Brits heading abroad this summer are being warned about a simple airport mistake that cybersecurity experts say could leave personal information vulnerable to criminals.

While many travellers focus on remembering passports, boarding passes and luggage, experts say one overlooked habit could expose phones to hackers before a holiday has even begun.

The warning centres around public USB charging ports commonly found in airports, which can appear to offer a quick fix when phone batteries are running low.

However, cybersecurity experts say some charging stations can potentially be tampered with by criminals in a scam known as "juice jacking".

The airport charging mistake travellers are being warned about

Millions of passengers rely on their phones throughout the airport journey, using them for boarding passes, flight updates, banking apps, hotel bookings and navigation.

But plugging a device directly into an unfamiliar USB charging port could potentially create a security risk.

In a technique known as juice jacking, cybercriminals can allegedly modify charging points to install malicious software or gain access to sensitive information stored on a device.

A spokesperson for Talkmobile said: "With millions jetting off this summer, it's important that travellers stay savvy when charging their phones at airports.

"The best advice is to always use your own charger and cable if you need to power up in the airport. Better still, bring a portable power bank."

5 airport phone mistakes to avoid

1. Using Public USB Charging Ports

Free charging stations may seem convenient, but experts recommend using your own plug and cable wherever possible.

Portable power banks are considered one of the safest options for travellers.

2. Connecting to Unfamiliar Wi-Fi Networks

Fake airport Wi-Fi hotspots can be used by scammers to collect information from unsuspecting users.

Travellers should always verify they are connecting to the airport's official network and consider using a VPN for additional protection.

3. Relying on Just One Travel App

While airline apps are useful for boarding passes and flight updates, experts say downloading the airport's own app can provide quicker information on gate changes and terminal facilities.

4. Not Saving a Backup Boarding Pass

Technology can fail at the worst possible moment.

Experts recommend taking a screenshot of boarding passes or saving them to a phone wallet in case apps stop working or internet access becomes unavailable.

5. Forgetting Digital Payment Backups

Many airports and airlines are increasingly cashless.

Adding payment cards to a digital wallet can provide a useful backup if a physical card is lost, stolen or left behind.

Why your phone can be more valuable than your passport to thieves

For many travellers, smartphones now contain everything needed for a trip from passports stored digitally and boarding passes to banking details and travel bookings.

That means losing access to a phone, or having personal information compromised, can quickly turn a relaxing holiday into a stressful and expensive experience.

"Protecting your data is just as important as packing your passport," the Talkmobile spokesperson said.

As airports become busier during the summer getaway season, experts say taking a few simple precautions could help travellers avoid unnecessary problems before they've even boarded their flight.
