$880 to fly 12 miles...

When flying, you usually expect to pay more for greater distance. Flying from San Francisco to Los Angeles is a lot cheaper than to Tokyo. However, it seems that there's a point at which you pay more the closer you get... I was on United's site and, just for the hell of it, priced out a flight from Oakland airport to San Francisco. I believe the distance between the two to be roughly 12 miles as the crow, I mean the jet, flies. Those are some very expensive miles, check it out:

The perceptive among you will have noticed that, although the title states "Oakland to San Francisco", the trip details actually have us flying from SFO to Sacramento (yes, that would be a bug). This is much more reasonable, after all SMF is a whopping 80miles away! And I bet they don't even serve drinks :-)
