Booking flights

 Random tip: I book a lot of flights and have recently discovered what I think is by far the best search engine: Google Flights (https://www.google.com/flights). It's fast, easy to use and customize, and has a "brain" so it shows you the best flights right at the top, based mostly on price but also shortest travel time, etc. It also tells you that you can save X dollars if you fly a day earlier or later, etc. And because it doesn't actually book flights and charge the airlines a commission (like Orbitz, Travelocity and the other travel sites), it has nearly every airline (except Southwest, which nobody has).
