KLM has 22 Boeing 747-400 jumbo jets, 16 of which are B747-400 Combi (although depending where you look for this information, the exact number does differ).

The combi versions of the 747 have space dedicated to carrying cargo as well as passengers and so seat a maximum of 275 people, although for some configurations, it is even less than that.

Boeing 747-400 Combis have a maximum passenger capacity of 280 people (148 less than B747-400s) with 42 in World Business Class spread across the upper and lower deck.

The rear end of the plane is dedicated to carrying up to 35 tonnes of cargo.

These aircraft serve routes between Europe and Africa, Mexico, Asia, North America, the Caribbean and South America.
