ancillary services
Additional products and services offered to travel customers during the booking process
Ancillary prices can be bundled or unbundled
Unbundled ancillaries (a.k.a., “air extras”) are not included in the published base fare

B

base fare

basic connection
The simplest approach for consuming Sabre APIs. A connection is established using the SessionCreateRQ Service, and after one or more services is consumed, the connection is closed using the SessionCloseRQ service.
booked fare
A fare that is associated with a booking but it is not yet ticketed
booking
The air booking volume "booked" via the Sabre GDS.
booking class of service
The fare category. Usually, each flight consists of multiple classes, categories of fares, or fare inventory. A booking class of service code is the code for the fare category.
The booking class of service is not the same as the flight class of service, such as first class and economy class.

C

cache
In computing, a cache is a component that stores data so future requests for that data can be served faster.
client
The computer application initiating a service request in a client-server model
Client ID

See also operating airline.
city pair

connecting flight

connecting flight
A flight that requires a passenger to change planes at an intermediate airport, between the departure and destination airports
codeshare agreement
An agreement between two airlines in which the marketing airline puts its own airline identification code on flights that the other participating airline actually operates. Suppose that U.S. Airways and United Airlines have a codeshare agreement. U.S. Airways, the operating airline, operates a specific flight, and United markets, sells, and collects payment for the flight. United Airlines, called the marketing airline, displays its own 2-letter code next to the flights on a consumer website. For more information about codeshare agreements and regulations, visit http://www.gsa.gov/portal/content/103887. 
connection
A channel to the Sabre APIs infrastructure that is opened after a client or other process requests authentication and is authorized

disclosure airline
For airline companies that have a code sharing agreement, the airline that operates the flight. See operating airline and codeshare agreement.
divide in party
On multiple passenger requests, if passenger types require different booking codes for the lowest fare, they must be booked in different Passenger Name Records (PNRs). For example, if the ADT passenger type must be booked in Q and the CHD passenger type must be booked in V, they cannot be booked in the same PNR. This requires two separate PNRs, otherwise known as Divide in Party.
domestic
A destination located in the same country as the origin.

E

electronic miscellaneous documents (EMDs)
Provide the capability to issue electronic non-flight vouchers for purchase of various travel services - such as fulfillment of ancillary services

equivalent fare
The amount of the inventory or base fare in the payable currency, excluding taxes and fees
elapsed time
The total time for a flight on a flight itinerary. The time is calculated from the date-time of departure to the date-time of arrival of a flight. A service or API can calculate elapsed time for either a flight leg or every flight segment within a flight leg, or both.
Elapsed time on each flight segment within a flight leg begins with the date-time of departure of a flight segment through the arrival date-time of the flight segment.
Elapsed time on a flight leg begins with the date-time of departure of the first flight segment through the date-time of arrival of the last flight segment in the flight leg, and it includes all time in between the first and last segments.
The InstaFlights Search API returns elapsed time in minutes. Elapsed time is also referred to as travel time or total travel time.
