Inventory Management: Opening and Closing Fare BucketsThe management of these fare buckets happens in the airline's inventory system. The Role of Revenue Management in Fare AllocationRevenue management (RM) is the "brain" behind how fare buckets are allocated. They essentially created additional fare buckets with advance purchase and stay requirements targeting leisure travelers, while keeping higher buckets for business travelers. Then the fares (prices and fare rules) are loaded, often through the industry fare clearinghouse (ATPCO) into GDS fare databases. The IATA Airline Coding Directory and ATPCO technical manuals define many of the fare class and fare filing standards.
