Hi all. I am holding a standard reward reservation LAX-HOU-LGW. I need to change the second segment to HOU-AMS, for which there is space available. CO tells me, though, that my original reservation involves "married segments," that they cannot change only the second segment, and that there is no LAX-HOU space available anymore! Are they right? Is there a workaround I can tell the CO agent so that he or she can make this change?

Thanks!
