Ground handling
Ground handling covers the physical services an aircraft receives on the ramp: marshalling, towing, chocks, ground power, lavatory and water service, baggage loading, cleaning and de-icing, along with the passenger-facing services of the FBO or handling agent. On a charter invoice it appears as a per-visit fee, occasionally with separate line items for specific services, and costs vary hugely: a few hundred dollars at a US regional airport, several thousand at London Luton, Geneva or Dubai, and more where a full handling agent is compulsory. It is one of the fees most often omitted from headline quotes, so ask whether handling at all airports on your itinerary is included.
