How the comparison works
Methodology
The boundary between product data, editorial analysis and the final airline check.
Last updated: 15 August 2026
Start with the traveller's actual bags
A useful comparison gives every returned flight the same trip requirement. The current app accepts a small under-seat bag, a larger cabin bag and checked bags. In the latest production check, the response supplied fares and policy guidance but no complete offer-bound bag total. Those results remain incomplete rather than turning guidance into a price.
Do not turn missing data into a zero
An unknown fee is different from an included bag. Incomplete or warning-state evidence should stay visibly incomplete and must not become a precise-looking claim. The detailed ranking methodology explains inputs, sorting, exclusions and a worked comparison.
Editorial evidence is reviewed separately
Guides use the source hierarchy described on the sources page. A source list and review date explain the evidence used for the page. They do not make an airline rule permanent, so the airline checkout and current conditions remain the final authority.
Current limitations
Complete offer-bound bag totals were unavailable in the latest production check. Sports equipment, seat-selection fees, refund-rule scoring and complete route coverage are also not current app capabilities. Editorial pages and the calculator can help investigate those costs, but the app does not silently add them to a result total.
