I wasn't suggesting that the segments be kept in the ticket; sorry if that was confusing.
I was suggesting that when you call and the agent asks what the new date of travel is you explain that you do not have one yet so that the value can be kept but that you do not have to confirm the new dates now and pay a change fee now and then again when you actually have the travel dates you want to use.
