Official rules
Community conversations identify questions. Airline, airport and regulator sources answer policy questions.
Visible uncertainty
Conflicts, incomplete records and our interpretation remain visible. Missing data does not become permission.
Checkable dates
Source-check dates are distinct from editing dates. Updating this website does not refresh an old source.
What has actually been checked
The dataset has 30 airline records. The source-read dates below come from those records; they are not refreshed by editing a guide.
- 28 Oct 20262 airline records · Philippine Airlines, Qatar Airways
- 27 Oct 20262 airline records · Cathay Pacific, Singapore Airlines
- 25 Oct 202626 airline records · See the complete source list
Each official URL retains its own recorded check date in the source list. Archives include earlier captures. Rule-logic review is recorded as 27 Oct 2026; this page’s editorial update is 30 Oct 2026. These are different checks.
Saved evidence includes full page captures and curated excerpts. Quote matching confirms that a quote occurs in saved text; it does not independently validate every derived claim. Some current browser-capture attempts failed, so we have not relabelled older archives as fresh captures. No independent human or aviation-expert audit has been completed.
Issues that remain open
- AirAsia, Vietnam Airlines and Qantas: conflicting over-100 Wh wording.
- United Airlines and Air China: incomplete or ambiguous fields.
- Some “under 100 Wh” wording does not clearly include an exact 100 Wh label.
- Individual airline implementation of the 2027 IATA standard still needs confirmation.
- We do not verify product authenticity, 3C certificates or each manufacturer’s recall database.
How a result is produced
- Use the printed Wh or an exact conversion from the actual nominal voltage. mAh without voltage produces an estimate and a request to check the label.
- Check each operating airline, count limit, date and supported departure rule. The strictest flight determines the trip headline.
- Keep carriage, use, recharging and overhead storage separate. “Not stated” stays unknown.
- Show the source and its check date with each flight. Evidence older than 30 days cannot produce a plain “within published limits”; after 90 days its confidence is low.
- Save a trip card for reference. It is not a certificate, an approval or a live source.
Maintenance, honestly
The project contains source-monitoring scripts, but a running unattended schedule has not been verified. We do not claim daily monitoring or a guaranteed response time. Changes must be reviewed against official wording before a record is updated. Logic tests and build checks catch specific errors; they cannot guarantee that all policy data is current or correct.
We cannot promise zero errors. The useful safeguards are traceable evidence, conservative handling of gaps, explicit scope and dates, and visible corrections. View corrections and updates.

The checker calculates in your browser. This build has no analytics tags, advertising scripts or form submission endpoint. Flight inputs are not placed in the URL or sent to a server by the checker. Normal page requests still reach the hosting provider, Cloudflare; external source links open their respective sites. Saved trip cards and correction notes contain the information you enter, so keep or share those files intentionally.
