I have never quite got the fare rules that come up in our travel system (AMEX). Generally i can make an assumption on the fare code i am booking into based on my search parameters. But today as an example i am stumped. When i price a OW flight in Y and FC i see the exact same fare rules but a slightly different price, both should be unrestricted. Any thoughts on how i can decode what i am looking at?

The FC fare rule:

V FARE BASIS BK FARE TRAVEL-TICKET AP MINMAX RTG
1 *MA00A0RC/XX22N M X 329.50 T31JL -/1 -/ - 511
PASSENGER TYPE-ADT AUTO PRICE-YES
FROM-SFO TO-SEA CXR-DL TVL-29AUG14 RULE-YWCQ FBRNAPV/191
FARE BASIS-MA00A0RC/XX22N SPECIAL FARE DIS-L VENDOR-ATP
FARE TYPE-SAP OW-ADVANCE PURCHASE

The coach fare rule:
V FARE BASIS BK FARE TRAVEL-TICKET AP MINMAX RTG
1 *MA00A0RC/XX22N M X 329.50 T31JL -/1 -/ - 511
