Complimentary status is granted for 3 months and DL Silver's would need 6250 MQM's, DL Gold's would need 12500 MQM's and DL Platinum's would need 18750 MQM's and your status would be extended until 31 January 2022. Unless things change, until 31 December 2021, you would need to achieve the regular reduced thresholds to maintain your status until 31 January 2023. Members based outside of the USA are exempt from the spending ( MQD ) requirement.

I also checked United but they are currently offering status matches only from AAdvantage and DL Skymiles members.
