Given 50% of the purchase appears to go towards your status, I would be inclined to buy enough miles to maintain E50 if it would then allow me to then gift status with someone.
Share Altitude status with friends and family
Since Altitude status is secure through 2021, if a member has already achieved status for next year, or does so by the end of 2020, they can gift it to a friend or family member.
