Glossary for the airline industry

From A-Z, this glossary covers definitions and explanations for common airline industry terminology.


A piece of standards work that involves a change in processing by at least one of the consumers of the standard.

equipment code

A three-character IATA-managed designator indicating which type of aircraft is used on a particular flight. Although most commonly found in Schedule Data, these codes also exist in Rule and Service Fee provisions.


European Union Payment Services Directive II. A European Commission mandate that requires between not only personal and corporate cards, but also between cards issued inside or outside the European Economic Area (EEA). EU-PSD II will prohibit surcharges on consumer credit/debit cards issued inside the EEA.


According to IATA Resolution 017f, an exchange is a change to the carrier, flight, date, class of service or sector of the first flight coupon. The new fare shall be calculated from origin to destination of the new journey based on the fares applicable at the time of commencement of the new transportation (that is, using current fares). See also reissue.

1. The charge for a passenger to fly from origin to destination. 2. The amount a passenger pays, including the conditions for travel at this amount (that is, the rules and restrictions that must be satisfied in order to qualify for a specific fare). Together, fares and rules form an infrastructure used for autopricing (identifying a fare electronically). A fare has 11 components: including market (city pair), rule number, fare class, one-way/round-trip indicator, MPM or routing number, footnote (optional), currency, fare amount, effective date, discontinue date, and mileage. Also called ATPCO fare record. 3. The published tariff fare amount. 4. The charge for a passenger to fly a given segment (city pair). See also fare basis code, domestic US/CA fare, international fare.

fare basis code

The Fare Basis is the code that appears on the ticket in the Fare Basis box. It can include letters, numbers, and up to two slashes (/). A Fare Basis is a compilation of the fare class or ticketing code and one or two ticketing designators. The fare basis code should not be confused with the fare class, which is associated to each fare and is used in pricing. Also called fare basis.

fare break point

1. The destination where a given fare begins or ends.

2. (data application) Terminal points of a fare component. Also called fare construction points.

3. A stopover which can only be made upon payment of the sum of the local fares between that point and the preceding and successful fare construction points.

Fare By Rule

The creation of new fares by a pricing system using rule data to specify the fare markets and amounts. The fares can either be calculated from existing fares in the market or specified to create a new fare using the rule provisions coded in Category 25.

fare class

The one- to eight-character identification of the fare.

Fare Class Application

An ATPCO record involving an Automated Rules Tariff, Carrier, Rule Number, Fare Class, Sequence, and Effective date combination. The Fare Class Application record provides miscellaneous data (such as fare type, ticketing codes, and passenger type) pertinent to the specified fare class that is necessary for pricing and assigns the reservation booking designators required to qualify for the fare. Also called Record 1 or Fare Class Record.

fare class record

See Fare Class Application.

fare component

A portion of a journey or itinerary between two consecutive fare break points.

fare construction point

See fare break point.

Fare Creator Table

The Fare Creator Table 979 is located in Category 35 Record 3. Table 979 provides fare calculation information to create either net or selling amounts from the starting fare. Selling amounts can be specified, calculated, or expressed as ranges. Net amounts can be specified or calculated.

fare family

A method of identifying multiple fare classes in a single entry. In the Category ID, the Fare Class field can be coded with a hyphen to mean all fare classes that contain these characters.

fare management

The act of maintaining and updating fare products (fares, rules, etc.). See also offer management. 2. The business decisions behind creating, modifying, or canceling fare, rule, and other records in order to support complex pricing. Fare management presents both historical and current market fare and rule data that airlines query and use to make changes. This process occurs concurrent to yield management, although most large carriers usually have different departments for these two processes. Also called decision support (industry).
