Southwest Airlines agreed to a multi-year agreement to provide fares and inventory to users of Amadeus-owned corporate booking tools.

The agreement extends to Amadeus' e-Travel Management and iFAO's Cytric corporate booking systems, according to Amadeus. A Southwest spokesperson said "users will have access to all of the fares that Southwest makes available to our corporate customers." The deal extends live availability, last-seat inventory, fare search, integrated displays and "additional functionality related to deferred ticketing, retrieving and canceling reservations, and exchange funds toward new itineraries," according to the announcement. Southwest separately agreed last year to use Amadeus as the provider of its core reservations system. Southwest also integrates with the Concur, Deem, GetThere, nuTravel, Egencia and Orbitz for Business booking tools.
