Looking for a cute collectable on your next business class flight? Then maybe you need to check out these neat KLM Delft Blue Houses.

What are KLM Delft Blue houses?

If you’ve been to the Netherlands, you’d know that Amsterdam, Rotterdam, and other cities have houses with an iconic design. There are houses dating back to the 1600s, all the way up to new construction. You’ll also find canal houses that are narrow and tall, with large windows and a hook at the top. Those hooks were primarily to help haul grains or other goods to the upper floors. Some still use the hooks to move furniture, but it involves removing the window temporarily.

KLM Royal Dutch Airlines wanted a way to encourage customers to fly them repeatedly. Thus, they created a large collection of beautiful houses representing the Netherlands. Customers would get one house per flight, and to collect them all, you’ll need to keep flying KLM.

However, there needed to be a little workaround to make this happen. In the 1950s, when the first house was introduced, rules prohibited airlines from handing out gifts to customers. To get around these rules, KLM Delft Blue houses actually have alcohol in them (Jenever, or Dutch gin). By adding alcohol, KLM made the argument that the house is just a beverage container.

To drink the contents, you’ll need to remove the wax covering. There’s enough alcohol for a shot. Up to you on if you want to drink it, but we personally like the look with the seal unbroken. However, despite the seal being there, the alcohol might still eventually evaporate over time.

It’s a most definitely unique collectable in the airline industry.

How many are in the collection? Any notable houses?

By 1993, there were 60 houses available in the collection. In 1994, KLM celebrated its 75th anniversary and introduced 15 more houses to celebrate the milestone. Since then, they’ve released one house every year (on October 7) in celebration of its birthday. There are currently 106 houses available as of October 2025. These houses are reproduced, so you can still find house #1 produced in 2025 (you can check the bottom for when it was made).

Most houses are modeled after real houses that you can visit in the city. Only some of the earliest houses don’t have an address listed. To learn more about each specific house in the collection, you can check either Wikipedia or even the KLM Houses app (available on Apple or Google Play). The benefit of the app is to easily track which houses you already have.

While all houses are uniquely designed, some are also modeled after famous buildings. These include (but not limited to):

• #47 — Anne Frank House
• #48 — Rembrandt House Museum
• #75 — Former KLM headquarters
• #95 — Heineken Brewery
• #100 — Huis ten Bosch (an official residence of the Dutch monarch)

Just check the back of the house to see what number each house is.

How can you get KLM Delft Blue houses?

If you want to add a KLM Delft Blue house to your collection, take a flight in KLM World Business Class. This requires flying in their business class cabin on the following routes:

• Between Amsterdam and a non-European destination (such as Africa, Asia, or North America)
• On one of KLM’s fifth-freedom routes

At the end of your flight, the flight attendant will come through the cabin with a large collection of houses. If you are looking for a specific house, the flight attendant will gladly assist with finding what you want, but they don’t load every house on the plane. Sitting towards the front of the cabin might help give you more options.

And, yes, despite having alcohol inside them, even children in business class can take one home.

Want to know what the shortest options are for flights? Consider destinations like Lagos or Accra for flights from Amsterdam. Or, there are fifth-freedom options like between:

• Singapore and Bali
• Taipei and Manila
• Kuala Lumpur and Jakarta
• Buenos Aires and Santiago de Chile

Alternatively, you could just buy them online. You might also find them cheaper on eBay, but mind the potential shipping expense.

Special edition KLM Delft Blue houses

In addition to the normal collection, there are some special edition houses that you might stumble across. These houses can command much higher after-market prices. What makes them special edition? KLM only hands them out for limited reasons. One of the more common ways to get one of these is to earn KLM’s Platinum for Life status, where you have to earn Flying Blue Platinum status 10 years in a row. However, you additionally need to live in the Netherlands to get the house.

We’ve also heard that some people might get it if they’re on their honeymoon and informing KLM in advance. No word on how much verification KLM does to confirm.
