Low Fare Shopping functionality combines air availability and a fare quote request to return the lowest available fares for a specified itinerary, using origin/destination and date information. Fares are available for one-way, round-trip, and multi-city travel. Low Fare Shopping does not require a booked itinerary to return fare data. Low Fare Shopping serves as a fare shopper tool for users who want to check prices for a general itinerary. It is best suited for fare-driven travelers.
A number of modifiers can be added to the Low Fare Shopping request to return specified responses. These modifiers include time period, included or excluded carriers, private fare modifiers, and passenger types.
Low Fare Shopping responses may contain basic details for Branded fares by default, when available. Details for Upsell fares must be requested specifically in the Low Fare Shopping and Asynchronous Low Fare Shopping requests. See Rich Content and Branding in the Low Fare Shopping Response for details.
If a search is more oriented toward scheduling or availability than lowest fare options, an Air Availability request followed by an Air Pricing request can be made as an alternative to a Low Fare Shopping transaction.
Note: Search from multiple PCCs in a single LowFareSearchRequest is not supported.
Universal API offers two options for Low Fare Shopping:
-
A synchronous call using LowFareSearchReq. In the synchronous call, the response data from all applicable providers is returned in a single response.
-
An asynchronous call using LowFareSearchAsynchReq (v49.0 and earlier). In the asynchronous call, responses from providers and suppliers are returned as they become available.
