How can I modify an existing booking with KLM?

First identify who issued and controls the ticket, then retrieve the exact KLM itinerary through the official manage-booking path. Compare the original and requested airports, dates and segments; check whether the change is voluntary or airline-initiated, whether travel has started, the fare rules, the operating airline and the live price difference before confirming anything. For KLM specifically: KLM describes My Trip self-service for trips booked through KLM, Air France or Delta, while reward tickets and other seller contexts may require another servicing path. A traveler already checked in may need to cancel check-in before changing the flight.
