Got it, thanks again, percysmith.

So with these changes I want to make, am I correct as the following fees will apply?
1) cancelling MNL-MAD-MNL economy ($120)
2) issuing MNL - CDG pe (48,000 AM)
3) issuing MAD - MNL pe (48,000 AM)

...unless, as you've said, there are new MNL - CDG MAD - MNL slots that will open. (Any chance I can bother you to check how likely this would be? This is for Apr 12 MNL CDG (CX902 and 261) and April 30 MAD MNL (CX 320 and 901) )

If I choose to keep my economy MAD - MNL, cancel the MNL - MAD, and issue the MNL - CDG pe, what fees will I be facing? $120 cancellation fee + additional 12000 AM? Or what would be the most practical thing to do if I really want to keep the MNLCDG and MADMNL itinerary in your opinion?
