My wife’s father used to tell them, “good thing isn’t cheap, and cheap thing isn’t good”.
My buddy sent an email about a new Airline (RedJet: http://www.flyredjet.com) with flight within the Caribbean for as little as $9.99USD. Now don’t get me wrong, I love flying and was never afraid to fly. But if someone will put me on a flight for more than 10 minutes, and charge me only $10US. I am gonna think very hard about dat.
I have decided, ah think I aint gonna fly.
That is why I don’t eat cheap fast food like McDonald. The economics just doesn’t make sense. $.99 for a burger, which includes; bun, meat, lettuce, tomatoes, human labor to server it, transportation cost, raising and slaughtering the cow, and profits.  All this, I am getting for $.99 or even $2.99. I just figured that I am eating crap for that price.
So I checked it out and some flights were $39.99 between Jamaica and Trinidad. I still think that’s too cheap. With a full flight, of about 130 seats, that is only $5,000.00UD for aircraft, crew, booking agents, fuel, etc. Seems to be cutting the bone just too close.
