How KLM's personal item compares

At 15.7 x 11.8 x 5.9 in it holds roughly 1093 cubic inches, about 37% of the volume of KLM's own 21.7 x 13.8 x 9.8 in carry-on. That is larger than 1 of the 16 other airlines that publish a figure, and smaller than 12.

Worth knowing: 6 of the 23 airlines we track publish no personal-item measurement at all, so a bag chosen against KLM's stated 15.7 x 11.8 x 5.9 in is being measured against a firmer rule than most carriers give you.

Personal item vs carry-on on KLM

Both bags are included in the fare on KLM, so the personal item is an addition to your 21.7 x 13.8 x 9.8 in carry-on rather than a replacement for it. The two limits are judged separately — a bag that is too big for under the seat may still be fine overhead.

How KLM enforces it

KLM publishes a cabin weight limit of 26 lb (12 kg) — 12 kg COMBINED across the hand baggage and the small bag in Economy (18 kg in Business) — not a per-bag limit. Weight is checked far less often than size, but it is the rule most likely to catch you on a bag full of books or camera gear.

On full flights KLM may ask you to check hand baggage at the gate free of charge, even if it meets the size limit. An over-large personal item usually travels overhead instead, which is free on KLM and therefore a much softer landing than on a carrier that charges for the carry-on.

Two practical notes that apply on any airline: the under-seat space is smaller in a row with a lifejacket box or an entertainment unit beneath the seat, and a soft bag that compresses will pass where a rigid case of identical stated dimensions will not. Measure with anything strapped to the outside included.
