What is it?
In detail: the API predicts the direction of the lowest published fare and returns a ("Buy Now" "Buy Soon" or "Wait") recommendation of whether to purchase, based on:
- historical price changes—the API uses the Travel Insight engine to retrieve 13 months of historical shopped fares for a given city pair/travel date available in the Sabre® cache to compare to the lowest published fare.
- direction coupled with percent probability—the API predicts a direction that the then-current lowest published fare is predicted to go–increase, decrease, or stay within $20 of the lowest published fare in the next 7 days—and returns a percent probability that the fare will go in that direction.
For example, if a value of 95 is returned for percent Probability, with a Direction of Increase, then there is a 95% probability that the lowest published fare will go up $20 or more in the next 7 days. Therefore, there is a very strong indication that fares will go up and a Recommendation of "Buy Now" will be returned.
Why use it?
You could use this API to notify travelers that a flight price is predicted to go up/down and the percent probability that the change in direction will occur. For example, when the service returns a Buy Now recommendation, an indication of Increase, and a Probability of 95, the client app can notify the end user with a message and recommendation. The message could say "Buy now and avoid a projected price increase. Our algorithm projects a 95% probability that fares to San Francisco will rise more than $20 in the next 7 days."
How it works?
Data used for predicted and lowest published fares
The API uses the same data for the predicted probability and lowest published fares, with these minor differences:
- The predictions are based on 13 months of historical shopped fares. If 13 months of data are not available, the API uses the maximum months available. The last date for the shopped fare data ends on the Sunday before an API request is submitted. The API retrieves the shopped fares from Sabre GDS shopping responses to shopping requests made from points of sale in the U.S. and Canada.
- The lowest published fare is retrieved from shopping responses from the Sabre GDS to shopping requests for fares made from points of sale in the U.S.
The API uses this data for the predictions and the lowest published fares available via the Sabre GDS:
- Published fares are for single adult, roundtrip travel in the economy class of service.
- Total fares: All taxes and fees are included; however, ancillary fees charged by airlines, such as baggage and preferred seating, are not included.
- Flight types: nonstop, connecting, direct, and flights with stops
- All departure and arrival times of day
- Departure and return dates are a maximum of 60 days into the future
- Certain origins and destinations located in the United States, Puerto Rico, and the U.S. Virgin Islands

City Pairs Lookup API
There are multiple endpoints for the City Pairs Lookup API. One endpoint is for city pairs that apply to the Low Fare Forecast API. See the City Pairs Lookup API page for the specific HTTP method and endpoint.
InstaFlights Search API
The InstaFlights Search API retrieves roundtrip flight itineraries with published fares and fare breakdowns available from the Sabre® cache for a certain origin, destination, and roundtrip travel dates. The origins and destinations are airport codes.
