Our flight forecast verification program
We are building a public record of forecast snapshots before publishing accuracy statistics. This page includes the first dated coverage baseline and the limits that prevent an accuracy claim.

A forecast should not call itself accurate simply because it uses reputable inputs. CheckFlightComfort.com has begun saving anonymous forecast snapshots so future claims can be tested against a documented comparison method.
Saved without passenger identity
Distinct airport combinations observed
Requires a documented minimum sample and comparison method
First coverage report: September 21, 2026
This first baseline describes what the collection system stored from August 7 through September 18, 2026. It is a coverage report, not an accuracy report. The rows include repeated checks and internal or owner testing. They are not unique passengers, unique flights, or a representative sample of airline traffic.
64
Successful route forecasts stored during the period. Repeated checks are separate snapshots.
20
Distinct departure and arrival combinations. A route in the opposite direction counts separately.
31 moderate and 33 limited
Coverage and timing labels at the moment of each check, not a grade for the final ride.
56
The estimated path overlapped part of the site's United States advisory coverage. It does not mean every route segment had equal detail.
8
The site disclosed that advisory coverage could be more limited on those international paths.
24
An advisory intersected the estimated route window. It is not proof that the aircraft entered the area.
39
A recent report was found near the estimated route. Reports outside the near departure window were context only.
What the baseline reveals
The collection pipeline is working across domestic, oceanic, and international examples, and it preserves confidence and coverage limitations beside the score. It also reveals a serious sampling imbalance: LAX to JFK and LAX to Cancun account for 31 of the 64 snapshots. That concentration is useful for testing repeated changes on familiar routes, but it is not broad enough for a sitewide accuracy statistic.
The baseline also lacks a consistent independent observation of how each completed flight actually felt. A pilot report near a route is not automatically a match for the checked flight, and no pilot report is not proof of smooth air. The current dataset can measure whether the forecast system stored its inputs and limitations. It cannot yet establish how often the comfort label matched the passenger experience.
What a snapshot contains
- Departure and arrival airport codes
- Departure day and optional flight number
- Comfort score and strongest route signal
- Counts of relevant advisories and nearby positive pilot reports
- Available signal count, confidence label, and coverage summary
No passenger name, email address, payment information, or precise device location is stored in the verification snapshot.
Why an accuracy percentage is not shown yet
A small or biased sample could create a reassuring looking number that means very little. Before publishing an accuracy rate, the service needs enough routes, a defined observation window, rules for missing reports, and separate treatment of turbulence advisories, airport weather, and actual ride reports.
Planned comparison principles
- Freeze the prediction: use the forecast that existed at a defined lead time.
- Define the observation window: compare only reports reasonably near the estimated route, altitude, and flight period.
- Separate absence from evidence: no pilot report does not automatically mean smooth air.
- Publish false alarms and misses: report both directions instead of selecting flattering examples.
- Segment the results: show lead time and geographic coverage so unlike forecasts are not mixed together.
What will be published
Once the dataset and rules are sufficient, this page is intended to report sample size, route coverage, lead time groups, signal availability, false alarm frequency, missed stronger signals, and clearly stated limitations. Until then, the honest result is “collecting baseline.”
