{{Short description|Identifier for airline fare types}}

A '''fare basis code''' (often just referred to as a '''fare basis''') is an alphabetic or alpha-numeric code used by airlines to identify a fare type and allow airline staff and travel agents to find the rules applicable to that fare. Although airlines now set their own fare basis codes, there are some patterns that have evolved over the years and may still be in use.

Airlines can create any number of booking or fare classes, to which different prices and booking conditions may apply. Fare classes are complicated and vary from airline to airline. The meaning of these codes is not often known by the passenger, but conveys information to airline staff; for example, they may indicate that a ticket was fully paid, discounted, part of an excursion package, or purchased through a loyalty scheme.

Line 10:

Booking codes were defined by [[International Air Transport Association|IATA]],{{cn|date=February 2018}} but airlines have deviated from the IATA standard and current booking codes are airline-specific.<ref name="gal12">{{cite book | title=Galileo 360(degrees).

Many airlines use nearly all letters of the alphabet to allow finer yield management. Nevertheless, certain booking codes have retained the same meaning across most airlines:

== Multiple fare basis ==

It is common for a multi-sector air ticket to have more than one fare basis, particularly if it is for carriage on more than one airline, or different classes of travel are involved. The issuing airline may often have an interline agreement to allow other airlines on the ticket. One disadvantage of this system is that if any change is made, the most restrictive fare rule, and/or the highest change fee, may apply to the entire ticket, not just the portion being changed.<ref>{{cite web |url=http://businesstravel.about.com/od/faqs/g/Glossary-Fare-Basis.htm |title=What is a Fare Basis (or fare code)? |publisher=Businesstravel.about.com |date=2014-03-03 |access-date=2014-04-24 |archive-date=2014-04-12 |archive-url=https://web.archive.org/web/20140412165100/http://businesstravel.about.com/od/faqs/g/Glossary-Fare-Basis.htm |url-status=dead }}</ref>
