The verdicts, where you book
FlightWifi adds one honest chip to every flight result: video calls work, email and browsing, varies by aircraft, or no Wi-Fi. Matched to the exact aircraft, sourced from official pages, computed entirely in your browser.

What it checks that airlines won't tell you
Exact aircraft, not fleet averages
A mid-rollout airline gets a per-plane answer, because that is how retrofits actually happen.
Call policy included
Fast wifi where the airline bans calls says so: Fast, but no calls.
Trips roll up honestly
A two-leg trip where one leg has nothing says Not on every aircraft, not a cheerful average.
Sources one hover away
Every verdict's tooltip names the system, the rollout state and the official sources behind it.
Verdicts it shows
The label system is deliberate: the first words name what varies, and no chip ever promises more than the sources support. When we don't know, it says so.
