Editing Codeshare agreement (section)

==Terminology==
Under a code sharing agreement, the airline that administers the flight (the one holding the operational permissions, airport slots and planning/controlling the flight and responsible for the [[Aircraft ground handling|ground handling]] services) is commonly called the ''operating [[airline|carrier]]'', often abbreviated OPE CXR, even though the IATA SSIM term "administrating carrier" is  more precise. The reason for this is that a third carrier may be involved, typically in the case that the airline originally planning to operate the flight needs to hire a subcontractor to operate the flight on their behalf (typically a wet lease, meaning an aircraft is leased with crew and all facilities to fly, commonly due to capacity limitations, technical problems etc.) In this case, the airline  carrying the passenger should be designated the operating carrier, since it is the one carrying the passengers/cargo.{{Citation needed|date=June 2023}}

When a flight is sold under several designators and flight numbers as described above, the one published by the "administrating carrier" is commonly called a "prime flight" (as opposed to a codeshare marketing flight).{{Citation needed|date=June 2023}}
