See which flight has better odds of next-gen WiFi.
WiFi Odds adds next-gen WiFi estimates to the flights on your booking page. If one option meets the recommendation checks, WiFi Odds names it.
How the extension labels and sorts flights.
Checks public history
United and Alaska flights can get per-flight next-gen WiFi history from public trackers.
Adds a clear label
Each number says whether it describes that flight or the airline as a whole.
Sorts where undo works
Supported United and Alaska pages use automatic sorting. Keep site order puts each row back.
The two measures answer different questions. Next-Gen estimates the chance that a flight uses a Starlink or Amazon Leo aircraft. The WiFi Odds site’s Streaming score rates an airline’s WiFi across its whole fleet. The current extension labels are listed in the release notes below.

Messages shown on flight rows
Per-flight odds
The tracker has dated history for this United or Alaska flight. WiFi Odds can compare it after the sample and confidence checks pass.
Airline-wide score
The booking page does not provide supported flight history. The WiFi Odds site’s Streaming score rates the airline across its whole fleet. The current Store extension labels are listed in the release notes for version 3.0.2.
Part of the fleet has data
The published score covers a named part of the fleet. WiFi Odds shows that limit and leaves the remaining aircraft unknown.
No usable history
The tracker did not return enough history. WiFi Odds shows unknown, does not use 0%, and leaves the row out of the ranking.
Lookup in progress
WiFi Odds shows a loading message while it waits for the tracker.
Lookup unavailable
The tracker request failed. WiFi Odds keeps the booking site’s order and identifies the lookup error.
No flight number
The booking page did not provide an operating flight number. WiFi Odds can show an airline-wide score, but it cannot rank the row as a known flight.
Messages shown in the Best WiFi choice panel
Best WiFi choice
WiFi Odds recommends a flight after it finds at least two scored options, an eight-point lead, and medium or high tracker confidence.
Aircraft confirmed
The airline has published the aircraft assignment for the travel date. WiFi Odds shows that assignment next to the historical estimate.
No clear winner: close scores
The leading flights are less than eight points apart. WiFi Odds shows both estimates without recommending one.
No clear winner: limited history
One flight leads, but the tracker confidence is too low for a recommendation.
Not enough flights to compare
One supported flight has a usable score. WiFi Odds leaves the other flights unscored and keeps their order.
Comparison in progress
WiFi Odds waits for the tracker before it shows a recommendation or a no-data message.
No comparison available
The tracker returned no direct-flight history for the route. WiFi Odds keeps the flights unscored.
Install and site-access requirements.
Site access

Where the numbers come from
