I've recently had a morbid fascination with an airline hopeful called Family Airlines:

Their plan is to fly old non-glass 747s domestically, crammed full of seats and advertising. They are trying to get DOT approval but they have a number of problems, including a business plan that simple arithmetic shows doesn't work at the fares they want to charge and a CEO who has spent time in prison for securities fraud. It's entertaining to watch it unfold, if seeing airline startups never get off the ground is your idea of fun
