Each published fare basis code corresponds to a fare, which applies to travelling between two cities on a certain airline, with certain restrictions.

These restrictions can include, but not limited to:

* which particular flights can / cannot be taken on this fare

* whether the fare can be used for one-way / round-trip journeys

* changeability / refundability

* restrictions on connections and stopovers

* any minimum / maximum stay requirement (applicable for round-trip fares)

* whether [[open jaw]] is allowed or not

* combinability with other fares

* advanced purchase restrictions

Fare construction is a complicated task because each fare comes with a lot of rules regarding the usage, however the rules are designed to be validatable by computers so the system can decide to accept or reject easily. Most commonly fare construction is done by a computer automatically, but it is not guaranteed that the lowest fares can be found. Due to the above reason, thereforeor in case when the automatically-generated fare has some restrictions which the traveller does not want, manual fare construction can also be done, which means finding the suitable fares manually and applying the fares to an itinerary in order to buy a ticket.
