50,000 flights at R11 each ....... Yea right !!!

Flysafair is advertising 50,000 tickets at only R11 each.... How is this possible ?? Lets do the sums - 50,000 seats is around 270 flights, R11 a passenger will bring R2000 per flight... so Flysafair is going to run 270 flight at a massive loss of earnings ?? I'd love to hear the **** artists at Flysafair explain this !!!
