Royal Dutch Airlines (KLM)

Allowed dimensions: 55x35x25 cm · Maximum weight: 12 kg (Economy/Premium Comfort), 18 kg (Business Class)

The context in a few words

Royal Dutch Airlines (KLM) flies from Pays-Bas on a full-service model inherited from traditional aviation. In practice, that translates to a more permissive baggage policy than budget airlines — though it's still worth checking the exact figures before check-in.

55x35x25 cm and 12 kg (Economy/Premium Comfort), 18 kg (Business Class): the policy is on the lenient side. Travellers used to low-cost gauges will breathe easier here.

On the ground, posted rules and counter practice don't always align. Royal Dutch Airlines (KLM) publishes 55x35x25 cm and 12 kg (Economy/Premium Comfort), 18 kg (Business Class) as the upper bound, and gate agents typically allow 1–2 cm of leeway before routing to hold. Don't bank on it — tolerance evaporates the moment the flight fills up.

In daily use, dimensional checks are less frequent than on low-cost airlines, but the rules apply once a flight fills up. On busy short-haul routes, an oversized cabin bag may end up in the hold for free — a service that quickly becomes mandatory.

Frequent-flyer trick on Royal Dutch Airlines (KLM): use the personal item as a "stealth second carry-on". A compact backpack packed sensibly can carry a meaningful share, provided it respects underseat dimensions. That's often where a zero-fee trip turns into a forced upgrade.
