(similarly if you're in London and only have 72 hours, maybe you'd be better off going to Spain than to New York)
Transit time doesn't have to be proportional to actual distance, though. From Vancouver, I can easily hop one of multiple daily nonstops to PEK, PVG, HKG, TYO, ICN, etc. and be there in ~12 hours with a nice sleep on the way (in business class). It will easily take me that long to get to many places in the southern USA or eastern Canada.
