A319 Final Res aprox 990KG
A319 15 min extra = 50% of the above.

As I said this done on a daily basis within EZY with no problems.
Its those who don't understand the rules SOP's, inflight replanning rules and actions and those with little common sense that cause the problems!
If it was my jet I would fill the wings and put the trip in the centre, but as our company is fighting for survival then I am happy to do whatever I can to help the situation.
