What are the options for upgrading my seat on a KLM flight?

There are several options available for upgrading your seat on a KLM flight. Firstly, you can choose to upgrade your seat using Miles, if you are a member of our Flying Blue program. The number of Miles required for an upgrade varies depending on the destination and fare class. Another option is to bid for an upgrade through our Upgrade Auctions, where you can place a bid and compete with other passengers for a chance to upgrade your seat. Additionally, you may also explore the possibility of purchasing an upgrade directly at the airport during check-in or at a self-service machine, if available. It's important to note that upgrades are subject to availability, and the availability of each option may vary based on class of service and flight.
