释义 |
A fare basis code (often just referred to as a fare basis) is an alphabetic or alpha-numeric code used by airlines to identify a fare type and allow airline staff and travel agents to find the rules applicable to that fare. Although airlines now set their own fare basis codes, there are some patterns that have evolved over the years and may still be in use. Fare codes start with a letter called a booking class (indicating travel class among other things) which almost always matches the letter code that the reservation is booked in.[1] Other letters or numbers may follow. Typically a fare basis will be 3 to 7 characters long,[2] but can be up to 8.[1] Booking classThe first character of the fare basis code is always a letter, and will almost always match the booking class.[3] Booking codes are the identifiers used by the airline's revenue management department to control how many seats can be sold at a particular fare level. For example, a plane may have 25 economy seats still available and the airline may show it in a reservation system as Booking codes were defined by IATA,{{cn|date=February 2018}} but airlines have deviated from the IATA standard and current booking codes are airline-specific.[4] The same code may have different meanings for tickets issued by different airlines. Many airlines use nearly all letters of the alphabet to allow finer yield management. Nevertheless, certain booking codes have retained the same meaning across most airlines:
Other common patternsLetters and numbers in other sections of the fare basis code may provide the following information:
Airline-specific codesThere is an endless list of other codes on modern fares. These are not standardized in any way, and may often be for short-term use. The following are some examples:
Fare constructionFare construction refers to the application of fares which can cover the flights in the reservation, necessary to price the air ticket for issuance. It is commonly presented as a single line with standardized codes[7] which can be used for travel agents to price the ticket in global distribution systems. For example, a fare construction may say:
Fare construction is a complicated task because each fare comes with a lot of rules regarding the usage, however the rules are designed to be validatable by computers so the system can decide to accept or reject easily. Most commonly fare construction is done by a computer automatically, but it is not guaranteed that the lowest fares can be found, therefore manual fare construction can also be done, which means finding the suitable fares manually and applying the fares to an itinerary in order to buy a ticket. Multiple fare basisIt is common for a multi-sector air ticket to have more than one fare basis, particularly if it is for carriage on more than one airline, or different classes of travel are involved. The issuing airline may often have an interline agreement to allow other airlines on the ticket. One disadvantage of this system is that if any change is made, the most restrictive fare rule, and/or the highest change fee, may apply to the entire ticket, not just the portion being changed.[8] Global Distribution SystemsIn a Global Distribution System, the fare basis will typically display as part of a fare display, and will not normally be shown in an availability display. Some modern booking systems allow availability searches using parameters such as time of day and lowest fare, and may negate the need for an agent to firstly study the fare basis rules. TicketsThe fare basis is normally shown on the air ticket. On older paper tickets, it was highlighted on the relevant coupon for that flight. On modern e-tickets, it is often printed under the flight details.
