This is correct if you're not upgrading all segments on the same fare component.

For instance, suppose you have a RT from AAA to BBB, with connections in both directions, at XXX outbound and YYY on the return. Assume that you do *not* have a broken fare. Then to get the additional MQMs you would need to pay to upgrade both the AAA-XXX and XXX-BBB segments (or both BBB-YYY and YYY-AAA segments). If you upgrade only one segment on this RT itinerary (or if you upgrade only AAA-XXX and YYY-AAA or only XXX-BBB and BBB-YYY, assuming that you do not have a broken fare or multicity itinerary), DL will treat it like a seat purchase and not reissue the ticket in a FC fare class.
