Air Glossary
-
Exchange situation in which additional payment is due for the exchanged item, such as the itinerary or a paid seat.
-
Any paid optional service filed for a flight. Industry examples include paid seats, paid baggage, carbon offsets, pet transport fees, and unaccompanied minor charges. See the Ancillary and EMD Guide for supported ancillaries.
-
Airline Tariff Publishing Company, a company that collects and distributes fare data for the airline and travel industry.
-
A refund that is processed entirely within the JSON APIs, from requesting a quote for the refund and any penalties through processing the cancellation. In the JSON APIs, NDC refunds are supported while GDS refunds are under development.
-
In a Search response, the lowest price available for combining two products (a product is one leg of the itinerary). Products that are combinable at the lowest fares have the same CombinabilityCode. For example, if p6 on the outbound leg and p24 on the inbound leg share a CombinabilityCode value of j2, both products return the same BestCombinablePrice, which lists the base fare, taxes, and total price for the combined itinerary. If more than two products have the same CombinabilityCode, then any outbound/inbound combination of those products can be combined at the same price. See the Air Shopping Guide for more details.
-
A confirmed reservation with the carrier. A held booking is a reservation that has not yet been ticketed. The terms booking and reservation are interchangeable.
-
An upgrade from the base fare that includes certain features in the price, such as wifi or seat selection. Features included in a brand are specified in the brand attributes (BrandAttributes object).
-
A service included in the branded fare, such as wifi or a free checked bag.
-
Airfare with certain features included in the price; for example, a seat assignment and wifi at no extra charge.
-
An air offer that is combined with an ancillary. Not currently available for booking in the JSON APIs; returned only in the Search response for specific NDC carriers.
-
Cancel a ticket outside the void period without rebooking on another itinerary. Depending on the airline ticket policy, canceling a ticket may result in a full, partial, or no refund.
-
An airline.

API call that ends a workbench session, finalizing all changes and requests in that session. Depending on the workbench transactions, the commit workbench request may create a reservation, issue a ticket or EMD, exchange tickets, or modify a reservation.
-
A change to a different airplane on the way to the destination.
-
The city where travel begins. Also called the origin.
-
Document instruction (DI) lines in the booking record contain information such as price, flight information, confirmation, ticketing time limits, fees, and form of payment. Not returned as DI lines in the JSON APIs but available through a desktop program.
-
Electronic miscellaneous document (EMD); issued for a paid seat, ancillary, or any other paid service after successful payment. See the Ancillary and EMD Guide.
-
Cancel or modify a ticketed itinerary and issue a new ticket. See the Cancel, Exchange, and Refund Options Guide.

See the Fare Rules Guide for details and supported formats.
-
The Flight Specific Search API retrieves any additional upsells available for a selected flight.

Details for the payment to be used to pay for an offer, such as credit card information. The subsequent Add Payment step is required to charge the payment.
-
In the JSON APIs, an API call that sends all details of the flight/s to be shopped, priced, added to the workbench, etc. instead of sending a reference to an identifer for an offer or product in a previous API response.
-

-
International Air Transportation Association, an organization that standardizes rules, regulations and fare construction principles for the international travel industry.
-
The JSON APIs use multiple identifiers: for offers, products, segments, and the response as whole. These are used to cross-reference information in the same response, or referred to in subsequent requests so that ful details are not required to be sent in a follow-on request. See the JSON APIs Guide.
-
An optional workflow in which the booking is made and ticketed in the same workbench session. NDC only; not supported for GDS.
-
A cancellation and refund initiated by the airline, such as when a flight is canceled and the passenger cannot be rebooked. The JSON APIs do not support involuntary refunds.
-
The entire trip on a booking, including all flights on all legs. Also called a journey.
-
A Search that returns offers for all legs on the itinerary. A journey-based Search request is a standalone search. No additional search requests are required. See leg-based below.
-
A modifier that refines the API request based on travel criteria and not the fare, such as searching by carriers, connection times, and/or cabin classes; sent in the SearchModifiersAir object. See the Air Shopping Guide for a list.
-
The flight or connecting flights between one origin and destination pair. For example, on a round-trip flight, LAX > MSP could be the first leg (aka outbound leg) and MSP > DEN > LAX could be the second leg (aka inbound leg). The JSON APIs use the term product (see below) to represent one leg of the itinerary.
-
A Search that returns offers for only the first leg of the itinerary. Must be followed by a Next Leg Search request that selects an offer for the first leg and returns offers to combine with that leg. A multi-city itinerary requires another Next Leg Search for the third leg. See the Air Shopping Guide for details. See journey-based above.
-
A refund in which details about the refund amount and any penalties are obtained from a source other than the JSON APIs and the JSON APIs are used only to process the cancellation. The JSON APIs do not support manual refunds.

