I am a bit confused at the terms and conditions of the offer.
Do I read it correctly that a recipient can only get up to 50,000 bonus miles via this offer?
So in theory
A --> B 50k miles. B receives 75k miles. A receives 25k miles back.
Repeat
A --> B 50k miles. B receives 75k miles. A receives 25k miles back.
End result
A has 50k less miles than they started with
B has 150k miles more than they started with
Correct?
