Sorry, I was referring to the flight you're not trying to change. For UA-operated flights, an agent should be able to hold the inventory even though it's not available for new ticket sales. For non-UA-operated flights, I'm not sure that they'll be able to do the same thing; it may fail to re-ticket.
I don't know, 100%, that this is would be a problem. It's merely a potential problem.
