If you are asking what various fares earn, the table for Delta flights can be found here -- https://www.delta.com/us/en/skymiles...arn-with-delta

There are five fare classes for business/first flights J, C, D, I, and Z which is generally the order from most costly to cheapest (although there can be overlap). Only J class is considered full fare and earns 200% MQM's. The others earn 150% MQM. There's no class of service bonus for mileage earn. There are typically multiple fare filings for each fare class (although the higher fare classes are the least restrictive and may only have 1 or 2). The lower ones tend to have different restrictions such as advance purchase requirements (cheaper fares generally require they be purchased further in advance) or a roundtrip booking requirement with a Saturday night stay (this is typical of the cheaper Z fares) . The specific fares you purchased are identified by an 8-character fare basis code which can found in the Fare Details: line in the email receipts. You can see all the fares filed on a route with an account on expertflyer.com.
