An air hostess has shared a ‘life changer’ cleaning hack to help stay safe when checking into a hotel room.

In something reminiscent of Liam Neeson’s action flick Taken, a member of KLM staff said she has developed her own personal method of keeping safe in hotels as she travels all over the world.

The hostess said in a short clip shared on Tiktok that the best way to check that nobody is under the bed without looking is to throw a bottle of water underneath it.

She said: “Throw a bottle under the bed. If it doesn’t come out on the other side” then someone could be hiding there, and you should go find a member of staff to come and investigate with you.

Demi Bonita, from Spain, also gave people a sneaky hack to check if someone’s been in your hotel room while you’ve been out, which she shared with her 70,000 TikTok followers.

She said : “Put the ‘do not disturb card’ between the door, so you can notice if someone has been in your room,” she advised.

Wearing her flight attendant uniform, she then exhibits the technique of sliding the pass between the door and wall before closing it.

“One hour later, no one has been here,” she added after leaving and then returning to the room.

Travellers have also been urged to check three other key places – behind doors, curtains and large cabinets.

Another tip is about the phone.

It may seem crazy in the days of modern mobile phones, but data roaming can be patchy or you might be charged a lot of money for making a call overseas. You don’t want to find yourself in an emergency situation in your room and discover the landline phone on the bedside table doesn’t work.

You should always check it’s functional when you arrive, get the number from front desk and test it.
