Nice sale with Aeromexico from Seattle 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 June 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.
SEA-EZE would earn 20748 MQMs 5533 MQDs 3.69 MQD Ratio
Delta Diamond members would obtain 60861 RDMs, Platinum 49795 RDMs, Gold 44262 RDMs, Silver 38730 RDMs, Base 27664 RDMs
