a reset, a moment to recalibrate our internal compasses, much like the way airports function silently behind the scenes, guiding you safely to your destination without revealing all its secrets.
