Cabin bag or checked bag: what should you compare?
Cabin bags and checked bags solve different travel problems, but both can change the cheapest airline for a route.
Cabin bags are useful for short trips and faster airport exits. Checked bags are often better for longer travel, family bookings, liquids, sports kit, or anything that does not fit into a small overhead allowance.
The key is to compare flights with the baggage choice already included. A fare that looks cheapest for personal-item-only travel may lose once a cabin bag or checked bag is added.

A better search flow
Choose the baggage you expect to need before reviewing the results. Then compare each airline by the same travel setup.

That makes the result fairer, easier to scan, and much closer to the booking decision travellers actually have to make.
