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; 169 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.
