This design aims to remove the carrying difficulty and also it intends to leave the narrow corridor easily.Because of the cylindrical structure , you can put the bags side to side.It can be smoothly controlled and it does not stumble on anywhere because it have big wheels.It is pulled by its narrow side, so it provides a comfortable control.Under favour of its bellow handle ,It becomes a hand luggage.It’s aesthetics desing resembles the swan.According to me, cabin crew look like a swan in their uniforms.This point provided a source of my inspiration.
P.S: you do not need to think where your luggage is because of bluetooth transmitter in it.
