KLM Delta Cancellation Policy – What You Need to Know

If your flight is a codeshare between KLM and Delta Airlines, the KLM Delta cancellation policy is based on the issuing airline:

When your ticket number begins with 006, Delta issued your ticket, and Delta policies are applicable.

When it begins with 074, the ticket was issued by KLM, and thus the KLM cancellation policy is applicable.

If Air France issued your ticket, then their policy is applicable accordingly.

This is most important for determining your KLM Delta Air France cancellation charge, which will differ greatly depending on fare class and destination.