New Distribution Capability, an XML standard for exchanging data that supports airlines in distributing their content directly to online travel agencies. See the NDC Guide.
-
Net fares are consolidator fares, or any negotiated wholesale price that is further marked up for sale to customers. GDS only; not offered by NDC carriers.
-
The Next Leg Search request is sent after a leg-based Search request to return offers on the subsequent leg of the itinerary.
-
Origin and destination (O&D) pair, or one leg of an itinerary. In the JSON APIs, product is the term for the flight/s on one leg.
-
In the JSON Search APIs, an offer is a product available at a specific price under a set of terms and conditions. A product is the flight or connecting flights for one leg of the itinerary, plus a service level that includes the cabin class and any fare codes that may apply. At booking, the selected offer from the Search response - including the flight/s, service level, price, terms and conditions, and brand if applicable - is converted into a single Offer object that is subsequently returned for that booking.
-
An itinerary with a single destination; e.g., LHR > CDG.
-
Itinerary where the departure city is not the same as the return city, or the arrival city is not the same as the return departure city; e.g., LHR > CDG and AMS > LHR.
-
Pseudo city code. A travel provider's identification code for the JSON APIs, provisioned from Travelport. Used to determine access and other settings in the JSON APIs for your company.
-
Passenger Name Record. Unique six-digit alphanumeric number that identifies a booking, e.g. JS7GH4. Sometimes used to refer to the booking record itself. Because the term PNR is specific to GDS, this online help uses the more generic term "reservation locator".
-
Point of sale. The location at which a booking is made or a ticket issued. The POS location may determine the taxes, fees, time to ticket, and other restrictions on a ticket.
-
Refers to the state of a booking after the booking is created, which happens after the initial booking workbench is commited and the reservation locator code issued.
-
A modifier that refines the API request based on fare and ticketing options and not the travel itself; sent in the PricingModifiersAir object. See the Air Shopping Guide for a list.

-
In the JSON APIs, a product is the term in the code for one leg of the itinerary, plus a service level that includes the cabin class and any fare codes that may apply. A product includes the flight or connecting flights between one origin and destination pair; e.g., LON > EWR.
-
Passenger Type Code, used to categorize travelers. The most common PTCs are adult (ADT), child (CNN), and infant (INF). You can request a maximum of 9 passengers in one Search request.
-
A published fare available to all consumers without an account or corporate code.
-
In the JSON APIs, an API call that sends identifers referring to a previous response for the itinerary to be shopped, priced, added, etc. instead of full itinerary details.
-
Unique six-character alphanumeric code returned for a successful booking, e.g. JS7GH4. For NDC the airline returns an additional locator code, which can be called the vendor locator code. Sometimes called a PNR and used to refer to the booking record as a whole, but because the term PNR is specific to GDS, this online help uses the more generic terms "booking" for the booking record and "reservation locator" for the six-character code.
-
Created for bookings that fail due to inability to either add the offer or quote a fare. Includes traveler details to allow agency to complete the booking as necessary. For a reservation shell to be created, the autoDeleteDate query parameter must be sent at the workbench commit.
-
An itinerary in which travel goes to a single destination and returns to the origin. E.g., LHR > CDG and CDG > LHR.
-

These identifiers must often be sent in subsequent requests to refer to a previous response, offer, product, etc. Usually returned in Identifier/value for the referenced object. Example format: 3cecf1be-0b21-4881-8f33-ae11c8d7b708. See the JSON APIs Guide.
-
A tracking id returned in the transactionId object under the first top-level object of every response in the JSON APIs. This system-generated ID assists Travelport and customers with troubleshooting if needed. In addition, developers can send a custom traceId in the header as their own tracking number. See Transaction and Trace IDs on the General menu.
-
A fare presented along with the base fare as a higher level of service, usually a branded fare. Returned if filed by the carrier and requested with maxNumberOfUpsellsToReturn in the Search request.
-
