Steve Varsano explains that a typical private jet holds about 6.4 cubic meters of luggage, roughly one suitcase per passenger. He describes a Global jet that carried 12 passengers and 48 suitcases, forcing the crew to stack bags throughout the rear cabin and galley.

One of the things people don't ever ask, which they absolutely should ask, is how much baggage can I put in my airplane? You can see that this number is 6.4 cubic meters of luggage, and this is half. And I can tell you, this is a nightmare question. Every time somebody has an airplane, they never ask this question, and this is the most important thing of every flight. I guess just to understand, what does this equate to in terms of, let's say, suitcases? This amount is about 18 suitcases. This is about 9, 8 suitcases. So it's 1 per person. But how many of your friends travel with 1 case? I was just on a plane, a Global, the newest, the longest one. There was 12 passengers, had 48 suitcases. So the last section of the airplane was just a luggage compartment. It was just piled up inside the plane. This shows you basically the difference of the usable cabin. So this is really from the kitchen door, the galley door, to the bathroom door. This is actually the size.
