You will like this recent story. There was a fella I know waiting in the crowded economy line at Qantas when a fella approached asking anyone if they wanted an upgrade to business or First Class. He decided he could wait no longer and would take up his offer. He was then ushered into a room. This gentlemen said "I will upgrade all your family but this is what you have to do." Go and buy a cheap bottle of wine and put $750 cash in there. Then give it to him.
So based on this status of affairs I would book economy and start looking for this fella at Qantas!!...lol
P.S. A great little business he has going there!!!...lol
