so that they can have more baggage storage area and oh yes, the bernouli's principle wont work properly if they would have been flat

Some are relatively flat at the bottom - especially sea planes. It's just a matter of efficiency plus round hulls take stresses better when they are pressurized.

A flat surface will provide less surface area for lift, a rounded bottom surface provides more surface area - increasing the lift, and reducing the drag.

simple aerodynamics, rounding it off creates less drag and more thrust to the body of the plane.

its actually spindle shaped . juz notice the birds. they to have that kind of a body & thats where from the idea came.
it considerably reduces the resistence.
