UA SWU on LH
Since LH will only take paper SWUs, and can only clear UGs at the gate...if there is no UG available, what happens to the unused SWU?
Do I return it to UA and it gets converted back to an electronic SWU? If so, does the expiration date revert back to the original date or does the expiration change to 12 mos from the redeposit date?
