Discount airline Skybus entered the Milwaukee market on Wednesday.  The airline offers $10 flights to Columbus, Ohio once a day and from there to a lot of other destinations (again starting at $10).

The ticket prices work on a sliding scale where the first few tickets are sold for $10 and eventually sliding up to higher prices.

The system might seem vaguely familiar to you because the upstart bus company Megabus uses the same system with rides starting at $1 dollar.
