This project introduces an innovative air travel solution combining a redesigned cabin baggage with the Buddy mobile application. The cabin baggage addresses common travel issues like mobility, storage, and durability, while the Buddy app provides smart weight tracking features. Together, they form an integrated system that helps prevent common travel problems such as excess baggage fees, lost luggage, and weight management difficulties. The design prioritizes user convenience and peace of mind through thoughtful engineering and digital integration, ultimately creating a more streamlined travel experience.
