Singapore to Amsterdam is a long way. Not in an abstract sense — in a very specific, 14.5-hour, I-have-now-watched-four-films-and-it-is-still-dark-outside sense. The question of whether to upgrade from Economy for CHF 700 on a flight this length is not really a question at all. It is a simple equation: divide CHF 700 by 14.5 hours, get approximately CHF 39 per hour, and decide whether a fully flat bed and a cabin crew who will bring you things is worth CHF 39 per hour for 14.5 hours. The answer is yes. The answer is always yes on a sector this long.

I had flown the outbound sector on the same routing in Premium Economy. The crew were notably friendly — warmer, actually, than the Business Class crew on the return. This is one of life's mild ironies: the people being paid extra to be extra nice are sometimes less demonstrably enthusiastic about it than the people in the cabin one step below. Make of that what you will. I made of it an upgrade request at check-in.

The seat

The new KLM cabin.
A genuine improvement they deserve credit for.

KLM spent years operating a 2-2-2 configuration in Business Class on its 777 fleet — the layout that, as we've covered elsewhere on this blog, is essentially an admission that Business Class passengers don't mind having to climb over a stranger at 3am. In mid-2023, they fixed it. The new World Business Class product on the 777-300ER uses Jamco Venture seats in a 1-2-1 reverse herringbone layout, giving every passenger direct aisle access. It's the same seat family as on their 787 fleet, with some improvements including a sliding privacy panel.

The seat is 198cm fully flat — generous, and genuinely comfortable for most body types. At 185cm I had enough room to stretch out without touching the footwell end, which puts it a step above several other carriers where the bed feels designed for someone who stopped growing at 175cm. The privacy panel, while not the full door you'd find on Qatar's Qsuites, provides meaningful separation from the aisle — enough that you don't feel exposed during the night, which matters more than it sounds on an 14.5-hour flight.

The hard product is genuinely good. Modern, well-designed, properly flat. The Dutch, it turns out, are very good at engineering things. The catering is a separate conversation.

The IFE screen is 17 inches and 4K — one of the better screens in the sky. The content selection was solid. Storage is good: a lockable compartment at shoulder height, a laptop slot under the screen, additional space under the ottoman. Wireless charging. Multiple USB and power ports in sensible locations. This is a well-thought-out seat and KLM deserves credit for finally putting it on their widebody fleet.

The sleep question

The lie-flat bed.
Worth every cent of the upgrade.

Context: on the outbound leg from Amsterdam to Singapore, I flew in Premium Economy. Solid product — more space than economy, decent recline, no complaints for a medium-haul. But not a flat bed. And at 185cm, not a sector on which I slept particularly well.

The return in Business Class was a different experience entirely. Fully flat, 198cm, proper duvet, cabin dark and quiet — I slept well. This is exactly what Business Class on a 14.5-hour sector is supposed to do, and the KLM bed delivers it. The photo above was taken early in the flight before sleep; by the time we were over the Middle East I was out.

This is the part of the upgrade argument that's hardest to quantify but easiest to feel when you land: arriving in Amsterdam having actually slept versus arriving having spent 14.5 hours performing the elaborate pantomime of trying to sleep in a reclined seat. The difference is significant. The CHF 700 looked even better in hindsight.

The soft product

The food and service.
A word about the Dutch.

The Netherlands is a country with many genuine strengths. It has excellent engineers, extraordinarily direct communication, a cycling infrastructure that shames every other nation on Earth, and Rembrandt. What it does not have — and the Dutch would be the first to tell you this, being direct people — is a globally celebrated culinary tradition.

KLM's catering reflects this with a kind of honest straightforwardness that is almost admirable. The food is fine. It is presented properly, it arrives at the right temperature, and it does not pretend to be something it isn't. A Dutch airline is not going to serve you Indonesian-inspired satay with peanut sauce at 35,000 feet (Singapore Airlines) or Omani mezze with Amouage amenity kits (Oman Air). It is going to serve you something reasonable, in correct portions, with good Dutch cheese as a highlight, and it is going to do so efficiently.

The crew were professional and direct — both of which I mean as compliments. Dutch directness at 35,000 feet means your glass gets refilled when it's empty, your requests are handled without elaboration, and there is no performance of warmth that doesn't exist. On balance, I prefer this to the alternative where someone theatrically tells you your choice of main course is "wonderful" before writing it down and forgetting it.

That said: the service was notably less warm than the Premium Economy crew on the outbound. The irony of receiving friendlier service in the cheaper cabin on the same airline on the same route remains one of the more puzzling data points I've collected in years of flying.

The main attraction

The tiny house.
The world's most confusing collectible.

Toward the end of the flight, the crew came through the Business Class cabin with a tray. On the tray were several small Delft Blue porcelain replicas of Dutch canal houses, each about 10cm tall, each filled with a small measure of Bols Genever — Dutch gin. You pick one. You take it home. This is the KLM Delft Blue house tradition, and it has been running since 1952.

The backstory is genuinely wonderful: when KLM first introduced the houses, they were brought to court for offering an unfair incentive to passengers. KLM's defence was that they were simply serving drinks in a non-standard vessel — since aviation regulations at the time specified that airlines couldn't offer gifts above a certain value, but didn't specify that alcohol had to be served in a glass. KLM won. The houses stayed. There are now 105 different houses, one released each year on KLM's birthday — October 7th.

Each house is a replica of a real Dutch building. Some are Amsterdam canal houses. Some are museums or historic landmarks. Each miniature contains a sample of Bols Genever, the famous Dutch gin. There is apparently an app to track your collection. There is apparently a secondary market where rare houses sell for thousands of euros. There is apparently a KLM Open golf tournament winner who receives a 50cm version of the Royal Palace on Dam Square each year as a prize.

I received my miniature house, admired it for a moment, and realised I had absolutely no idea what to do with it. It is now on a shelf in my flat in Zürich, where it stares at me with the quiet energy of a very small Dutch building that knows more than it's letting on.

I don't fully understand the KLM house phenomenon. I respect that it is beloved by many people and that some collectors take it extremely seriously. It is objectively a charming tradition. It is also a very small porcelain gin bottle shaped like a house, and I am not entirely sure what role it plays in my life. The Dutch, being direct, would probably respect this assessment.

The verdict

The score.
And the sleep caveat.

KLM · World Business Class · SIN–AMS · B777-300ER
KLM
7/10
New 1-2-1 seat: genuinely good. Privacy panel: useful. IFE: excellent. Food: honest and fine. Service: direct and efficient, warmer in Premium Economy than Business (unexplained). Sleep: slept well — the flat bed works. Tiny house: received, respected, slightly baffling. CHF 700 for 14.5 hours flat on one of the world's longest routes: correct decision.
The upgrade economics
CHF 48/hr
9/10
CHF 700 divided by 14.5 hours = CHF 38.89 per hour for a lie-flat seat on one of the world's longest commercial routes. Even accounting for zero sleep, this remains a compelling arithmetic argument. Would upgrade again.
