Flying with your phone this Thanksgiving? Here’s how to stay safe, connected, and sane while navigating the busiest travel day of the year.
If you’re braving the Wednesday-before-Thanksgiving airport chaos (may the odds be ever in your boarding group’s favor), your phone becomes the most important thing you own. It’s your boarding pass, your map, your credit card, your entertainment, and your “sorry, running late, blame TSA” lifeline.
But with all that extra airport Wi-Fi, questionable chargers, and mid-flight rule-following (or not), it raises a million little questions. What’s actually safe? What’s a myth? And what will get you side-eyed by a flight attendant before you even reach 30,000 feet?
Let’s break down the smartest ways to fly with your phone—so you can get to your turkey, tequila, or chosen family gathering without a digital meltdown.
Is it safe to use airport Wi-Fi?
The fear of public Wi-Fi hotspots is something of a relic, according to experts who spoke with the Washington Post. These days, most reputable websites and apps use HTTPS. This protocol encrypts data, making it very hard for potential digital eavesdroppers to spy on you. Before leaving home, make the most of HTTPS by setting your web browser to use only that connection type.
Check to ensure your web activity uses HTTPS by looking for these letters at the start of any URL or website address. Pages that start with HTTP are not encrypted. It’s more difficult to tell whether mobile apps encrypt their traffic, so surfing for entertainment is better than accessing sensitive information while out and about.
If you’re checking particularly sensitive information—say, your bank account—you can upgrade your security with a trustworthy virtual private network. VPNs further encrypt your digital traffic, making it virtually impossible for any eavesdropper to access it. Still, before connecting to an unsecured public Wi-Fi, use your mobile network to turn your phone into a hotspot.
What happens if you don’t use airplane mode?
The Federal Aviation Administration bans cell phone calls on flights because of how the phone’s signals interact with the plane’s electronics. However, you can still use your phone if you put it in the aptly titled “airplane mode.” This mode, which is standard on all modern smartphones, disables the phone’s cellular connection as well as its Bluetooth and Wi-Fi capabilities.
It’s worth keeping in mind that forgetting to turn on airplane mode is extremely unlikely to endanger your flight. As it turns out, according to a 2017 survey by Allianz Global Assistance, 2 in 5 people report leaving their cell service enabled on flights, and there’s no evidence signal interference from a cellphone has ever caused a crash. It’s still best to listen to the airline’s guidance regarding cell phone use in-flight.
Can you trust the chargers on the plane?
While not quite an out-of-date belief, “juice jacking“—a technique where a hacker uses public chargers to install spyware on your phone—is relatively unlikely, according to experts who spoke with the Washington Post. According to the FCC, cybersecurity experts warn that general public USB ports can have malware installed. If a public USB charging port prompts you to share data once you plug in your phone or mobile device, don’t.
There are safer ways to charge your phone. Use your own charging cable and turn your phone off while it charges. If you want to be extra cautious, use a data-blocking adapter. These plugs connect to your USB cord and block its ability to transfer data, allowing you to charge safely.
How can you conserve your battery on a long flight?
If your phone is your boarding pass, your ride planner to your hotel, and credit card to pay for said hotel, you need it to be on. Airplane mode will save you some precious battery time by disabling a few energy-draining features of your phone. Even more useful are the battery-saving modes, which turn off certain features like email fetching or lower the phones brightness, that most phone manufacturers offer.
If you’re still getting dinged with low-battery warnings, invest in a portable charger—a compact, spare power bank that can get you back to 100%.
What’s with all the rules about lithium batteries?
If you’ve taken a flight recently, you’ve undoubtedly heard the rules about lithium batteries. For instance, if you check a bag with a lithium-battery-powered device, that device must be powered off. You must also keep any spare lithium batteries in your carry-on luggage.
The reason for all this? It’s a lot more vital than keeping your phone in airplane mode. In the past five years, the number of fires related to lithium-ion batteries has jumped over 40%, according to a CBS News analysis of Federal Aviation Administration data.
