Filing advice number

Flight-related services

An optional service that must be associated to a specific flights on a passenger's ticket. For example, a service for advance seat assignment.


Abbreviations for footnote.


Alpha, numeric, alphanumeric, or numeric-alpha characters appended to a fare record indicating specific conditions applicable to the fare. Used along with categories to further restrict a fare, footnotes usually contain travel dates, sales dates, or other special conditions. An advantage of coding restrictions in a footnote rather than a rule is that a footnote may reside in any fare within its carrier/tariff. Any number 1-99 and any letter other than F and T may be assigned to the footnote. (F and T are reserved to mean "travel must be FROM/TO the first city shown in a given market" when they are coded in Category 23.)


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


The last point of departure or first point of arrival within a geographic locale as specified below: (Note there is an implied hierarchy in the following descriptions.) a. When traveling between Areas 1, 2, or 3, the last point of departure/first point of arrival in that area. b. When traveling between zones within an area, the last point of departure/first point of arrival in that zone (not applicable to travel between zones within the United States). c. When traveling between countries within a zone, the last point of departure in one country and the first point arrival in another country. NOTE: Gateway hierarchy applies to fare components or pricing units depending upon category application. When travel crosses multiple IATA areas, such as NYC--BOM via PAR(Area 1 to Area 3 via Area 2), the departure from Area 1 (NYC) and the arrival in Area 3 (BOM) are considered the gateways. The intermediate via points in Area 2 are not (PAR), unless further modified by a Gateway TSI in combination with Geographic Location (such as Gateway Europe).


Great circle miles.

General rule

Restrictions that apply to all fares; consequently, they are separate from the individual fare rules. When a general rule does not apply to a fare, the non-applicability is included in the fare rule. Also called governing rule.

General Rules

Printed tariff pages that are published as legal documents for the governments of Canada and the United States.

Gross fare amount

A filed published or private fare (the amount shown in the Base Fare Box of the passenger coupon). Also called ticketed fare amount.

Gross reporting amount

The amount reported to the carrier by the agent, including any commissions to be deducted through the ARC/BSP return.

Half-round-trip fare

1. (US/CA fares) Half of a round-trip fare. A one-way fare is never considered a half-round-trip fare. See also combinations. 2. (International fares) Half of a round-trip (Tag 2) fare or a one-way (Tag 1) fare doubled and halved. Half of a specified/published or constructed/unpublished round trip normal or special fare. Additionally, the one-way normal may be considered to be a half-round-trip normal fare. If a one-way special fare may be doubled to establish a round-trip special fare, the one-way special fare may be considered to be a half-round-trip special fare. A one-way Tag 1 fare doubled and halved may be considered to be a half-round trip-fare, but it is never considered to be a Tag 2 fare. A half-round-trip fare is never a one-way (Tag 3) fare that cannot be doubled. See also combinations.

Headline city

The city that appears first in a market city pair. Also called origin city.
