Again, a free voucher always...[EM]always[/EM] equates to more than just a butt in a seat. The fuel to haul them, the meal, the snack, the soda, the baggage, the agent that processes the voucher at check-in, the gate people that deal with that butt the baggage handlers taking care of baggage that is being transported for free, the cabin crew's time on board, cabin service cleaning up after them and that's just for starters. Don't even get into the accounting mess that a voucher creates, and reach for the aspirin bottle if that flight gets weight restricted and you either have to hold back the cash- cow cargo so you can haul [EM]them[/EM], or you end up giving [EM]them[/EM]......ANOTHER VOUCHER![BR][BR]Most of this was created by the bright idea of ticketless travel. Without a paper ticket, just passing a customer off onto another carrier (which used to be real customer service rather than stranding a customer at an airport) isn't as easy as it used to be - it's customers held hostage.[BR][BR]99.999% of what goes wrong at a carrier is blame that can be directed squarely at yield.[BR][BR]And just for grins.... figure out who to dump the delay on while you process all those oftentimes last to board voucher holders.....hmmmmm.
