Air travel has a reputation for being expensive, but it all depends on where you're heading. What's the cheapest flight you can find?
While a flight from Boston to Rhode Island is probably about $23, the distance isn't very far. What we want is the most bang for your buck. What costs the least over a distance. So if you can get from New York to London for $200, that's an amazing deal. We want the cost per mile.
Here are the rules, since this is a slightly more involved QOTD than usual. First, you are looking for a one-way ticket. Take a screenshot of the purchase screen and post it in the comments below. List the airline, distance of the flight, and the cost per mile.
