Method

One reviewed rule per airline

The index starts with 123 selected personal-item rules, one per airline, using the existing rule-selection order. It keeps 117 rules that are complete on all three axes and meet the exact, reviewed-source standard.

3 selected rules are incomplete and 3 complete rows use conservative estimated placeholders. Both groups are excluded rather than presented as official dimensions.

The selected exact rules were reviewed between 2026-05-28 and 2026-06-15. Rule-specific caveats remain on the airline guide pages.

Important boundary

Dimensional compatibility is not airport testing

  • Published bag dimensions may differ from the packed, expanded, or soft-sided shape at the gate.
  • Fare, route, aircraft, storage, staff discretion, and policy changes can alter the real-world outcome.
  • Use each bag page's source dates and reviewed evidence before buying or travelling.

Start with the calculation method and open a ranked bag's detail page for its source record.
