I recently discovered that my last exam scheduled for the 15th of December, has been moved forward to the 10th. The significance of this is now I can fly home for the Christmas holidays 5 days earlier.

Upon calling the airline carrier to change the flight, I discovered the new date 11th Dec would have been $48 cheaper than the previous one on the 16th December. Great news, or so I thought!

However, the cost of changing the flight details was $150. Why so much?! I was willing to pay it, in order to spend 5 extra days at home, but still, it doesn't seem fair to charge customers so much for what seems like a relatively insignificant change.

Can anyone help explain this?
