Like the luxury and comfort of the KLM business class? Treat yourself to upgrade! Enjoy the right to use the lounge, luxurious and spacious seats, personalized service, and exceptional dining experience. Whether flying on an intercontinental flight or within Europe, there are many ways to upgrade business class with KLM. But before knowing the techniques, you must have a clear idea about upgrades.

What is an upgrade?

When you change your economy class ticket to a business one, it is then called an upgrade.

If there are seats available, you can purchase an upgraded ticket before check-in or buy it offline during registration. In some cases, you might be provided an online last-minute paid upgrade at check-in. Updates can be provided for each flight segment-not for the entire journey. Sometimes, the price of this option can be reduced. If you purchase this upgrade at a discounted price, the accumulated Miles and XP that you earned will be the same as stated in the confirmation email of the original booking. Then comes the central question: “When can I upgrade my flight with KLM?”

The answer is simple, From the minute you schedule your ticket to the instant you check-in, you can enhance to business class by requesting the KLM Customer Service Center or make adjustments through “My Trip.” Your check-in process starts 30 hours from the departure time (24 hours before flying from the US to the US).


At the beginning of the check-in, you can only enhance if you get the last-moment paid enhancement offer or our offline order (if available). Now you can know the ways to upgrade:

Before check-in, you can upgrade online through “My Journey.” At check-in, you can purchase upgrades at the KLM Reservations website or through the KLM app. The update can be done offline at the airport through agents or kiosks, or through the KLM Customer Service Center, onboard, or in the lounge (if available) over the phone.
