A Brief History of KLM's Delft House Collectibles
"KLM’s most frequent flyers—those who fly 700 flights within a decade and reach one million Flying Blue miles—receive a rare Royal Palace Het Loo house, which is not available to other collectors (only about 100 people have this one). These most frequent flyers and important corporate customers also score an invitation to the famous reveal party each October to discover the new house."
