In this article we will review all of the three fare types and see, what are you able to achieve with every one of them (need to learn more about how to create a fare? Please refer to this article)
The fare types switch is situated in the central part of the fare window:
When you open it, you'll see the types themselves:
The first type is the OW - One Way - fare; it's the most simple fare type. When you set the fare to be a one way fare, it will be shown on every search of the route that you've set for this fare, and the price will always remain the same - the one that you've entered in the first prices row
The second fare type, OW/RT combination, refers to the case that you want to have a fare for one way trip, and to offer special price for return flight. This fare will show up on the route that you've set for it (even if the return date is not set) - and on the opposite route, but just in case the user searches for the the round trip (fills both departure and return dates while booking a flight). In this case you should fill the price for one way trip in the first prices row, and the price for every leg for the round-trip in the second row.
NOTE: the overall price of the round-trip booking will be the price set in the second row, multiplied by 2 (number of legs).
NOTE 2: The Combination fare does not mean, that it will work opposite route too; It will appear when searching round-trip for the current route, but if one searches for the opposite route, this fare won't show up. For this case you'll need to create the separate fare for the opposite route.
The third fare type, RT fare, refers to the case that on certain class you want to sell just the round trips. Those fairs works only in pairs; in other words, in order to make it work you should create an RT fare for the same class, for both outbound and inbound legs. In this case, only the first row of prices should be filled, and "Show only OW fares" option must be checked for that class in the class settings (Marketing -> Classes).
For example, if you want the R class on the Berlin-Madrid route to be sold just for round trip flights, you should create two fares of RT type - Berlin->Madrid and Madrid->Berlin, and in this case class R will appear in the availability search results just in case that the round trip is requested.
