Insights from the data
Each page here takes one question that our published data can answer, counts it across every airline we cover, and states the denominator next to the result. Every figure is computed from the same rows you can download, so a reader can re-derive it rather than take our word for it.
What these pages are, and are not
- They are observations about published rules, not airline rankings. No airline is scored or ordered by how generous its allowance is, and no ordering in a chart implies a recommendation.
- Every article states its denominator: how many airlines the count is drawn from, and how many of those rows have been checked line by line. Today that is 155 airlines covered and 0 verified against the airline's own page.
- They describe what airlines publish, not what will happen at the gate. A rule can be recorded correctly and still be applied differently by staff on the day.

- Only 1 of 35 Airlines Changes Bag Size by Cabin
Airlines do vary carry-on rules by cabin — but almost always in pieces or kilograms, not in the size of the bag you may bring. Three further airlines are left out because their cabin rows also vary by route or fare.

- What a 7 kg Cabin Limit Actually Measures
A weight limit is only half a rule: it also matters whether it applies to each piece or to everything you carry. Some airlines publish the same number under both bases in the same tier.

- Why 60 of 155 Airlines Cannot Be Answered Yet
One 55 × 40 × 20 cm bag, checked against every airline in our data, returns four kinds of answer: it fits, it does not fit, the data cannot say yet, or there is no rule to apply. The largest of the four is the one we will not turn into a yes or a no.
