I bought a pair of full fare Aeromexico J tickets to EZE for my parents a while back. There was a schedule change on AM and they rebooked them on Delta, looks like full fare J and F class. The Delta flights are not AM marketed. Looks to be like any regular delta flights.

The stock ticket is 139 (AM).

If I credit these flights to DL, what are the RDM and MQM?

Since these are not Delta stock ticket, it wouldn't be 200% MQM and 5x$ RDM. How do they deal with IRROPs MQM and RDM credit after the big change?

TIA.
