Flight Support, or Ground Handling as it is often called, is an essential element of airline services but is generally not considered a core-function of an Airline or Freight organisation. Flight Support functions include all aspects of customer services and ramp operations.
Today, more airlines around the world are recognising it is in their interest to move away from non-core functions, especially people related services such as Ground Handling, Maintenance, Crewing, etc.
The aviation industry is undoubtedly the most highly regulated industry in terms of regulations and compliance with the many regulatory authorities. As airlines have many other important matters to deal with, they are recognising that by outsourcing Flight Support to the experts, they can focus on what they do best.
