One option is that the other person takes an earlier flight and just waits for you to show up.
I don't think that's what they are alleging. What they are saying is that they are flexible and could take a different flight using miles. This would leave the purchased ticket for the other person but as you cannot change the name on a purchased ticket that doesn't really help them. Also as the other person isn't as flexible, getting them a FF ticket on a different flight doesn't work for either.
About the only option other than hoping a seat opens up is to buy a ticket on a different flight that is as close as possible to the OP's flight.
