It used to be fairly easy to make date-changes to one leg of upgraded Lat tickets, such that the other leg didn't lose the upgrades.
Now I am encountering resistance from agents. Is the request unreasonable? Or did something change in the Amadeus backend, or was there some sort of policy change. Or, are there key phrases I need to use with agents to get this done?
(Not being able to change such tickets within the last few weeks when the upgrade window changes, (meaning a lot of R=0), makes the Lat ticket + confirmed eupgrade a less valuable combination)
