Hi:

I have a DONE4 ex-IST set to begin in April. I set it up and paid for it months ago. I now want to change a destination, replacing a ORD-SLC-ORD segment with a ORD-LAX-ORD segment.

I realize that such a change requires recalculation of taxes and, I believe, a $125 fee. I called the BA North America RTW desk to make the change. They said that if they made the change they would have to reprice the entire ticket at the ex-US fare rate (several thousand $$ more!).

Is this really true? Can changes (other than date changes) to an ex-IST ticket only be made through the IST office?

Thanks for any help or suggestions.
