Are you still worried about overcharging for your luggage over the weight limit? An " Airport Jacket" containing up to 15kg luggage is designed to help frequent flyers bypass(绕过)  airport baggage queues, reduce baggage fees and really lower the risk of lost luggage.

" With airlines beginning to charge for carry - on baggage as well as severely limiting 10aggage allowances for the low fare economy traveler, my partner and I have designed a jacket that can wear your laptop,  tablet,  two pairs of shoes,  a pair of jeans,  five T - shirts, a jumper and a camera," designer Claire Murphy explains.  "It totals 14 deep pockets, including 8 pockets at hip length, 11 pockets at three - quarter length and 14 pockets at full length. "

. Claire and Benke Murphy came up with the idea while traveling home with their newborn child. They had so much extra carry - on luggage that the airline tried to charge them $ 140 for it, more than the cost of their tickets.  So they had to put clothes, chargers, diapers and toys into their pockets, until just over the weight limit.  They escaped the tax, but everything sticking out of their pocket saw a pretty uncomfortable plane ride.

However, people have been raising questions about the usefulness of the Airport Jacket, especially the trouble of going through security checkpoints. They are arguing that having to take all out and then putting them back into the pockets is not worth the few tens of dollars you save on a checked luggage.

But Benke claims that walking through airport security is not an issue as long as you follow guidelines for carry - on luggage. " It only needs to be worn when checking in and at the boarding gate. What' s more, Airport security is not looking at how you store your luggage but checking its contents. "

Its makers are currently running a crowdfunding campaign on Kickstarter, trying to raise  $ AU100, 000. But they've only raised $ AU3, 675 so far, although they still have 37 days to go, so it's still hopeful And even if this fails, they may still find a way to get it to market.
