Yes, there is: since transfers are free, unlimited and can be any number over 5,000 miles, you can transfer some miles to them, and transfer the combined sum back! Here’s how it works:
- Family member has (say) 4,000 orphaned miles
- You transfer 5,000 miles (the minimum) to your family member
- Family member now has over 5,000 miles, so they can transfer the combined 9,000 miles to you
That’s it! And if you have multiple people in the same situation (say, kids/spouse who flew together on the same flight), you can reduce the overhead a bit by chaining the transfers: A->B->C->A.
