What?
Fares are defined from “market to market”. With this feature, markets can be defined by the player, for example including certain countries, a custom set of airports, or more advances combinations like “all airports in country XY except for airports AAA, BBB and CCC”.
Why?
Makes managing fares easier, as one doesn’t have to create all possible point-to-point fares (which would be unfeasible).
When?
