A flight attendant has shared a 'genius' trick to sneak an extra bag on board. Speaking to Express.co.uk, flight attendant Miguel Munoz revealed that passengers can avoid luggage fees by using the duty-free shopping bag method.

This involves using a duty-free shopping bag to carry clothes and other items that don't fit in the hand luggage. As "duty-free bags don't count as carry-on baggage," gate agents won't say anything.

Travellers can bring a duty-free bag from home or buy one at the duty-free shop in the airport terminal. He said: "If you have something that doesn't fit in your suitcase or you want to bring an extra bag on board, here's the trick."

"All you have to do is carry a duty-free bag. Or ask for one at the duty-free shop and you place whatever you want in the shopping bag. There is obviously limited space, but at least you are bringing an extra bag on the plane with you."

"Now you know. If you ever find yourself in that situation, just put whatever you want in a duty-free bag. You are welcome! " Another method is to use a "fake pillow," which doesn't count as a piece of luggage, to carry extra items, but holidaymakers will have to bring their own pillowcase, reports the Express.

Hundreds of travellers have been sharing a savvy trick on social media, claiming that security officers and gate agents "don't say anything".

One TikTok user shared their experience: "I did it on two transatlantic flights and it worked," while another commented: "It certainly seems genius to me! ".

Moreover, your attire can serve as an ingenious way to tote extra belongings and sidestep luggage charges. A travel guru from Handluggageonly.co.uk advised: "Pack all the clothes you need in your backpack but if that person checking you in for your flight turns around and says anything about your bag being overweight and tries to charge you the excess baggage fare, simply pop over to the bathroom and wear as many clothes as possible."

They added: "Technically, no one can say anything about the fact that you just wore your extra clothes on you instead of having them in your luggage and more importantly they can't charge you the extra fare as your bag weight should be much more in line."

Passengers are also using pockets to stash toiletries, chargers, socks, and other small essentials.
