The hold baggage capacity of passenger planes is commonly quoted in LD3 positions. It is a huge deal that Boeing 767, because of its narrow fuselage, has few LD3 positions, even though there is much hold volume and many LD2 positions.

Which planes have most IATA cabin baggage positions?

IATA cabin baggage is 56 cm x 46 cm x 25 cm.

Embraer publishes E-jet cross-section. And E-jet overhead bins do not fit IATA baggage. The available bin size on E-jets is 60 cm x 40 cm x 25 cm, so 46 cm wide baggage cannot fit.

Conceivably baggage might fit under seat. But the size and shape of underseat volume is not shown. Note that the back of the seat above is just 45 cm or so wide in coach. The seat legs must go somewhere, and IFE boxes, and life vests... how big baggage fits underseat?

Boeing, on their site, does not publish the sizes and shapes of their bins.

Airlines do publish allowed sizes of cabin baggage. But seeing how they commonly fail to specify airplane model and quote different sizes for airlines operating same model, it is not clear what the actual airframe capacities are.

So... which planes can carry IATA baggage? And how does the number of IATA baggage positions compare with the number of seats?
