Cabin baggage guides
Clear answers to the baggage questions travellers actually ask — with real airline data and a checker, not just theory.
Each guide is built on our reviewed database of 151 airline baggage policies. The data-driven studies recompute their figures from that database every time the site is built, and every guide links back to the airline pages and official sources behind the numbers — so you can check the working, not just take our word for it.
About these guides — FAQ
Are these guides based on real airline rules?+
Yes. Every figure comes from our reviewed database of 151 airline baggage policies, and each guide links to the specific airline pages and official sources behind it. The data-driven studies recompute from that database at every build, so the numbers track the underlying rules rather than being written once and left to drift.
Which guide should I read first?+
If you are deciding what bag to buy or pack, start with "Personal item vs carry-on" and "How to measure a carry-on bag". If you want the underlying data, read the carry-on and personal-item studies that analyse every airline at once.
How are the guides different from the airline pages?+
The airline pages answer "what are this airline’s limits?". The guides answer the cross-airline questions — what fits the most airlines, how sizers work, how weight and size interact — using the same data but pulling it together into one explanation.
