Also, KLM only operates AMS-KBP, not AMS-IEV.
So please correct your post, because I think somewhere something went wrong?
Nothing went wrong, it is a little more complex than you may think.
Many cities have general city codes, as well as individual airport codes.
AMS - all airports: SPL and AMS, also ZYA - Amsterdam Central Railway Station
IEV - Kiev all airports, and all GDS accept this entry for KBP - Borispol and IEV - Zulhiany
MIL - Milano all airports, MXP and LIN
CAS - Casablanca all airports, CMN - Mohammmed V International
So cool down, the world is not on fire.
