Monthly rule digest
Launch-month rule-change digest
CarrySizer moved from launch data into a monthly digest format: reviewed policies, watched high-risk carriers, and changed tool logic are now grouped in one public log.
170 airline records are tracked; 162 operating airlines are available in current tools, with historical records separated.
Fare/add-on caveats are now surfaced in route checks for basic fares, paid cabin bags, and priority-style upgrades.
No rule is auto-published from unofficial sources; suspected changes stay internal until manually reviewed.
Top watched airline records
Priority cabin-bag and free personal-item assumptions verified for checker and route flows.
Strict EU LCC enforcement makes this one of the highest-impact policy pages.
Wizz Priority vs free small-bag model verified across checker, route, and fee contexts.
Frequent confusion between 40x30x20 cm free bags and 55x40x23 cm priority cabin bags.
Large cabin bag vs underseat allowance remains a watched distinction for UK/EU traffic.
Readers often compare easyJet's 45x36x20 cm underseat bag with paid cabin-bag options.
Recently added UK leisure carrier with a fresh source date and compact summary.
High seasonal demand and holiday routes make Jet2 a useful digest watch item.
Recently added long-haul UK carrier with 56x36x23 cm / 10 kg economy modelling.
Long-haul travellers tend to care about both dimensions and weight before airport arrival.
Official baggage-policy corrections for ten carriers
- Corrected Cebu Pacific 5J to a 10 kg combined cabin allowance with a separate under-seat item from 15 September; Cebgo DG remains at 7 kg.
- Corrected Eurowings Basic's small bag to 40×30×25 cm and the large cabin bag to 8 kg; removed unsupported free hold and fixed-fee claims.
- Corrected Allegiant's free personal-item and paid carry-on dimensions, removed unsupported cabin weight limits and fixed baggage-price estimates.
- Corrected AirAsia's two-piece 7 kg combined allowance and removed unsupported fixed add-on prices and the obsolete 14 kg guide claim.
- Corrected Bangkok Airways' 7 kg single-item limit and the ATR72-versus-Airbus size difference; the previously quoted 20 kg is checked baggage.
- Corrected JetBlue: all current fares include one carry-on and one personal item; Blue Basic gained the carry-on in 2024, and the personal-item depth is 8 inches.
- Clarified Royal Brunei's one-bag Economy allowance and its two-piece Business allowance with a 12 kg combined cap.
- Corrected Norwegian's LowFare under-seat bag and the 10 kg/15 kg combined cabin limits by fare.
- Corrected Vueling's 55×40×20 cm overhead size and current Fly Light, Fly, and Fly Grande baggage inclusion.
- Corrected Wizz Air UK's free under-seat bag to 10 kg, the wheel-size rule, and removed unverified fixed-price estimates.
- Reconciled 25 indexable direct translations of the affected guides and three additional indexable guides with the same official policies. Other airline records and held translations remain in the planned review queue.
- Each corrected airline record links to the official policy sections checked in this AI-assisted source review; no independent human verification is claimed.
Source-backed baggage corrections and clearer evidence
- Corrected Ryanair’s free bag to 40×30×20 cm and separated Priority entitlement from physical fit, including guides, translations and tool actions.
- Rechecked Qatar and Air New Zealand checked-bag allowances, United Basic Economy exceptions, EgyptAir cabin limits and easyJet’s 15 kg cabin-bag limit.
- Updated knife and battery guidance with jurisdiction and rule-version limits; reviewed nine existing product shortlists against named manufacturer models and sources.
- Moved seven incorrectly active airline records into their sourced ceased/suspended status. Historical pages remain available and are excluded from trip-planning tools.
- Added claim-level evidence and separate editorial/source dates. These are AI-assisted source reviews, not newly claimed human verification or hands-on product tests.
- Updated the EU personal-item tracker from the old negotiating status to the 2026 adoption notices, without assuming immediate application.
