I recently launched BagCheck, a free tool for answering a practical travel question:
Will this bag work for this trip?
BagCheck lets you check backpacks, carry-ons and personal items against published airline size limits, compare bags side by side and plan multi-airline trips.
I built it as a personal learning project to sharpen newer technical skills by solving a problem I actually have. I travel frequently, like bags and was tired of repeatedly comparing manufacturer dimensions with airline baggage rules by hand.
What started as an experiment became a project of love.
One of the biggest lessons was that data quality matters more than database size. During the research, I found large public bag datasets with enough inconsistent, outdated or difficult-to-substantiate records to convince me that quantity alone is a poor benchmark.
BagCheck takes a more conservative approach. It emphasizes source-backed data, keeps uncertainty visible and separates physical fit from ticket allowance rather than turning incomplete information into a confident answer.
It is also independent and non-commercial. There are no affiliate commissions, paid placements or advertising influencing results. Core features do not require an account, and the site’s privacy approach is intentionally minimal.
BagCheck is not a review site and does not try to replace resources such as Pack Hacker, Carryology or One Bag Travel. Its focus is narrower:
I have this bag. Will it work?
I am flying these airlines. Which bags should I consider?
Will one bag work across my whole itinerary?
If that sounds useful, try BagCheck.
