Coming on A Jetplane 3

There's another thing that bothers me about airline, which I believe has been one of the greatest mysteries to mankind for years, just like the black hole, or Donald Trump's hair.
I am talking of course about the airfare.
Have you ever asked someone sit next to you on a flight how much he pays for the ride? I guarantee you that it's difference from how much you are paying. And it's usually lower.

Nobody understands how airline fixes the airfare, which I suspect is by having a chimpanzee hitting keypads randomly. I tried to ask my friend who worked in a travel agency once, but then he looked confused. "It involves Pythagoras ... and the first alphabet of your family name!"
Of course he was only kidding. I think. But I hope he wasn't, because the truth is that there are so many factors that influence the fare, such as the time of booking, the class type, the discount, and the direction of the wind.

So it's only common that your air ticket cost more than that of other passengers, which you usually compensate by stealing anything that can be fitted in your cabin bag. Fork, cup, blanket, flight attendant's phone number, you name it.

But now is the era of budget airlines, which somehow manage to give a same fare to everybody, with fortunately same service, except for the plastic utensils that they are using, which are not worth stealing.
