Fuel Reserves

I am wondering if they had filed an en-route alternate to get around the initial fuel planning calculations to arrive with sufficent legal fuel at destination.

At the en-route diversion point the airline owner/pilot/captain decided there was sufficient fuel to continue to destination saving an en-route landing, however 'Murphy's Law' popped up with the Airbus fuel emergency at destination and an unplanned hold occurred using up those vital few kg's of fuel.

Just a thought.
