I am half way through a D OWE ticket. I need to change some dates, not route, but AA say that they can't, even though the next flights are on AA. After pressing they said they could reissue the whole ticket as it's not on their stock, for a fee. Is this true?

I always thought that date and time changes were straight forward and could be done with the next carrier.

(Note, it was the AA call centre in Cape Town, if that makes any difference).

Thanks.
