Ryanair

Ryanair makes money by selling the cheapest plane tickets possible and then charging extra for bags, seats, and snacks. They give people a way to travel across Europe for the price of a pizza. They won by using only one type of plane and flying to smaller, cheaper airports to keep costs at rock bottom. Their secret is that they are so much cheaper than everyone else that travelers will put up with almost anything to save money. They use Labor Leverage to run a No Frills model distributed through their website.
