How to Get WiFi on a Plane

How Planes Get Online

In-flight WiFi relies on either Air-to-Ground (ATG) or satellite communication. ATG systems use antennas on the belly of the plane that connect to cell towers on the ground, similar to how your phone works, but with a much broader range. Satellite systems are more common for international flights, connecting to satellites in orbit. This is why you often see a significant lag when trying to access high-bandwidth content.

Managing Your Expectations

In-flight networks are shared by hundreds of passengers simultaneously, which means bandwidth is limited. You should avoid heavy activities like downloading large software updates or streaming 4K video, as this will result in poor performance for you and others on the plane. Stick to web browsing, checking email, or using messaging apps to ensure a stable experience while you travel.
