Travel math people tend to get wrong: counting days under the Schengen 90/180 rule, working out the time difference and jet lag between two cities, checking whether a bag fits a common carry-on limit or your airline’s own, and splitting a shared bill when everyone paid something different. Entry rules and baggage limits change and border officers decide each case, so confirm visas, stays and bag sizes with the official sources.
