Traveling has never been as easy as it is now. And, for better or for worse, flying remains one of the top means of transport (the number of flights in 2021 was estimated at 22.2 million). And it makes sense, as it's so convenient, especially if we're talking transcontinental. It would take 7 nights to sail from Southampton, UK, to New York, US, if you boarded the Queen Mary (but I'm sure the voyage would be delightful), whereas the same flight would only take 11 hours, 30 minutes.
