Airplane Wi-Fi is about as safe as hotel or airport Wi-Fi: one network shared by everyone on board, run by a company such as Viasat, Intelsat, Panasonic Avionics or Starlink. Https:// sites stay private on it; the provider sees which sites you open, and websites often think you're in another country.

Columbus, Ohio, United States · Anthropic, PBC
Anthropic, PBC is an ordinary internet provider. Homes, offices and most hotels and cafés look like this from outside, so the name alone can't tell which one you're on. The questions below can. This doesn't look like in-flight Wi-Fi: Anthropic, PBC is a ground network. Open this page again once you're on it.

Questions Only You Can Answer
Did your device ask for a Wi-Fi password when you joined?The network's own password, not a login page in the browser.
The air between your device and the router is encrypted. Everyone with the same password is inside it too, though: on older (WPA2) networks someone with that password and the right tools can decode other people's traffic.An open network: anything that isn't https:// goes over the air as it is, and anyone nearby can record it. Phones list such networks without a padlock, often with a warning like "Unsecured network".Look at your Wi-Fi list: a padlock next to the network's name means it needs a password.
Did you get the network's exact name from staff, a sign or the airline?
Good. Fake hotspots copy names like "Free_Airport_WiFi" and wait for people to pick theirs.Ask for it. Anyone can name a hotspot after the place, and your device can't tell the real one from a copy. Two networks with almost the same name are a reason to ask.If you picked it from the list because the name fit, ask staff whether it's theirs.
Did a login page ask for the password of another account (Google, Facebook, email) or for card details for free Wi-Fi?
Normal: real login pages ask for a room number, an email address, a seat or booking number, or just a click.Don't type it. Free Wi-Fi has no reason to need your account password, and fake hotspots use such pages to collect logins. If you already did, change that password over mobile data.Fine: many networks have none.

Who runs the Wi-Fi on a plane
Airlines buy it from in-flight providers. Your traffic goes from the plane to a satellite or a ground tower and comes out at the provider's ground station, so the network websites see is the provider's, placed where that station is: often another state or country. That's why sites may show you another country's prices or catalog in the air.
Satellites high above the earth add half a second or more to every request; the round trip check above shows it. Starlink's satellites fly much lower, so it feels closer to home internet.
Fake Wi-Fi on board
In 2024 Australian police charged a man accused of setting up fake free Wi-Fi networks on domestic flights and at airports, with login pages that asked for people's email or social media details. Connect only to the network the airline names on the seat card, the screen or in the announcement.
What a web page can't check
Whether the network has a password. Your device knows (the padlock in the Wi-Fi list); a page doesn't.
Whether it's the real network or a copy with the same name.
Whether other devices on it can reach yours. Good public networks keep guests apart from each other; no page can test it.
Who else is connected, and what runs on the router.
How to stay safe on airplane Wi-Fi
Join only the network the airline names, and ignore look-alikes that show up in the list mid-flight.
Pay for Wi-Fi only on the airline's own login page, not through a link or a pop-up.
Download what you need before boarding: the whole plane shares the connection.
Free messaging-only plans let only chat apps through; a VPN usually won't connect on them.
Set AirDrop to Contacts Only, or strangers in nearby seats can send you files.
Can the airline see what I'm doing on Wi-Fi?
The airline and its provider can see which sites you open and how much data you use, and tie it to your seat or account if you logged in with one. They can't read https:// pages or what you type on them.
Why do websites think I'm in another country on plane Wi-Fi?
Your traffic reaches the internet at the provider's ground station, and sites place you there. It can be on another continent from the one you're flying over.
Can I use a VPN on airplane Wi-Fi?
On full internet plans, usually yes, a little slower. Free messaging-only plans let only chat apps through, so a VPN won't connect on them.
