How can we book an upgrade with a KLM ticket (ticket numbers starting with 074)?

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:

  1. Login using your bluebiz number and password here.
    Kindly note that it's not possible to use the login for your KLM or Flying Blue account during the booking process. Therefore, please make sure to first log out from your KLM or Flying Blue account before you proceed with booking the upgrade.
  2. After logging in with your bluebiz account, please log in to MyTrip to access your reservation.
  3. You can now upgrade your ticket and proceed to the payment page to choose the blue credits payment option.
  4. If you have enough blue credits in your bluebiz account, the options will be added to your reservation and you will receive a booking confirmation by e-mail.

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.
