Irishman Mr Power, 57, who lives near Antwerp in Belgium, said he travels twice a week using budget airlines.

Engineer John Power invented the ‘wearable luggage’ to beat the baggage charges levied by budget airlines. A £56 coat, made of light but strong polyester, has 14 variously-sized pockets which can hold a total of 15kg of luggage. After boarding, the Jaktogo can be folded up and carried as a shoulder bag. It also comes in a dress version.
