Glossary

Stumped by industry jargon? Here are the definitions and
explanations to make it all clear.

Data application

The industry-endorsed processing laws that apply to ATPCO data for itinerary pricing solutions. Data Application creates an industry standard aligning ATPCO, data providers, and data subscribers for consistent industry-wide itinerary pricing.

Data Distribution (G30)

Directory that controls which organizations (subscribers) receive what public and private data from ATPCO for processing. Now replaced by the FareManager Distribution application.

Data owner

The carrier who owns the fare products.

Data provider

The organization that contracts with ATPCO to file fares, rules, and other data in its own files under its own control.

Data table

A table used to house rule provisions in the FareManager Rules system. See also Record 3.

Data table set

A series of data tables within the string between a THEN data table to the next THEN data table or ELSE data table.

Data table string

A series of 1 to 200 data table numbers and the relational indicators contained on the recurring segment of the Record 2.

Data table subset

A series of data tables in a string that can stand alone to validate the fare component. Generally this is equal to one Record 3 table when tables are strung with OR. It can also be a group of tables which constitute a unit of thought when there is an AND relational indicator. Subsets include the following situations: THEN, AND THEN (when the next table is OR and there is no 'If' condition) THEN, IF THEN, AND, IF THEN, IF, AND THEN, AND, IF, AND ELSE, AND OR ELSE

DCS

Departure control system.

Decision support

See fare management.

Departure control system

An airline IT application that manages Check-In/Boarding and Load Control for airlines at airport locations. Checked baggage, optional services, reissues, refunds, and even fare/rule data are instances where ATPCO data is used in these applications.

Destination

Ultimate stopping place of the journey as shown on the ticket. When the word destination is used in a fare rule, general rule, or Rule 2, it will be necessary to determine the carrier's own definition.

Direct channel

The process of pricing and booking tickets within an airline's own internal environment, without using pricing systems or other intermediated industry data. This is most commonly handled through a carrier's website, but may also be done via a call center or at airport/city ticket offices.

Direct connect

See direct channel.

Directional fare

Fares that are published with a directional indicator (either on the fare record or footnote). Directional fares are usually international. See inbound and outbound.

Directional indicator

A tag that determines the true origin and destination of a fare or application of supporting text. This allows data to be stored most efficiently and displays the data in its true order (from point A to point B or vice versa).

Directionality

A tag used on the Record 1 or 2 to indicate that that Record 3 provision applies in a certain direction only.

Directionality tag 1

A tag used on the Record 1 or 2 to indicate that the Record 3 provision applies from Location 1 to Location 2.

Directionality tag 2

A tag used on the Record 1 or 2 to indicate that the Record 3 provision applies from Location 2 to Location 1.

Directionality tag 3

A tag used on the Record 1 or 2 to indicate that the Record 3 provision applies for travel originating in Location 1.

Directionality tag 4

A tag used on the Record 1 or 2 to indicate that the Record 3 provision applies for travel originating in Location 2.

Discounted passenger

The passenger travelling at a discounted fare that requires another full-fare passenger. Also referred to as accompanied passenger.

DISH

Data Interchange Standards Handbook, the definitive guide of file standards and specifications for the BSP HOT file.

DOT

Dynamic price adjustment

A dynamic pricing method where the system selects a price from a pre-defined menu of possible price points. Then, for certain customers or in certain situations, this price is adjusted through either a discount or an increment. All adjustments are made in reference to a price from the fixed menu, and some customers are shown an unadjusted price.

Dynamic pricing

The methodology that is used in the airline industry to set the price that most closely matches the marketplace conditions at the time of the product offer.
