Could you please tell us which airlines are hiring with 0 hours on the Bus?
Even if there were any, you'd be somewhere in a very VERY long queue. Unless you have come through some form of cadetship where you are put forward to the airline (like with CTC, for example, or Ryanair's programme), you don't have a hope of finding anyone recruiting on to the 'bus with 0hrs on type at the moment.
