Biggest Wi-Fi mistakes you can make on a plane

How did we live without Wi-Fi on a plane? Oh, yeah, we read magazines! Sorry to be the bearer of bad news, but Wi-Fi isn't as protected as we hope. Fear not. I've got some tips on protecting yourself and surfing safely in the skies.

Hackers use all kinds of sneaky tactics to hijack your privacy in flight. One thing in their favor: VPNs are more likely to drop in and out in the air than on the ground. (More on that below.)

"S" for security: Only visit encrypted websites - the ones that start with "HTTPS" (that "S" is important!). In general, this blocks a hacker from viewing your activity on a given site, like the password or credit card number you typed in.

Name game: Crooks can create fake Wi-Fi networks with almost identical names to the airline's. If you're not careful, you could plug into a copycat network instead of the legit one.

I know you're not going to skip the Wi-Fi altogether. That's OK, just be smart about it.

Add a layer of security: A Virtual Private Network (VPN) encrypts your internet connection. Before accessing anything sensitive, like your email, online banking or shopping accounts, turn on your VPN. Double-check its status to ensure it's actively protecting your connection. It should display as "connected" or "secured."

Verify names. If you notice multiple Wi-Fi networks with similar names, check with the airline staff and confirm which is the right one.

Secure your devices. Invest in antivirus and malware-protection software, and keep your devices physically secure. Avoid leaving your phone, tablet or laptop unattended, even for a moment. 

Bonus: Don't post pics of your boarding pass or other travel docs

You're excited, waiting for the plane. What's the harm in posting a pic of your boarding pass? A whole lot. Boarding passes display your full legal name, ticket number and passenger name record. That six-digit code plus your last name gives anyone access to your booking information online.

The same goes for your license, passport, visa or other identification documents. Thieves keep an eye out for any detail they can use.
