The Olaf is a hybrid between a scooter and suitcase, allowing one to have both transport around the airport, as well as a space to store clothes for the trip.
The scooter section drops down from the back of the bag so that people can hop on and push themselves through the airport. Moreover once it's secured it has been tested and can be taken as a piece of carry-on, with no worrying about whether or not the size is too big. The scooter can also be used for other purposes such as scooting to school or even around the hallways (if permitted by the teachers).
This is an ideal hybrid that meets both storage and transportation needs. Photo Credits: designboom, olaf-scooter
