- For
- Carry-on travelers checking bag and airline fit
- Worth noticing
- It distinguishes fare-dependent and unknown results from a confirmed fit, and says a fit is not a boarding guarantee.
Field notes
The checker’s stated catalog contains 206 products across brands and rules for 97 airlines; the homepage also says 800 high-confidence bag-and-airline pairs are curated for indexing. Its result vocabulary includes fare-dependent and unknown cases, rather than forcing every comparison into a yes-or-no answer. The site advises travelers to confirm requirements with the airline and notes that it is neither airline-endorsed nor IATA-certified.
