Last month, United Airlines announced that it will give frequent flier miles based on dollars spent instead of miles flown. The number of miles per dollar vary, but basically the average traveler will get five miles per every dollar he or she spends.
To see how this affects the average traveler, Slate pulled the data and produced a pretty neat interactive:
Here’s how to interpret the graph: The dark grey line is the 5 miles per dollar mark that United has stated that it will pay. Each dot represents a flight. If the dot is above the line, you’re getting a better deal. If it’s below, then its a worse deal.
Based on this analysis, Slate produced a couple of rules in order to get the most frequent flier miles for your dollar. Here’s a sample: fly rural airports and avoid California.
