Over the past sixty years, when flying with KLM Airlines in business class, passengers have received a complimentary blue and white Delftware KLM house (for tickets costing over 2000 euros). These houses have become highly sought-after collectibles. Notably, this year saw the creation of number 100, expanding the range from 1 to 105.
One distinctive addition to this collection is house number 96. Typically, these houses are filled with Dutch jenever (gin) and sealed with a yellow cap. However, sometimes they remain empty due to KLM flights to Muslim countries. The prevalent designs showcase Amsterdam canal houses, with the Rembrandt House and the Anne Frank House being particularly coveted. Additionally, the collection features houses representing other cities, such as the Vermeer House in Delft.
