In-flight Wi-Fi used to be a luxury, but today it's available on more and more flights. If you want to answer messages, download a film or just listen to music on a long flight, it pays to know in advance — which aircraft will have internet, what it will cost you and how fast it will actually be.
📶 How internet works in the air
A plane gets its internet in one of two ways. The first is from ground-based towers (air-to-ground), which only work over land and cut out over the ocean. The second is satellite (Ka/Ku-band), which works over oceans and deserts too, though it's still slower than the ground network.
Speeds are usually 5-20 Mbit/s shared across the whole cabin — enough for messaging, email and social media, but often too slow for video calls and downloading large files.
💳 What it costs — prices by airline
- Turkish Airlines — messaging is free for everyone; full internet is free for Miles&Smiles members and about $5-15 a flight for others
- Lufthansa / Austrian — FlyNet packages from around $7 on long flights, with hourly and full-flight options
- Wizz Air / Ryanair — low-cost flights usually have no onboard Wi-Fi at all
- Emirates / Qatar Airways — messaging is often free, with a full package around $10-20
- Prices vary by distance and package — you can usually pay by card right on board
Many airlines offer a free messaging tier (WhatsApp, iMessage) — for text messages you often won't even need the paid package.
✈️ Airplane mode and your phone
During the flight your phone must be in airplane mode — this is mandatory and the cabin crew will check. Once airplane mode is on, you can switch Wi-Fi back on separately if the aircraft has internet.
Remember: mobile data (4G/5G) doesn't work in flight and roaming won't kick in — the only way online is the aircraft's Wi-Fi. So if you need internet, check in advance whether your flight actually offers it.
📱 What to do before the flight
- Download films, series and music for offline use while you still have the airport Wi-Fi
- Save navigation maps and bookings offline — they'll be available with no connection
- Charge a power bank — on a long flight the screen drains the battery fast
- Download the airline's app — the free onboard entertainment library often only opens from the app
- For internet the moment you land abroad, get an eSIM for travel: best choice in 2026 in advance
Conclusion
In-flight Wi-Fi is handy but slow and sometimes pricey — on a long flight it's better to download your entertainment ahead of time and lean on the internet less.
