Is upgrading to business class cheaper at the KLM airport Counter?

Whether or not upgrading the KLM economy to business class is cheaper at the airport depends on various factors. Like other airlines, KLM Airlines releases the seats at a discounted price near the departure so that seats are total. If you are flexible and can take risks, upgrading at the airport may save you hard-earned money. However, it is not guaranteed; you should think about it in case upgrading is a must for you.
