Please click here if you would like to upgrade your KLM ticket to Economy Comfort.
If you want to upgrade your KLM ticket to (World) Business Class, please follow these steps:
From the moment you book your ticket until check-in you can upgrade to Business Class using blue credits.
Please note that it's only possible to buy an upgrade if your ticket allows for a change/upgrade. The complete amount (fare difference + applicable penalty fees) should be paid with blue credits. It is not possible to pay for the upgrade with any other form of payment.
Payment with blue credits is subject to published rates. Please keep in mind that you can only buy an upgrade with blue credits online if your ticket wasn’t reissued before and if all flights in the reservation are operated by KLM. Please refer to the ticket confirmation to check the operating carrier.
