Having a rare, occasional break at work, I decided to take a peek at what additional trips I could take. The prices for such trips recently has increased exponentionally due to it being the summer and the holiday season.
I compared various budget airlines, the prices were close. I wanted to get the cheapest fares available, but that would span over the weekdays, ie. Monday - Thursday. The flight are slightly cheaper, but that would mean losing out on being able to work and gain income on weekdays - Opportunity cost!
Sometimes, management accounting should never be taught to the budget traveller. It's bad for the heart.
