Recent rule updates
- 2026-05-26Added Canadian carriers Porter, WestJet, Air Transat and Flair (economy, soft-sided-required) with published dimensions, weight limits and official source links. Flair in-cabin is domestic-Canada only.
- 2026-05-26Re-verified all 8 original airlines against current public policy (May 2026). Corrected Air Canada and Lufthansa to soft-sided-required, and JetBlue to allow hard-sided (soft preferred). Sources cross-checked against current guides; airlines' own pages couldn't be fetched directly (bot-protected), so values reflect current published policy as cited by those sources.
- 2026-05-26Fixed United/Alaska hard-carrier notes, clarified American soft vs hard limits, and documented Southwest's 8.5/9.5 in height ambiguity (using the conservative figure).
- 2026-01-15Verified Air Canada and Lufthansa in-cabin limits against their official policy pages.
- 2026-01-12Added United and Delta; flagged Delta as having no fixed published dimensions.
- 2026-01-09Added American, Southwest, JetBlue and Alaska economy rules with source links.
- 2026-01-14Added a Lufthansa business-cabin rule (separate from economy).
