But it is easier to blame the ones who packed, it is somebody else's problem.
The airlines don't unload luggage onto the belt. The airports do. And airport baggage handlers are not going to set aside bags that don't have a priority tag and only pass through ones that do. They are going to load the bags from the bins as fast as they can, first come first served. So it's entirely a matter of loading them properly into the bins at the departure airport.
