Airplane Wi-Fi is a public network shared by everyone on the flight, so it carries the same risks as Wi-Fi in a cafe or an airport. It is not more dangerous than other public Wi-Fi, but it is not private either: you cannot check who runs the network, and every passenger on board is on the same network as you.

How does airplane Wi-Fi work?
Airplane Wi-Fi works by linking a small network inside the cabin to the ground, either through satellites or through ground antennas below the flight path. Your phone joins the cabin network by name, usually after a login page where you buy a pass or accept terms. From there, your traffic travels from the plane to the provider's ground station and then onto the normal internet. That makes it a chain of networks you do not control, with many strangers connected at the same time.
What can other passengers see on plane Wi-Fi?
On plane Wi-Fi, other passengers usually cannot read pages that use HTTPS, which covers most websites and apps today. The risk is in what is left open: older apps or sites that send data without encryption, file sharing settings that let nearby devices see you, and fake login pages. A person on board could also create a hotspot with a name that looks like the airline network, which is the same trick as an evil twin in a cafe. The safest plan is to treat cabin Wi-Fi as untrusted, like any public network.
What are the main risks of in-flight Wi-Fi?
The main risks of in-flight Wi-Fi are simple and avoidable:

Does a VPN work on airplane Wi-Fi?
Yes, a VPN usually works on airplane Wi-Fi once you have bought or unlocked the pass. Turn the VPN on after the login page has let you online, because the login page itself must load first. Some in-flight networks are slow, so a connection may take a few extra seconds. With the VPN on, the cabin network and the satellite provider can see that you are connected to a VPN server, but not which sites you visit.
Frequently asked questions
Is airplane Wi-Fi safer than airport Wi-Fi?
Not really. Both are public networks shared with strangers. Airplane Wi-Fi has fewer people on it, but you still cannot check who runs each network you see, so use the same habits on both.
Can the airline see what I do online?
The network provider can see which servers your device connects to, like any internet provider. Most content is protected by HTTPS, and a VPN hides which sites you visit from the network.
Should I turn off Wi-Fi after I land?
It is a good habit. Switch off Auto-Join for the airline network in Settings > Wi-Fi so your phone does not rejoin a network with the same name later.
