Yes, I expect to reissue 2 or 3 times and I agree that I'm not sure that I get full credit for surcharges on the dropped segments. I wonder whether anyone has ever received money back on a changed ticket- regardless of how much is eliminated. The offsetting concern is that fuel charges, etc. may increase after your original issue on segments that you are quite sure that you want. I'm also concerned about more restrictive conditions or interpretations being imposed. So if there is some questionable aspect and if I can get a "favorable" decision about it, I want to build it in at the start. If the interpretation of the issuing agent goes against me, I agree, I forget about it then and try it with someone else later.
