I currently have a handwritten red carbons DONE4 ticket that my local airport had a hard time generating.

After I fly the first segment I am thinking of what I think is a simple change:

Seg 4 HKG DEL
Seg 5 DEL HKG

To

Seg 4 HKG SIN
Seg 5 SIN HKG

All the other segments (2 to 16) else stays the same.

I know I will owe fees, taxes, etc.

Will they have to reissue all the other paper tickets red carbon segments? Is this simple from the handwritter perspective?

Do I have to do this at my local airport? I just would rather use some more 'impersonal AA place'. I don't want my local AA office to hate me...they have aleady worked hard on problems caused by BA.

Any ideas on how to simplify would be appreciated.
