Working at an airport requires a diverse set of skills depending on whether you are in ground operations, security, or customer service, but all roles share a foundation in aviation safety and security protocols. You must first learn the "Airside vs. Landside" distinction and master the strict regulations set by authorities like the TSA or CAA, including the handling of prohibited items and emergency evacuation procedures. For customer-facing roles, you need to learn how to use a Global Distribution System (GDS) like Amadeus or Sabre to manage flight bookings and check-ins.
