Surely she can avoid violating the contract of carriage by canceling the award reservation. And if it is not worth it to her to pay to redeposit the miles then surely she can cancel the award reservation and just tell the agent she does not want to redeposit the miles. Though I like the idea here http://www.flyertalk.com/forum/delta...me-time.html#4 to at least try to redeposit the miles without paying.
