If it was two one ways, there shouldn't be a no show issue.
Exactly my point / question. He should've cancelled that segment he knew he was missing (since he didn't fly THERE), his post doesn't imply that he did..
If the return ticket passed already, why didn't you cancel before return flight time (so that you wouldn't be a no show)? If it didn't yet pass, call to cancel it and ask for a fee waiver..
Not saying it can't be done now, just that it's easier to get them to do something like this proactively..
