Part Charter - Where part of an airline's scheduled flight is sold as if it were a charter in its own right. Often incorrectly used as a synonym for split charter.
Part Load Charter - Where a part of an aircraft's load is discharged at one destination and a part of it at another. This is distinct from a split charter where a number of consignments are carried to the same destination. Inbound, part loads are treated as single entity charters under the regulations in most countries.
