From what I understand the highest level you could reach on MH andoneworld flights is Enrich Gold/ow Sapphire.
To reach Enrich Platinum/ow Emerald you have to fly exclusively on MH. That's 100,000 MQM or 130 MQS.
They have Delta, Etihad and even Firefly as partners to earn miles but not counted for status.
It says on their website:
"Enrich Platinum
In the upper echelons of luxury travel, the privileges are unsurpassed.
Requirements
Qualification
100,000 Elite Miles or 130 Elite Sectors
(in one calendar year)
Requalification
100,000 Elite Miles or 100 Elite Sectors
(in one calendar year)"
Surely it's not just exclusive travel on MH?
