Situation: search of fares DEL-MOW. The case in point is DEL-MOW/YY/YIF.
Problem: fare rules (TVN) and routing rules are incorrectly shown for the cheaper fare.
Possible reasons for an error:
a) there are two different YY/YIF fares with different global indicators (FE and EH), different prices and difference mileage allowance (MPM)
b) KVS is not able to specify the GI in the request and obtains something with default settings
Unexplained: the eligibility rules (TVN method) mention some strange restrictions which do not seem to relate to both fares at all (Greek seaman/ government orders).
Possible solution: possibility to specify GI (with "default" settings by default to avoid questions from newcomers, EH, AT etc) would possibly solve the problem.
The GI can only be specified in the MPM queries, so you can obtain MPM for each routing type:
[KVS Availability Tool 5.1.4/Diamond - Reference: Maximum Permitted Mileage [MPM]: DEL-MOW]
Code:
GI M 5M 10M 15M 20M 25M
MPM FE 3231 3392 3554 3715 3877 4038
MPM EH 5452 5724 5997 6269 6542 6815
The permitted GI forms a part of the fare rules -- it is something that is
retrieved (based on the Fare Basis), and not something that is
requested.
Airlines should not be filing different fares with the same Fare Basis (which is the case here). When they do (and this very rare), it causes confusion and system issues, which you are experiencing...
