Inflight WiFi is a lottery: same airline, same route, and one aircraft has Starlink while the next has a satellite dish from 2012. ConnectScore turns each airline's fleet rollout into one number from 0 to 100 — your odds of getting the good system, and whether it's free once you're on it. For United and Alaska we go a level deeper: per-flight odds, right on the booking page.
Best odds of good WiFi first. The score credits only the modern high-speed system (Starlink, Amazon Leo) at full weight — legacy satellite service counts for less, and signed-but-not-yet-flying deals count zero until the hardware is in the air.
A fleet-level score tells you which airline to prefer. These two go one level deeper — the actual flight you are about to book.
The full toolkit, updated daily:
Installing fast and free for everyone onboard — the regional jet fleet is already finished.
The share of the fleet actually carrying the system today — equipped aircraft divided by total aircraft, from the trackers where they exist and from airline announcements otherwise.
Starlink and Amazon Leo (low-earth orbit) count 1.0. Viasat, Intelsat and Gogo 2Ku count 0.6. Older geostationary systems count 0.3.
Free for everyone, or free with a free-to-join loyalty program, counts 1.0. A paid status tier, a partial rollout, or an unconfirmed free claim counts 0.85. Paid WiFi counts 0.7.
