Multiple AirfareSeveral fares
You have probably been on a trip where the passenger next to you pays more (or maybe less) than you, and that's because of these basic tariffs. As well as using vibrant price algorithm and strategy to enable carriers to optimise seat fares according to specific city, route, date, time and seat demands, carriers have also used different tariff bases and tariff code to distinguish all these similar seat types on a given aircraft.
Travellers can use these numbers to help them better comprehend what is available to them in relation to air upgrade and to see if the air they are on will be full or not. Instead of spending a lot of patience awaiting support, experienced travellers who know how to check the basic ticket price can quickly judge whether they can be moved to a better place or not.
The tariff base (or tariff codes) are usually indicated by a sign such as either letter A, J, Y or letter L. For example, characters such as "L, M, N, Q, T, V and X" usually relate to reduced rate Economy IC travel, while characters such as J and C relate to Travel Express and letter C to First IC travel.
Normally there is another character after the first character that indicates the tariff category (e.g. Q or Y). As a rule, these subsequent charges specify other features of the ticketing, such as eligibility for reimbursement or residence requirement. However, some carriers have only one or two signs (e.g. "YL"), while others have more.
If you have more than one flight, your route may contain several tariffs. Note, however, that for a route that consists of several tariff code, you may be limited by the restrictions of the most rule-based part. Therefore, if part of your trip is non-refundable and the next part is non-refundable, the whole of your travel may not be reimbursable.
