CabinLink

TL;DR

It’s a browser-based map that scrapes your flight's location data from the onboard Wi-Fi so you can see where you are without waiting for the laggy seatback screen.

Who is this actually for?

Frequent flyers and aviation nerds who are tired of bloated airline apps and want raw flight data on their own devices.

The Good

• Runs directly in the browser, saving you from downloading another useless 200MB airline app.
• Gives you the actual telemetry data like altitude and ground speed without the marketing fluff.

The Catch (Potential Downsides)

It depends entirely on the airline's local Wi-Fi portal being open enough to query, which is a coin toss depending on the carrier. It might also chew through your battery if the background data fetching isn't optimized.
