Real-time probability determined iteratively throughout a period of time

An article of manufacture including one or more non-transitory, tangible computer readable storage mediums having instructions stored thereon that, in response to execution by one or more processors, cause the one or more processors to perform operations comprising:

• determining, by the one or more processors, that there is excess of a coach seat demand for a flight (demandcoach) based on an achievable demandcoach being greater than a total number of seats in coach (CAP);
• determining, by the one or more processors, an expected marginal seat revenue for a sale of the EMSRfirst on the flight;
• determining, by the one or more processors, an expected marginal seat revenue for a sale of the EMSRcoach on the flight;
• standardizing, by the one or more processors, the demandcoach, the EMSRfirst and the EMSRcoach into a common format in a database;
• determining, by the one or more processors, that EMSRcoach is greater than EMSRfirst;
• updating, by the one or more processors, an upgrade authorization parameter to equal a total number of upgrade seats to be sold;
• and
• adjusting, by the one or more processors, the total number of upgrade seats to mitigate the risk of a double sell so that the total number of upgrade seats is less than at least one of a predetermined number or a predetermined percent of a total number of first class seats.

A system comprising:

• one or more processors;
• and
• one or more tangible, non-transitory memories configured to communicate with the one or more processors,
• the one or more tangible, non-transitory memories having instructions stored thereon that, in response to execution by the one or more processors, cause the one or more processors to perform operations comprising:
• determining, by the one or more processors, that there is excess of a coach seat demand for a flight (demandcoach) based on an achievable demandcoach being greater than a total number of seats in coach (CAP);
• determining, by the one or more processors, an expected marginal seat revenue for a sale of the EMSRfirst on the flight;
• determining, by the one or more processors, an expected marginal seat revenue for a sale of the EMSRcoach on the flight;
• standardizing, by the one or more processors, the demandcoach, the EMSRfirst and the EMSRcoach into a common format in a database;
• determining, by the one or more processors, that EMSRcoach is greater than EMSRfirst;
• updating, by the one or more processors, an upgrade authorization parameter to equal a total number of upgrade seats to be sold;
• and
• adjusting, by the one or more processors, the total number of upgrade seats to mitigate the risk of a double sell so that the total number of upgrade seats is less than at least one of a predetermined number or a predetermined percent of a total number of first class seats.
