The official IATA rules, when changing or cancelling flights, are:

Apply penalties

  • Per pricing unit

  • Per transaction

  • The most restrictive

Two or more pricing units within one ticket, are not related and don't affect each other.

Fare components within 1 pricing unit are related. In case of  2  different fare components, they affect each other, meaning that the most restrictive conditions apply in case of a change or a cancellation.

Or the airline overrules these official IATA rules to be checked in the penalties
