Hi,
I have booked a flight with you from Ho Chi Minh to Paris return. On the leg back I fly from Paris to Amsterdam with KLM and from Amsterdam to HCM with you. AS I will be in Amsterdam visiting friends i would like to start my journey in Amsterdam. And cancel the Paris Amsterdam leg.

Please let me know how to proceed to do this as i am worried that my whole flight will be cancelled if I do not start in Paris.

Thanks
Taona
