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.

- 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.
