In travel hacking, there's plenty of "wrong" to go around. One popular hack is to use the "Dr." honorific from the pull-down menu when making a hotel reservation, regardless of your degree.

Similarly, you can save money on your airfare by using only part of your ticket, called "throwaway" ticketing. These "hacks" address endemic industry problems. Hotels shouldn't arbitrarily cancel their reservations without assisting guests. But they do. Airfares should be sensibly priced, and the only reason throwaway ticketing works is that a round-trip airline ticket almost always costs less than a one-way flight.
