Do note: the flight must be MARKETED by AeroMexico to earn this. If you book via DL.com and the flight is booked as a DL codeshare, you would earn based on if DL operated the flight, and earn MQDs based on what you paid for the ticket. You'll want to book through AeroMexico to ensure the flight is marketed by AM so you earn based on the AM rate. The same is true with other partners.
Other partner MQD earnings are available here:

Another note: Int'l Partners often offer great MQD redemptions if you can find a cheap business class fare but due to COVID right now, entry into many countries could limit what options are available.
DO NOT BOOK ON AM's website.
You want to book in Comfort Class which books into Class I (discounted J, which credits the same 40% as Full J) and many times this is reported to DL not as I, but as an upfare from a Y class and you'll have to fight with DL for the proper credit without documentation. Book through an OTA such as Orbitz which shows the correct booking Class on your receipts. Also, save all receipts, a copy of your ticket, and PAPER boarding passes.
If you're booking a US-Mexico trip such as JFK-MEX, think about something like JFK-MEX-TIJ-MEX-JFK for more miles and more MQD at about the same cost.
