It's a disgrace that you are not paid for positioning. Additionally there is always a fight about meals, the dead headers are not counted for pax meals and not included in the crew meal count so there is an issue on each flight. Business class seats are not blocked for EY travel and economy seats are purchased when flying on other carriers. The best thing is to avoid the 330F until the mess is sorted out and if already qualified do what it takes to get the message across to management.
