Nice sale with Aeromexico from San Francisco to Buenos Aires via Mexico City. The nice thing about Aeromexico is that it credits as 40% of Distance to Delta as MQDs so it's a very efficient and effective way to pad your account. Sample dates are in March 2021, when hopefully Argentina will open their borders and Covid-19 calms down, usual Aeromexico has terrible food pre-Covid, is currently in Chapter 11 bankruptcy, etc. but this is a super earner for MQMs and MQDs.
SFO-EZE would earn 19395 MQMs 5172 MQDs 3.13 MQD Ratio
Delta Diamond members would obtain 56892 RDMs, Platinum 46548 RDMs, Gold 41376 RDMs, Silver 36204 RDMs, Base 25860 RDMs
