If you want to enjoy more comfort, you can easily upgrade your KLM flight to Premium Comfort or Business Class. You can do this before check-in opens (with Miles) and later (with Miles or cash) when you check in online or at the airport—or even after you’ve checked in. On some flights, you can receive a last-minute upgrade offer during or after check-in.

Below is an overview of KLM upgrade policy.

  • Before check-in opens, you can only book a KLM upgrade in Miles through Flying Blue’s customer service by phone.
  • After check-in opens, you can purchase an upgrade (with cash or Miles) online (My Trip 🡪 Change Flight), by phone, at the airport counter (or kiosk—paid only), boarding gate, and even on board your flight. 
  • Last-minute upgrades at the airport can be paid in Miles, by cash, or a combination of cash and Miles (i.e., up to 25% of the ticket price with Miles).
  • Reward tickets are only eligible for upgrades after check-in opens.
  • When you upgrade to a higher class:
    • The price already paid by you will be deducted from the upgraded fare.
    • You will be entitled to the benefits offered in the higher class. 
    • The XPs and Miles will only accrue to the original travel class booked by you and not to the upgraded/higher class. 
  • You can upgrade with Flying Blue Miles and XPs on KLM, Air France, and partner flights (only Platinum level members travelling on Business Class can upgrade to First Class (La Première) on Air France).
  • If you upgrade with cash, the additional Miles you earn will be on the Euros spent by you on the upgrade.
  • KLM upgrades are subject to availability.

How many KLM Miles to upgrade to Business Class?

The number of Miles to upgrade to Business Class will depend on your route. Business Class upgrades can cost anywhere between 20,000 – 30,000 Miles on short-haul flights and between 40,000 – 200,000 Miles on long-haul flights. 

To see the price in Miles, visit this page, enter the origin and destination airports, and click on the Estimate button. The starting prices in Miles will appear. To calculate the upgrade price in Miles, deduct your current fare (in Miles) from the higher-class fare (Business Class) in Miles.

For example, travelling from Amsterdam Schiphol (AMS) to New York (JFK) on Premium Economy Class will cost you about 30,000 Miles, and Business Class will cost you about 56,500 Miles. So an upgrade to Business Class will typically cost you about 26,500 Miles.
