Yes what is there not to like about ANY revenue for an empty seat.

At one time in the years gone past an employee could purchase a 50% ID positive space ticket.

A spendy ticket of course but it was for any published fare that was regulated by the CAB - none
of this whatever you have in your pocket; ah let's see you a have a few coins left over so let's have
a fee for baggage - still some $ left over a fee for 24 hour seat assignment - still some $ tag on
the snack food - and the ultimate a service charge to make and call reservation. Follow along the
cruise ships are getting the hang of this nickel & dime fee thing - One hell of a nasty business virus !
