Is this "interesting" as in "good" (e.g. we get more upgrades), "interesting" as in "bad" (e.g., we get fewer upgrades), or "interesting" as in "interesting" (e.g., eupgrades are free for flights which are a prime number of miles in length, but doubled if the number of miles has more than 3 prime factors)?
