I don&#x27;t think my price preferences (for flights or really much of anything else) can be boiled down to an algorithm. There are so many factors. What other travel do I have planned around the same time? Have I had a slew of crappy flights lately and want to treat myself? What am I going to be doing the day I arrive and depart (e.g. do I need to be rested enough to go right into meetings, or do I have a while to get settled?)? Am I flying on business or for pleasure?<p>I&#x27;m not sure I can even articulate all of the factors that go into my decision on what flight to purchase, but I wouldn&#x27;t be surprised if there are hundreds of them over the course of a year...
