## About
Airline baggage rules change often and differ by fare, so this tool does not hold airline data. You enter your bag, then the limits for each flight from the airline's own site, and the checker shows which legs pass, which dimension fails and the total upgrade cost for the legs that fail.

## How to use
1. Paste or type your input into the box above.
2. Choose any options you need. Results update as you type.
3. Copy the result with the Copy button.

## FAQ
**Where do I find the right limits?** On each airline's baggage page for your exact fare. Limits differ between fares and some low-cost fares allow only a small under-seat item.

**Is the One Bag, Whole Trip Checker free?** Yes, with no sign-up or limits.
